+## v0.11.0 (2019-01-10)
+This is Argo CD's biggest release ever and introduces a completely redesigned controller architecture.
+
+### New Features
+
+#### Performance & Scalability
+The application controller has a completely redesigned architecture which improved performance and
+scalability during application reconciliation.
+
+This was achieved by introducing an in-memory, live state cache of lightweight Kubernetes object 
+metadata. During reconciliation, the controller no longer performs expensive, in-line queries of app
+related resources in K8s API server, instead relying on the metadata available in the live state 
+cache. This dramatically improves performance and responsiveness, and is less burdensome to the K8s
+API server.
+
+#### Object relationship visualization for CRDs
+With the new controller design, Argo CD is now able to understand ownership relationship between
+*all* Kubernetes objects, not just the built-in types. This enables Argo CD to visualize
+parent/child relationships between all kubernetes objects, including CRDs.
+
+#### Multi-namespaced applications
+During sync, Argo CD will now honor any explicitly set namespace in a manifest. Manifests without a
+namespace will continue deploy to the "preferred" namespace, as specified in app's
+`spec.destination.namespace`. This enables support for a class of applications which install to
+multiple namespaces. For example, Argo CD can now install the
+[prometheus-operator](https://github.com/helm/charts/tree/master/stable/prometheus-operator)
+helm chart, which deploys some resources into `kube-system`, and others into the
+`prometheus-operator` namespace.
+
+#### Large application support
+Full resource objects are no longer stored in the Application CRD object status. Instead, only
+lightweight metadata is stored in the status, such as a resource's sync and health status.
+This change enabled Argo CD to support applications with a very large number of resources 
+(e.g. istio), and reduces the bandwidth requirements when listing applications in the UI.
+
+#### Resource lifecycle hook improvements
+Resource lifecycle hooks (e.g. PreSync, PostSync) are now visible/manageable from the UI.
+Additionally, bare Pods with a restart policy of Never can now be used as a resource hook, as an
+alternative to Jobs, Workflows.
+
+#### K8s recommended application labels
+The tracking label for resources has been changed to use `app.kubernetes.io/instance`, as
+recommended in [Kubernetes recommended labels](https://kubernetes.io/docs/concepts/overview/working-with-objects/common-labels/),
+(changed from `applications.argoproj.io/app-name`). This will enable applications managed by Argo CD
+to interoperate with other tooling which are also converging on this labeling, such as the
+Kubernetes dashboard. Additionally, Argo CD no longer injects any tracking labels at the
+`spec.template.metadata` level.
+
+#### External OIDC provider support
+Argo CD now supports auth delegation to an existing, external OIDC providers without the need for
+running Dex (e.g. Okta, OneLogin, Auth0, Microsoft, etc...)
+
+The optional, [Dex IDP OIDC provider](https://github.com/dexidp/dex) is still bundled as part of the
+default installation, in order to provide a seamless out-of-box experience, enabling Argo CD to
+integrate with non-OIDC providers, and to benefit from Dex's full range of
+[connectors](https://github.com/dexidp/dex/tree/master/Documentation/connectors).
+
+#### OIDC group bindings to Project Roles
+OIDC group claims from an OAuth2 provider can now be bound to a Argo CD project roles. Previously,
+group claims could only be managed in the centralized ConfigMap, `argocd-rbac-cm`. They can now be
+managed at a project level. This enables project admins to self service access to applications
+within a project.
+
+#### Declarative Argo CD configuration
+Argo CD settings can be now be configured either declaratively, or imperatively. The `argocd-cm`
+ConfigMap now has a `repositories` field, which can reference credentials in a normal Kubernetes
+secret which you can create declaratively, outside of Argo CD.
+
+#### Helm repository support
+Helm repositories can be configured at the system level, enabling the deployment of helm charts
+which have a dependency to external helm repositories.
+
+### Breaking changes:
+
+* Argo CD's resource names were renamed for consistency. For example, the application-controller
+  deployment was renamed to argocd-application-controller. When upgrading from v0.10 to v0.11,
+  the older resources should be pruned to avoid inconsistent state and controller in-fighting.
+
+* As a consequence to moving to recommended kubernetes labels, when upgrading from v0.10 to v0.11,
+  all applications will immediately be OutOfSync due to the change in tracking labels. This will
+  correct itself with another sync of the application. However, since Pods will be recreated, please
+  take this into consideration, especially if your applications are configured with auto-sync.
+
+* There was significant reworking of the `app.status` fields to reduce the payload size, simplify
+  the datastructure and remove fields which were no longer used by the controller. No breaking
+  changes were made in `app.spec`.
+
+* An older Argo CD CLI (v0.10 and below) will not be compatible with Argo CD v0.11. To keep
+  CI pipelines in sync with the API server, it is recommended to have pipelines download the CLI
+  directly from the API server https://${ARGOCD_SERVER}/download/argocd-linux-amd64 during the CI
+  pipeline.

+
+### Notes about upgrading from v0.8
+* Cluster wide resources should be allowed in default project (due to issue #330):
+
+```
+argocd project allow-cluster-resource default '*' '*'
+```
+
+* Projects now provide the ability to allow or deny deployments of cluster-scoped resources
+(e.g. Namespaces, ClusterRoles, CustomResourceDefinitions). When upgrading from v0.8 to v0.9, to
+match the behavior of v0.8 (which did not have restrictions on deploying resources) and continue to
+allow deployment of cluster-scoped resources, an additional command should be run:
+
+```bash
+argocd proj allow-cluster-resource default '*' '*'
+```
+
+The above command allows the `default` project to deploy any cluster-scoped resources which matches
+the behavior of v0.8.
+
+* The secret keys in the argocd-secret containing the TLS certificate and key, has been renamed from
+  `server.crt` and `server.key` to the standard `tls.crt` and `tls.key` keys. This enables Argo CD
+  to integrate better with Ingress and cert-manager. When upgrading to v0.9, the `server.crt` and
+  `server.key` keys in argocd-secret should be renamed to the new keys.
+

+
+## v0.8.0 (2018-09-04)
+
+### Notes about upgrading from v0.7
+* The RBAC model has been improved to support explicit denies. What this means is that any previous
+RBAC policy rules, need to be rewritten to include one extra column with the effect:
+`allow` or `deny`. For example, if a rule was written like this:
+    ```
+    p, my-org:my-team, applications, get, */*
+    ```
+    It should be rewritten to look like this:
+    ```
+    p, my-org:my-team, applications, get, */*, allow
+    ```
+
+### Changes since v0.7:
++ Support kustomize as an application source (issue #510)
++ Introduce project tokens for automation access (issue #498)
++ Add ability to delete a single application resource to support immutable updates (issue #262)
++ Update RBAC model to support explicit denies (issue #497)
++ Ability to view Kubernetes events related to application projects for auditing
++ Add PVC healthcheck to controller (issue #501)
++ Run all containers as an unprivileged user (issue #528)
+* Upgrade ksonnet to v0.12.0
+* Add readiness probes to API server (issue #522)
+* Use gRPC error codes instead of fmt.Errorf (#532)
+- API discovery becomes best effort when partial resource list is returned (issue #524)

-## Requirements
-Make sure you have following tools installed
+# Contributing
+## Before You Start
+
+You must install and run the ArgoCD using a local Kubernetes (e.g. Docker for Desktop or Minikube) first. This will help you understand the application, but also get your local environment set-up.
+
+Then, to get a good grounding in Go, try out [the tutorial](https://tour.golang.org/).
+
+## Pre-requisites
+
+Install:
+
 * [docker](https://docs.docker.com/install/#supported-platforms)
 * [golang](https://golang.org/)
 * [dep](https://github.com/golang/dep)
 * [protobuf](https://developers.google.com/protocol-buffers/)
 * [ksonnet](https://github.com/ksonnet/ksonnet#install)
 * [helm](https://github.com/helm/helm/releases)
+* [kustomize](https://github.com/kubernetes-sigs/kustomize/releases)
 * [go-swagger](https://github.com/go-swagger/go-swagger/blob/master/docs/install.md)
 * [jq](https://stedolan.github.io/jq/)
 * [kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl/).
+* [minikube](https://kubernetes.io/docs/setup/minikube/) or Docker for Desktop
 
 ```
-$ brew tap go-swagger/go-swagger
-$ brew install go dep protobuf kubectl ksonnet/tap/ks kubernetes-helm jq go-swagger
-$ go get -u github.com/golang/protobuf/protoc-gen-go
-$ go get -u github.com/go-swagger/go-swagger/cmd/swagger
-$ go get -u github.com/grpc-ecosystem/grpc-gateway/protoc-gen-grpc-gateway
-$ go get -u github.com/grpc-ecosystem/grpc-gateway/protoc-gen-swagger
+brew tap go-swagger/go-swagger
+brew install go dep protobuf kubectl ksonnet/tap/ks kubernetes-helm jq go-swagger 
 ```
 
-Nice to have [gometalinter](https://github.com/alecthomas/gometalinter) and [goreman](https://github.com/mattn/goreman):
+Set up environment variables (e.g. is `~/.bashrc`):
 
 ```
-$ go get -u gopkg.in/alecthomas/gometalinter.v2 github.com/mattn/goreman && gometalinter.v2 --install
+export GOPATH=~/go
+export PATH=$PATH:$GOPATH/bin
+```
+
+Install go dependencies:
+
+```
+go get -u github.com/golang/protobuf/protoc-gen-go
+go get -u github.com/go-swagger/go-swagger/cmd/swagger
+go get -u github.com/grpc-ecosystem/grpc-gateway/protoc-gen-grpc-gateway
+go get -u github.com/grpc-ecosystem/grpc-gateway/protoc-gen-swagger
+go get -u github.com/golangci/golangci-lint/cmd/golangci-lint 
+go get -u github.com/mattn/goreman 
 ```
 
 ## Building
 
 ```
-$ go get -u github.com/argoproj/argo-cd
-$ dep ensure
-$ make
+go get -u github.com/argoproj/argo-cd
+dep ensure
+make
 ```
-NOTE: The make command can take a while, and we recommend building the specific component you are working on
+
+The make command can take a while, and we recommend building the specific component you are working on
+
+* `make codegen` - Builds protobuf and swagger files
 * `make cli` - Make the argocd CLI tool
 * `make server` - Make the API/repo/controller server
-* `make codegen` - Builds protobuf and swagger files
 * `make argocd-util` - Make the administrator's utility, used for certain tasks such as import/export
 
-## Generating ArgoCD manifests for a specific image repository/tag
+## Running Tests
 
-During development, the `update-manifests.sh` script, can be used to conveniently regenerate the
-ArgoCD installation manifests with a customized image namespace and tag. This enables developers
-to easily apply manifests which are using the images that they pushed into their personal container
-repository.
+To run unit tests:
 
 ```
-$ IMAGE_NAMESPACE=jessesuen IMAGE_TAG=latest ./hack/update-manifests.sh
-$ kubectl apply -n argocd -f ./manifests/install.yaml
+make test
 ```
 
-## Running locally
-
-You need to have access to kubernetes cluster (including [minikube](https://kubernetes.io/docs/tasks/tools/install-minikube/) or [docker edge](https://docs.docker.com/docker-for-mac/install/) ) in order to run Argo CD on your laptop:
-
-* install kubectl: `brew install kubectl`
-* make sure `kubectl` is connected to your cluster (e.g. `kubectl get pods` should work).
-* install application CRD using following command:
+To run e2e tests:
 
 ```
-$ kubectl create -f install/manifests/01_application-crd.yaml
+make test-e2e
 ```
 
-* start Argo CD services using [goreman](https://github.com/mattn/goreman):
+## Running Locally
+
+It is much easier to run and debug if you run ArgoCD on your local machine than in the Kubernetes cluster.
+
+You should scale the deployemnts to zero:
 
 ```
-$ goreman start
+kubectl -n argocd scale deployment.extensions/argocd-application-controller --replicas 0
+kubectl -n argocd scale deployment.extensions/argocd-dex-server --replicas 0
+kubectl -n argocd scale deployment.extensions/argocd-repo-server --replicas 0
+kubectl -n argocd scale deployment.extensions/argocd-server --replicas 0
+kubectl -n argocd scale deployment.extensions/argocd-redis --replicas 0
 ```
 
-## Troubleshooting
-* Ensure argocd is installed: ./dist/argocd install
-* Ensure you're logged in: ./dist/argocd login --username admin --password <whatever password you set at install> localhost:8080
-* Ensure that roles are configured: kubectl create -f install/manifests/02c_argocd-rbac-cm.yaml
-* Ensure minikube is running: minikube stop && minikube start
-* Ensure Argo CD is aware of minikube: ./dist/argocd cluster add minikube
+Then checkout and build the UI next to your code
+
+```
+cd ~/go/src/github.com/argoproj
+git clone git@github.com:argoproj/argo-cd-ui.git
+```
+
+Follow the UI's [README](https://github.com/argoproj/argo-cd-ui/blob/master/README.md) to build it.
+
+Note: you'll need to use the https://localhost:6443 cluster now.
+
+Then start the services:
+
+```
+cd ~/go/src/github.com/argoproj/argo-cd
+goreman start
+```
+
+You can now execute `argocd` command against your locally running ArgoCD by appending `--server localhost:8080 --plaintext --insecure`, e.g.:
+
+```
+argocd app set guestbook --path guestbook --repo https://github.com/argoproj/argocd-example-apps.git --dest-server https://localhost:6443  --dest-namespace default --server localhost:8080 --plaintext --insecure
+```
+
+You can open the UI: http://localhost:8080
+
+Note: you'll need to use the https://kubernetes.default.svc cluster now.
+
+## Running Local Containers
+
+You may need to run containers locally, so here's how:
+
+Create login to Docker Hub, then login.
+
+```
+docker login
+```
+
+Add your username as the environment variable, e.g. to your `~/.bash_profile`:
+
+```
+export IMAGE_NAMESPACE=alexcollinsintuit
+```
+
+If you have not built the UI image (see [the UI README](https://github.com/argoproj/argo-cd-ui/blob/master/README.md)), then do the following:
+
+```
+docker pull argoproj/argocd-ui:latest
+docker tag argoproj/argocd-ui:latest $IMAGE_NAMESPACE/argocd-ui:latest
+docker push $IMAGE_NAMESPACE/argocd-ui:latest
+```
+
+Build the images:
+
+```
+DOCKER_PUSH=true make image
+```
+
+Update the manifests:
+
+```
+make manifests
+```
+
+Install the manifests:
+
+```
+kubectl -n argocd apply --force -f manifests/install.yaml
+```
+
+Scale your deployments up:
+
+```
+kubectl -n argocd scale deployment.extensions/argocd-application-controller --replicas 1
+kubectl -n argocd scale deployment.extensions/argocd-dex-server --replicas 1
+kubectl -n argocd scale deployment.extensions/argocd-repo-server --replicas 1
+kubectl -n argocd scale deployment.extensions/argocd-server --replicas 1
+kubectl -n argocd scale deployment.extensions/argocd-redis --replicas 1
+```
+
+Now you can set-up the port-forwarding (see [README](README.md)) and open the UI or CLI.
+
+## Pre-commit Checks
+
+Before you commit, make sure you've formatted and linted your code, or your PR will fail CI:
+
+```
+STAGED_GO_FILES=$(git diff --cached --name-only | grep ".go$")
+
+gofmt -w $STAGED_GO_FILES
+
+make codgen
+make precommit ;# lint and test
+```

+
+* Make sure required binaries are available in `argocd-repo-server` pod. The binaries can be added via volume mounts or using custom image (see [custom_tools](custom_tools.md)).
+* Register a new plugin in `argocd-cm` ConfigMap:
+
+```yaml
+data:
+  configManagementPlugins: |
+    - name: pluginName
+      init:                          # Optional command to initialize application source directory

+        command: ["sample command"]
+        args: ["sample args"]
+```
+
+The `generate` command must print a valid YAML stream to stdout. Both `init` and `generate` commands are executed inside the application source directory.
+Commands have access to system environment variables and following additional variables:
+
+`ARGOCD_APP_NAME` - name of application; `ARGOCD_APP_NAMESPACE` - destination application namespace

+# Automated Sync Policy
+
+Argo CD has the ability to automatically sync an application when it detects differences between
+the desired manifests in git, and the live state in the cluster. A benefit of automatic sync is that
+CI/CD pipelines no longer need direct access to the Argo CD API server to perform the deployment.
+Instead, the pipeline makes a commit and push to the git repository with the changes to the
+manifests in the tracking git repo.
+
+To configure automated sync run:
+```bash
+argocd app set <APPNAME> --sync-policy automated
+```
+
+Alternatively, if creating the application an application manifest, specify a syncPolicy with an
+`automated` policy.
+```yaml
+spec:
+  syncPolicy:
+    automated: {}
+```
+
+## Automatic Pruning
+
+By default (and as a safety mechanism), automated sync will not delete resources when Argo CD detects
+the resource is no longer defined in git. To prune the resources, a manual sync can always be
+performed (with pruning checked). Pruning can also be enabled to happen automatically as part of the
+automated sync by running:
+
+```bash
+argocd app set <APPNAME> --auto-prune
+```
+
+Or by setting the prune option to true in the automated sync policy:
+
+```yaml
+spec:
+  syncPolicy:
+    automated:
+      prune: true
+```
+
+## Automated Sync Semantics
+
+* An automated sync will only be performed if the application is OutOfSync. Applications in a
+  Synced or error state will not attempt automated sync.
+* Automated sync will only attempt one synchronization per unique combination of commit SHA1 and
+  application parameters. If the most recent successful sync in the history was already performed
+  against the same commit-SHA and parameters, a second sync will not be attempted.
+* Automatic sync will not reattempt a sync if the previous sync attempt against the same commit-SHA
+  and parameters had failed.
+* Rollback cannot be performed against an application with automated sync enabled.

+# Best Practices
+
+## Separating config vs. source code repositories
+
+Using a separate git repository to hold your kubernetes manifests, keeping the config separate
+from your application source code, is highly recommended for the following reasons:
+
+1. It provides a clean separation of application code vs. application config. There will be times
+   when you wish to modify just the manifests without triggering an entire CI build. For example,
+   you likely do _not_ want to trigger a build if you simply wish to bump the number of replicas in
+   a Deployment spec.
+
+2. Cleaner audit log. For auditing purposes, a repo which only holds configuration will have a much
+   cleaner git history of what changes were made, without the noise coming from check-ins due to
+   normal development activity.
+
+3. Your application may be comprised of services built from multiple git repositories, but is
+   deployed as a single unit. Oftentimes, microservices applications are comprised of services
+   with different versioning schemes, and release cycles (e.g. ELK, Kafka + Zookeeper). It may not
+   make sense to store the manifests in one of the source code repositories of a single component.
+
+4. Separation of access. The developers who are developing the application, may not necessarily be 
+   the same people who can/should push to production environments, either intentionally or
+   unintentionally. By having separate repos, commit access can be given to the source code repo,
+   and not the application config repo.
+
+5. If you are automating your CI pipeline, pushing manifest changes to the same git repository can
+   trigger an infinite loop of build jobs and git commit triggers. Having a separate repo to push
+   config changes to, prevents this from happening.
+
+
+## Leaving room for imperativeness
+
+It may be desired to leave room for some imperativeness/automation, and not have everything defined
+in your git manifests. For example, if you want the number of your deployment's replicas to be
+managed by [Horizontal Pod Autoscaler](https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/),
+then you would not want to track `replicas` in git.
+
+```yaml
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: nginx-deployment
+spec:
+  # do not include replicas in the manifests if you want replicas to be controlled by HPA
+  # replicas: 1
+  template:
+    spec:
+      containers:
+      - image: nginx:1.7.9
+        name: nginx
+        ports:
+        - containerPort: 80
+...
+```
+
+
+## Ensuring manifests at git revisions are truly immutable
+
+When using templating tools like `helm` or `kustomize`, it is possible for manifests to change
+their meaning from one day to the next. This is typically caused by changes made to an upstream helm
+repository or kustomize base.
+
+For example, consider the following kustomization.yaml
+```yaml
+bases:
+- github.com/argoproj/argo-cd//manifests/cluster-install
+```
+
+The above kustomization has a remote base to he HEAD revision of the argo-cd repo. Since this
+is not stable target, the manifests for this kustomize application can suddenly change meaning, even without
+any changes to your own git repository.
+
+A better version would be to use a git tag or commit SHA. For example:
+```yaml
+bases:
+- github.com/argoproj/argo-cd//manifests/cluster-install?ref=v0.11.1
+```

+# Automation from CI Pipelines
+
+Argo CD follows the GitOps model of deployment, where desired configuration changes are first
+pushed to git, and the cluster state then syncs to the desired state in git. This is a departure
+from imperative pipelines which do not traditionally use git repositories to hold application
+config.
+
+To push new container images into to a cluster managed by Argo CD, the following workflow (or 
+variations), might be used:
+
+
+1. Build and publish a new container image
+
+    ```
+    docker build -t mycompany/guestbook:v2.0 .
+    docker push mycompany/guestbook:v2.0
+    ```
+
+2. Update the local manifests using your preferred templating tool, and push the changes to git.
+
+    NOTE: the use of a different git repository to hold your kubernetes manifests (separate from
+    your application source code), is highly recommended. See [best practices](best_practices.md)
+    for further rationale.
+
+    ```
+    git clone https://github.com/mycompany/guestbook-config.git
+    cd guestbook-config
+
+    # kustomize
+    kustomize edit set imagetag mycompany/guestbook:v2.0
+
+    # ksonnet
+    ks param set guestbook image mycompany/guestbook:v2.0
+
+    # plain yaml
+    kubectl patch --local -f config-deployment.yaml -p '{"spec":{"template":{"spec":{"containers":[{"name":"guestbook","image":"mycompany/guestbook:v2.0"}]}}}}' -o yaml
+
+    git add . -m "Update guestbook to v2.0"
+    git push
+    ```
+
+3. Synchronize the app (Optional)
+
+    For convenience, the argocd CLI can be downloaded directly from the API server. This is
+    useful so that the CLI used in the CI pipeline is always kept in-sync and uses argocd binary
+    that is always compatible with the Argo CD API server.
+
+    ```
+    export ARGOCD_SERVER=argocd.mycompany.com
+    export ARGOCD_AUTH_TOKEN=<JWT token generated from project>
+    curl -sSL -o /usr/local/bin/argocd https://${ARGOCD_SERVER}/download/argocd-linux-amd64
+    argocd app sync guestbook
+    argocd app wait guestbook
+    ```
+
+    If [automated synchronization](auto_sync.md) is configured for the application, this step is
+    unnecessary. The controller will automatically detect the new config (fast tracked using a
+    [webhook](webhook.md), or polled every 3 minutes), and automatically sync the new manifests.

+other than what Argo CD bundles. Some reasons to do this might be:
+
+* To upgrade/downgrade to a specific version of a tool due to bugs or bug fixes.
+* To install additional dependencies which to be used by kustomize's configmap/secret generators
+  (e.g. curl, vault, gpg, AWS CLI)
+* In the future, to install a [custom templating tool](https://github.com/argoproj/argo-cd/issues/701)
+
+As the Argo CD repo-server is the single service responsible for generating Kubernetes manifests, it
+can be customized to use alternative toolchain required by your environment.
+
+## Adding tools via volume mounts
+
+The first technique is to use an `init` container and a `volumeMount` to copy a different verison of
+a tool into the repo-server container. In the following example, an init container is overwriting
+the helm binary with a different version than what is bundled in Argo CD:
+
+```yaml
+    spec:
+      # 1. Define an emptyDir volume which will hold the custom binaries
+      volumes:
+      - name: custom-tools
+        emptyDir: {}
+      # 2. Use an init container to download/copy custom binaries into the emptyDir
+      initContainers:
+      - name: download-tools
+        image: alpine:3.8
+        command: [sh, -c]
+        args:
+        - wget -qO- https://storage.googleapis.com/kubernetes-helm/helm-v2.12.3-linux-amd64.tar.gz | tar -xvzf - &&
+          mv linux-amd64/helm /custom-tools/
+        volumeMounts:
+        - mountPath: /custom-tools
+          name: custom-tools
+      # 3. Volume mount the custom binary to the bin directory (overriding the existing version)
+      containers:
+      - name: argocd-repo-server
+        volumeMounts:
+        - mountPath: /usr/local/bin/helm
+          name: custom-tools
+          subPath: helm
+```
+
+## BYOI (build your own image)
+
+Sometimes replacing a binary isn't sufficient and you need to install other dependencies. The
+following example builds an entirely customized repo-server from a Dockerfile, installing extra
+dependencies that may be needed for generating manifests.
+
+```Dockerfile
+FROM argoproj/argocd:latest
+
+# Switch to root for the ability to perform install
+USER root
+
+# Install tools needed for your repo-server to retrieve & decrypt secrets, render manifests 
+# (e.g. curl, awscli, gpg, sops)
+RUN apt-get update && \
+    apt-get install -y \
+        curl \
+        awscli \
+        gpg && \
+    apt-get clean && \
+    rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* && \
+    curl -o /usr/local/bin/sops -L https://github.com/mozilla/sops/releases/download/3.2.0/sops-3.2.0.linux && \
+    chmod +x /usr/local/bin/sops

+# Declarative Setup
+
+Argo CD applications, projects and settings can be defined declaratively using Kubernetes manifests.
+
+## Quick Reference
+| Name | Kind | Description |
+|------|------|-------------|
+| [`argocd-cm.yaml`](argocd-cm.yaml) | ConfigMap | General Argo CD configuration |
+| [`argocd-secret.yaml`](argocd-secret.yaml) | Secret | Password, Certificates, Signing Key |

+| [`application.yaml`](application.yaml) | Application | Example application spec |
+| [`project.yaml`](argocd-rbac-cm.yaml) | AppProject | Example project spec |
+
+## Applications
+
+The Application CRD is the Kubernetes resource object representing a deployed application instance
+in an environment. It is defined by two key pieces of information:
+* `source` reference to the desired state in git (repository, revision, path, environment)
+* `destination` reference to the target cluster and namespace.
+
+A minimal Application spec is as follows:
+
+```yaml
+apiVersion: argoproj.io/v1alpha1
+kind: Application
+metadata:
+  name: guestbook
+spec:
+  project: default
+  source:
+    repoURL: https://github.com/argoproj/argocd-example-apps.git
+    targetRevision: HEAD
+    path: guestbook
+  destination:
+    server: https://kubernetes.default.svc
+    namespace: guestbook
+```
+
+See [application.yaml](application.yaml) for additional fields
+
+## Projects
+The AppProject CRD is the Kubernetes resource object representing a logical grouping of applications.
+It is defined by the following key pieces of information:
+* `sourceRepos` reference to the repositories that applications within the project can pull manifests from.
+* `destinations` reference to clusters and namespaces that applications within the project can deploy into.
+* `roles` list of entities with definitions of their access to resources within the project.
+
+An example spec is as follows:
+
+```yaml
+apiVersion: argoproj.io/v1alpha1
+kind: AppProject
+metadata:
+  name: my-project
+spec:
+  description: Example Project
+  # Allow manifests to deploy from any git repos
+  sourceRepos:
+  - '*'
+  # Only permit applications to deploy to the guestbook namespace in the same cluster
+  destinations:
+  - namespace: guestbook
+    server: https://kubernetes.default.svc
+  # Deny all cluster-scoped resources from being created, except for Namespace
+  clusterResourceWhitelist:
+  - group: ''
+    kind: Namespace
+  # Allow all namespaced-scoped resources to be created, except for ResourceQuota, LimitRange, NetworkPolicy
+  clusterResourceWhitelist:
+  - group: ''
+    kind: ResourceQuota
+  - group: ''
+    kind: LimitRange
+  - group: ''
+    kind: NetworkPolicy
+  roles:
+  # A role which provides read-only access to all applications in the project
+  - name: read-only
+    description: Read-only privileges to my-project
+    policies:
+    - p, proj:my-project:read-only, applications, get, my-project/*, allow
+    groups:
+    - my-oidc-group
+  # A role which provides sync privileges to only the guestbook-dev application, e.g. to provide
+  # sync privileges to a CI system
+  - name: ci-role
+    description: Sync privileges for guestbook-dev
+    policies:
+    - p, proj:my-project:ci-role, applications, sync, my-project/guestbook-dev, allow
+    # NOTE: JWT tokens can only be generated by the API server and the token is not persisted
+    # anywhere by Argo CD. It can be prematurely revoked by removing the entry from this list.
+    jwtTokens:
+    - iat: 1535390316
+```
+
+## Repositories
+
+Repository credentials are stored in secret. Use following steps to configure a repo:
+
+1. Create secret which contains repository credentials. Consider using [bitnami-labs/sealed-secrets](https://github.com/bitnami-labs/sealed-secrets) to store encrypted secret
+definition as a Kubernetes manifest.
+
+2. Register repository in `argocd-cm` config map. Each repository must have `url` field and `usernameSecret`, `passwordSecret` or `sshPrivateKeySecret`.
+
+Example:
+
+```yaml
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: argocd-cm
+data:
+  repositories: |
+    - url: https://github.com/argoproj/my-private-repository
+      passwordSecret:
+        name: my-secret
+        key: password
+      usernameSecret:
+        name: my-secret
+        key: username
+      sshPrivateKeySecret:
+        name: my-secret
+        key: sshPrivateKey
+```
+
+## Clusters
+
+Cluster credentials are stored in secrets same as repository credentials but does not require entry in `argocd-cm` config map. Each secret must have label
+`argocd.argoproj.io/secret-type: cluster`.
+
+The secret data must include following fields:
+* `name` - cluster name
+* `server` - cluster api server url
+* `config` - JSON representation of following data structure:
+
+```yaml
+# Basic authentication settings
+username: string
+password: string
+# Bearer authentication settings
+bearerToken: string
+# IAM authentication configuration
+awsAuthConfig:
+    clusterName: string
+    roleARN: string
+# Transport layer security configuration settings
+tlsClientConfig:
+    # PEM-encoded bytes (typically read from a client certificate file).
+    caData: string
+    # PEM-encoded bytes (typically read from a client certificate file).
+    certData: string
+    # Server should be accessed without verifying the TLS certificate
+    insecure: boolean
+    # PEM-encoded bytes (typically read from a client certificate key file).
+    keyData: string
+    # ServerName is passed to the server for SNI and is used in the client to check server
+    # ceritificates against. If ServerName is empty, the hostname used to contact the
+    # server is used.
+    serverName: string
+```
+
+
+Cluster secret example:
+
+```yaml
+apiVersion: v1
+kind: Secret
+metadata:
+  name: mycluster-secret
+  labels:
+    argocd.argoproj.io/secret-type: cluster
+type: Opaque
+stringData:
+  name: mycluster.com
+  server: https://mycluster.com
+  config: |
+    {
+      "bearerToken": "<authentication token>",
+      "tlsClientConfig": {
+        "insecure": false,
+        "caData": "<base64 encoded certificate>"
+      }
+    }
+```
+
+## Helm Chart repositories
+
+Non standard Helm Chart repositories have to be registered under the `helm.repositories` key in the
+`argocd-cm` ConfigMap. Each repository must have `url` and `name` fields. For private Helm repos you
+may need to configure access credentials and HTTPS settings using `usernameSecret`, `passwordSecret`,
+`caSecret`, `certSecret` and `keySecret` fields.
+
+Example:
+
+```yaml
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: argocd-cm
+data:
+  helm.repositories: |
+    - url: https://storage.googleapis.com/istio-prerelease/daily-build/master-latest-daily/charts
+      name: istio.io
+    - url: https://argoproj.github.io/argo-helm
+      name: argo
+      usernameSecret:
+        name: my-secret
+        key: username
+      passwordSecret:
+        name: my-secret
+        key: password
+      caSecret:
+        name: my-secret
+        key: ca
+      certSecret:
+        name: my-secret
+        key: cert
+      keySecret:
+        name: my-secret
+        key: key
+```
+
+## Resource Exclusion
+
+Resources can be excluded from discovery and sync so that ArgoCD is unaware of them. For example, `events.k8s.io` and `metrics.k8s.io` are always excluded. Use cases:
+
+* You have temporal issues and you want to exclude problematic resources.
+* There are many of a kind of resources that impacts ArgoCD's performance.
+* Restrict ArgoCD's access to certain kinds of resources, e.g. secrets. See [security.md#cluster-rbac](security.md#cluster-rbac).
+
+To configure this, edit the `argcd-cm` config map:
+
+```
+kubectl edit configmap argocd-cm -n argocdconfigmap/argocd-cm edited
+```
+
+Add `resource.exclusions`, e.g.:
+
+```yaml
+apiVersion: v1
+data:
+  resource.exclusions: |
+    - apiGroups:
+      - "*"
+      kinds:
+      - "*"
+      clusters:
+      - https://192.168.0.20
+kind: ConfigMap
+```
+
+The `resource.exclusions` node is a list of objects. Each object can have:
+
+- `apiGroups` A list of globs to match the API group.
+- `kinds` A list of kinds to match. Can be "*" to match all.
+- `cluster` A list of globs to match the cluster.
+
+If all three match, then the resource is ignored.
+
+Notes:
+
+* Quote globs in your YAML to avoid parsing errors.
+* Invalid globs result in the whole rule being ignored.
+* If you add a rule that matches existing resources, these will appear in the interface as `OutOfSync`.
+
+## SSO & RBAC
+
+* SSO configuration details: [SSO](sso.md)
+* RBAC configuration details: [RBAC](rbac.md)
+
+## Manage Argo CD using Argo CD
+
+Argo CD is able to manage itself since all settings are represented by Kubernetes manifests. The suggested way is to create [Kustomize](https://github.com/kubernetes-sigs/kustomize)
+based application which uses base Argo CD manifests from https://github.com/argoproj/argo-cd and apply required changes on top.
+
+Example of `kustomization.yaml`:
+
+```yaml
+bases:
+- github.com/argoproj/argo-cd//manifests/cluster-install?ref=v0.10.6
+
+# additional resources like ingress rules, cluster and repository secrets.
+resources:
+- clusters-secrets.yaml
+- repos-secrets.yaml
+
+# changes to config maps
+patchesStrategicMerge:
+- overlays/argo-cd-cm.yaml
+```
+
+The live example of self managed Argo CD config is available at https://cd.apps.argoproj.io and with configuration
+stored at [argoproj/argoproj-deployments](https://github.com/argoproj/argoproj-deployments/tree/master/argocd).

+# Diffing Customization
+
+It is possible for an application to be `OutOfSync` even immediately after a successful Sync operation. Some reasons for this might be:
+
+* There is a bug in the manifest, where it contains extra/unknown fields from the actual K8s spec. These extra fields would get dropped when querying Kubernetes for the live state,
+resulting in an `OutOfSync` status indicating a missing field was detected.
+* The sync was performed (with pruning disabled), and there are resources which need to be deleted.
+* A controller or [mutating webhook](https://kubernetes.io/docs/reference/access-authn-authz/admission-controllers/#mutatingadmissionwebhook) is altering the object after it was
+submitted to Kubernetes in a manner which contradicts Git.
+* A Helm chart is using a template function such as [`randAlphaNum`](https://github.com/helm/charts/blob/master/stable/redis/templates/secret.yaml#L16),
+which generates different data every time `helm template` is invoked.
+* For Horizontal Pod Autoscaling (HPA) objects, the HPA controller is known to reorder `spec.metrics`
+  in a specific order. See [kubernetes issue #74099](https://github.com/kubernetes/kubernetes/issues/74099).
+  To work around this, you can order `spec.replicas` in git in the same order that the controller
+  prefers.
+
+In case it is impossible to fix the upstream issue, Argo CD allows you to optionally ignore differences of problematic resources.
+The diffing customization can be configured for single or multiple application resources or at a system level.
+
+## Application level configuration
+
+Argo CD allows ignoring differences at a specific JSON path. The following sample application is configured to ignore differences in `spec.replicas` for all deployments:
+
+```yaml
+spec:
+  ignoreDifferences:
+  - group: apps
+    kind: Deployment
+    jsonPointers:
+    - /spec/replicas
+```
+
+The above customization could be narrowed to a resource with the specified name and optional namespace:
+
+```yaml
+spec:
+  ignoreDifferences:
+  - group: apps
+    kind: Deployment
+    name: guestbook
+    namespace: default
+    jsonPointers:
+    - /spec/replicas
+```
+
+## System-level configuration
+
+The comparison of resources with well-known issues can be customized at a system level. Ignored differences can be configured for a specified group and kind
+in `resource.customizations` key of `argocd-cm` ConfigMap. Following is an example of a customization which ignores the `caBundle` field
+of a `MutatingWebhookConfiguration` webhooks:
+
+```yaml
+data:
+  resource.customizations: |
+    admissionregistration.k8s.io/MutatingWebhookConfiguration:
+      ignoreDifferences:
+        jsonPointers:
+        - webhooks/0/clientConfig/caBundle
+```

+# FAQ
+
+## Why is my application still `OutOfSync` immediately after a successful Sync?
+
+See [Diffing](diffing.md) documentation for reasons resources can be OutOfSync, and ways to configure
+Argo CD to ignore fields when differences are expected.
+
+
+## Why is my application stuck in `Progressing` state?
+
+Argo CD provides health for several standard Kubernetes types. The `Ingress` and `StatefulSet` types have known issues which might cause health check
+to return `Progressing` state instead of `Healthy`.
+
+* `Ingress` is considered healthy if `status.loadBalancer.ingress` list is non-empty, with at least one value for `hostname` or `IP`. Some ingress controllers
+ ([contour](https://github.com/heptio/contour/issues/403), [traefik](https://github.com/argoproj/argo-cd/issues/968#issuecomment-451082913)) don't update
+ `status.loadBalancer.ingress` field which causes `Ingress` to stuck in `Progressing` state forever.
+
+* `StatufulSet` is considered healthy if value of `status.updatedReplicas` field matches to `spec.replicas` field. Due to Kubernetes bug
+[kubernetes/kubernetes#68573](https://github.com/kubernetes/kubernetes/issues/68573) the `status.updatedReplicas` is not populated. So unless you run Kubernetes version which
+include the fix [kubernetes/kubernetes#67570](https://github.com/kubernetes/kubernetes/pull/67570) `StatefulSet` might stay in `Progressing` state.
+
+As workaround Argo CD allows providing [health check](health.md) customization which overrides default behavior.
+
+## I forgot the admin password, how do I reset it?
+
+Edit the `argocd-secret` secret and update the `admin.password` field with a new bcrypt hash. You
+can use a site like https://www.browserling.com/tools/bcrypt to generate a new hash. Another option
+is to delete both the `admin.password` and `admin.passwordMtime` keys and restart argocd-server.

-By default, the ArgoCD API server is not exposed with an external IP. To expose the API server,
-change the service type to `LoadBalancer`:
+### Service Type LoadBalancer
+Change the argocd-server service type to `LoadBalancer`:

-## 4. Login to the server from the CLI
+### Ingress
+Follow the [ingress documentation](ingress.md) on how to configure Argo CD with ingress.
 
-Login with using the `admin` user. The initial password is autogenerated to be the pod name of the
-ArgoCD API server. This can be retrieved with the command:
+### Port Forwarding
+Kubectl port-forwarding can also be used to connect to the API server without exposing the service.
+
+```bash
+kubectl port-forward svc/argocd-server -n argocd 8080:443
 ```
-kubectl get pods -n argocd -l app=argocd-server -o name | cut -d'/' -f 2

-
-On Minikube:
-```
-argocd login $(minikube service argocd-server -n argocd --url | cut -d'/' -f 3) --name minikube
-```
-Other clusters:
-```
-kubectl get svc -n argocd argocd-server
-argocd login <EXTERNAL-IP>

-## 5. Register a cluster to deploy apps to
+## 5. Register a cluster to deploy apps to (optional)
 
-We will now register a cluster to deploy applications to. First list all clusters contexts in your
-kubconfig:
-```
+This step registers a cluster's credentials to Argo CD, and is only necessary when deploying to
+an external cluster. When deploying internally (to the same cluster that Argo CD is running in),
+https://kubernetes.default.svc should be used as the application's K8s API server address.
+
+First list all clusters contexts in your current kubconfig:
+```bash
 argocd cluster add
 ```
 
 Choose a context name from the list and supply it to `argocd cluster add CONTEXTNAME`. For example,
-for minikube context, run:
-```
-argocd cluster add minikube --in-cluster
+for docker-for-desktop context, run:
+```bash
+argocd cluster add docker-for-desktop
 ```
 
-The above command installs an `argocd-manager` ServiceAccount and ClusterRole into the cluster
-associated with the supplied kubectl context. ArgoCD uses the service account token to perform its
-management tasks (i.e. deploy/monitoring).
+The above command installs a ServiceAccount (`argocd-manager`), into the kube-system namespace of 
+that kubectl context, and binds the service account to an admin-level ClusterRole. Argo CD uses this
+service account token to perform its management tasks (i.e. deploy/monitoring).
 
-The `--in-cluster` option indicates that the cluster we are registering, is the same cluster that
-ArgoCD is running in. This allows ArgoCD to connect to the cluster using the internal kubernetes
-hostname (kubernetes.default.svc). When registering a cluster external to ArgoCD, the `--in-cluster`
-flag should be omitted.
+> NOTE: the rules of the `argocd-manager-role` role can be modified such that it only has 
+`create`, `update`, `patch`, `delete` privileges to a limited set of namespaces, groups, kinds.
+However `get`, `list`, `watch` privileges are required at the cluster-scope for Argo CD to function.

+
+## Custom Health Checks
+
+Argo CD supports custom health checks written in [Lua](https://www.lua.org/). This is useful if you:
+
+* Are affected by known issues where your `Ingress` or `StatefulSet` resources are stuck in `Progressing` state because of bug in your resource controller.
+* Have a custom resource for which Argo CD does not have a built-in health check.
+
+There are two ways to configure a custom health check. The next two sections describe those ways.
+
+### Way 1. Define a Custom Health Check in `argocd-cm` ConfigMap
+
+Custom health checks can be defined in `resource.customizations` field of `argocd-cm`. Following example demonstrates a health check for `certmanager.k8s.io/Certificate`.
+
+```yaml
+data:
+  resource.customizations: |
+    certmanager.k8s.io/Certificate:
+      health.lua: |
+        hs = {}
+        if obj.status ~= nil then
+          if obj.status.conditions ~= nil then
+            for i, condition in ipairs(obj.status.conditions) do
+              if condition.type == "Ready" and condition.status == "False" then
+                hs.status = "Degraded"
+                hs.message = condition.message
+                return hs
+              end
+              if condition.type == "Ready" and condition.status == "True" then
+                hs.status = "Healthy"
+                hs.message = condition.message
+                return hs
+              end
+            end
+          end
+        end
+        
+        hs.status = "Progressing"
+        hs.message = "Waiting for certificate"
+        return hs
+```
+The `obj` is a global variable which contains the resource. The script must return an object with status and optional message field.
+
+NOTE: as a security measure you don't have access to most of the standard Lua libraries.
+
+### Way 2. Contribute a Custom Health Check to https://github.com/argoproj/argo-cd
+
+A health check can be bundled into Argo CD. Custom health check scripts are located in the `resource_customizations` directory. This must have the following directory structure:
+
+```
+argo-cd
+|-- resource_customizations
+|    |-- your.crd.group.io               # CRD group
+|    |    |-- MyKind                     # Resource kind
+|    |    |    |-- health.lua            # Health check
+|    |    |    |-- health_test.yaml      # Test inputs and expected results
+|    |    |    +-- testdata              # Directory with test resource YAML definitions
+```
+
+Each health check must have tests defined in `health_test.yaml` file. The `health_test.yaml` is a YAML file with the following structure:
+
+```yaml
+tests:
+- healthStatus:
+    status: ExpectedStatus
+    message: Expected message
+  inputPath: testdata/test-resource-definition.yaml
+```
+
+The [PR#1139](https://github.com/argoproj/argo-cd/pull/1139) is an example of Cert Manager CRDs custom health check.

+# Ingress Configuration
+
+Argo CD runs both a gRPC server (used by the CLI), as well as a HTTP/HTTPS server (used by the UI).
+Both protocols are exposed by the argocd-server service object on the following ports:
+* 443 - gRPC/HTTPS
+* 80 - HTTP (redirects to HTTPS)
+
+There are several ways how Ingress can be configured.
+
+## [kubernetes/ingress-nginx](https://github.com/kubernetes/ingress-nginx)
+
+### Option 1: ssl-passthrough
+
+Because Argo CD serves multiple protocols (gRPC/HTTPS) on the same port (443), this provides a
+challenge when attempting to define a single nginx ingress object and rule for the argocd-service,
+since the `nginx.ingress.kubernetes.io/backend-protocol` [annotation](https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/annotations/#backend-protocol)
+accepts only a single value for the backend protocol (e.g. HTTP, HTTPS, GRPC, GRPCS).
+
+In order to expose the Argo CD API server with a single ingress rule and hostname, the
+`nginx.ingress.kubernetes.io/ssl-passthrough` [annotation](https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/annotations/#ssl-passthrough)
+must be used to passthrough TLS connections and terminate TLS at the Argo CD API server.
+
+```yaml
+apiVersion: extensions/v1beta1
+kind: Ingress
+metadata:
+  name: argocd-server-ingress
+  annotations:
+    kubernetes.io/ingress.class: nginx
+    nginx.ingress.kubernetes.io/force-ssl-redirect: "true"
+    nginx.ingress.kubernetes.io/ssl-passthrough: "true"
+spec:
+  rules:
+  - host: argocd.example.com
+    http:
+      paths:
+      - backend:
+          serviceName: argocd-server
+          servicePort: https
+```
+
+The above rule terminates TLS at the Argo CD API server, which detects the protocol being used,
+and responds appropriately. Note that the `nginx.ingress.kubernetes.io/ssl-passthrough` annotation
+requires that the `--enable-ssl-passthrough` flag be added to the command line arguments to
+`nginx-ingress-controller`.
+
+### Option 2: Multiple ingress objects and hosts
+
+Since ingress-nginx Ingress supports only a single protocol per Ingress object, an alternative
+way would be to define two Ingress objects. One for HTTP/HTTPS, and the other for gRPC:
+
+HTTP/HTTPS Ingress:
+```yaml
+apiVersion: extensions/v1beta1
+kind: Ingress
+metadata:
+  name: argocd-server-http-ingress
+  annotations:
+    kubernetes.io/ingress.class: "nginx"
+    nginx.ingress.kubernetes.io/force-ssl-redirect: "true"
+    nginx.ingress.kubernetes.io/backend-protocol: "HTTP"
+spec:
+  rules:
+  - http:
+      paths:
+      - backend:
+          serviceName: argocd-server
+          servicePort: http
+    host: argocd.example.com
+  tls:
+  - hosts:
+    - argocd.example.com
+    secretName: argocd-secret
+```
+
+gRPC Ingress:
+```yaml
+apiVersion: extensions/v1beta1
+kind: Ingress
+metadata:
+  name: argocd-server-grpc-ingress
+  annotations:
+    kubernetes.io/ingress.class: "nginx"
+    nginx.ingress.kubernetes.io/backend-protocol: "GRPC"
+spec:
+  rules:
+  - http:
+      paths:
+      - backend:
+          serviceName: argocd-server
+          servicePort: https
+    host: grpc.argocd.example.com
+  tls:
+  - hosts:
+    - grpc.argocd.example.com
+    secretName: argocd-secret
+```
+
+The API server should then be run with TLS disabled. Edit the `argocd-server` deployment to add the
+`--insecure` flag to the argocd-server command:
+
+```yaml
+spec:
+  template:
+    spec:
+      name: argocd-server
+      containers:
+      - command:
+        - /argocd-server
+        - --staticassets
+        - /shared/app
+        - --repo-server
+        - argocd-repo-server:8081
+        - --insecure
+```
+
+The obvious disadvantage to this approach is that this technique require two separate hostnames for
+the API server -- one for gRPC and the other for HTTP/HTTPS. However it allow TLS termination to
+happen at the ingress controller.
+
+
+## AWS Application Load Balancers (ALBs) and Classic ELB (HTTP mode)
+
+Neither ALBs and Classic ELB in HTTP mode, do not have full support for HTTP2/gRPC which is the
+protocol used by the `argocd` CLI. Thus, when using an AWS load balancer, either Classic ELB in
+passthrough mode is needed, or NLBs.
+
+
+## UI base path
+
+If Argo CD UI is available under non-root path (e.g. `/argo-cd` instead of `/`) then UI path should be configured in API server.
+To configure UI path add `--basehref` flag into `argocd-server` deployment command:
+
+```yaml
+spec:
+  template:
+    spec:
+      name: argocd-server
+      containers:
+      - command:
+        - /argocd-server
+        - --staticassets
+        - /shared/app
+        - --repo-server
+        - argocd-repo-server:8081
+        - --basehref
+        - /argo-cd
+```
+
+NOTE: flag `--basehref` only changes UI base URL. API server keep using `/` path so you need to add URL rewrite rule to proxy config.
+Example nginx.conf with URL rewrite:
+
+```
+worker_processes 1;
+
+events { worker_connections 1024; }
+
+http {
+
+    sendfile on;
+
+    server {
+        listen 443;
+
+        location /argo-cd {
+            rewrite /argo-cd/(.*) /$1  break;
+            proxy_pass         https://localhost:8080;
+            proxy_redirect     off;
+            proxy_set_header   Host $host;
+            proxy_set_header   X-Real-IP $remote_addr;
+            proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
+            proxy_set_header   X-Forwarded-Host $server_name;
+        }

+## Projects
+
+Projects provide a logical grouping of applications, which is useful when Argo CD is used by multiple
+teams. Projects provide the following features:
+
+* restrict *what* may be deployed (trusted git source repositories)
+* restrict *where* apps may be deployed to (destination clusters and namespaces)
+* restrict what kinds of objects may or may not be deployed (e.g. RBAC, CRDs, DaemonSets, NetworkPolicy etc...)
+* defining project roles to provide application RBAC (bound to OIDC groups and/or JWT tokens)
+
+### The default project
+
+Every application belongs to a single project. If unspecified, an application belongs to the
+`default` project, which is created automatically and by default, permits deployments from any
+source repo, to any cluster, and all resource Kinds. The default project can be modified, but not
+deleted. When initially created, it's specification is configured to be the most permissive:
+
+```yaml
+spec:
+  sourceRepos:
+  - '*'
+  destinations:
+  - namespace: '*'
+    server: '*'
+  clusterResourceWhitelist:
+  - group: '*'
+    kind: '*'
+```
+
+### Creating Projects
+
+Additional projects can be created to give separate teams different levels of access to namespaces.
+The following command creates a new project `myproject` which can deploy applications to namespace
+`mynamespace` of cluster `https://kubernetes.default.svc`. The permitted git source repository is
+set to `https://github.com/argoproj/argocd-example-apps.git` repository.
+
+```
+argocd proj create myproject -d https://kubernetes.default.svc,mynamespace -s https://github.com/argoproj/argocd-example-apps.git
+```
+
+### Managing Projects
+
+Permitted source git repositories are managed using commands:
+
+```bash
+argocd proj add-source <PROJECT> <REPO>
+argocd proj remove-source <PROJECT> <REPO>
+```
+
+Permitted destination clusters and namespaces are managed with the commands:
+```
+argocd proj add-destination <PROJECT> <CLUSTER>,<NAMESPACE>
+argocd proj remove-destination <PROJECT> <CLUSTER>,<NAMESPACE>
+```
+
+Permitted destination K8s resource kinds are managed with the commands. Note that namespaced-scoped
+resources are restricted via a blacklist, whereas cluster-scoped resources are restricted via
+whitelist.
+```
+argocd proj allow-cluster-resource <PROJECT> <GROUP> <KIND>
+argocd proj allow-namespace-resource <PROJECT> <GROUP> <KIND>
+argocd proj deny-cluster-resource <PROJECT> <GROUP> <KIND>
+argocd proj deny-namespace-resource <PROJECT> <GROUP> <KIND>
+```
+
+### Assign application to a project
+
+The application project can be changed using `app set` command. In order to change the project of
+an app, the user must have permissions to access the new project.
+
+```
+argocd app set guestbook-default --project myproject
+```
+
+### Configuring RBAC with projects
+
+Once projects have been defined, RBAC rules can be written to restrict access to the applications
+in the project. The following example configures RBAC for two GitHub teams: `team1` and `team2`,
+both in the GitHub org, `some-github-org`. There are two projects, `project-a` and `project-b`.
+`team1` can only manage applications in `project-a`, while `team2` can only manage applications in
+`project-b`. Both `team1` and `team2` have the ability to manage repositories.

+## Project Roles
+
+Projects include a feature called roles that enable automated access to a project's applications.
+These can be used to give a CI pipeline a restricted set of permissions. For example, a CI system
+may only be able to sync a single app (but not change its source or destination).
+
+Projects can have multiple roles, and those roles can have different access granted to them. These
+permissions are called policies, and they are stored within the role as a list of policy strings.
+A role's policy can only grant access to that role and are limited to applications within the role's
+project.  However, the policies have an option for granting wildcard access to any application
+within a project.
+
+In order to create roles in a project and add policies to a role, a user will need permission to
+update a project.  The following commands can be used to manage a role.
+
+```bash
+argocd proj role list
+argocd proj role get
+argocd proj role create
+argocd proj role delete
+argocd proj role add-policy
+argocd proj role remove-policy
+```
+
+Project roles in itself are not useful without generating a token to associate to that role. Argo CD
+supports JWT tokens as the means to authenticate to a role. Since the JWT token is
+associated with a role's policies, any changes to the role's policies will immediately take effect
+for that JWT token.
+
+The following commands are used to manage the JWT tokens.
+
+```bash
+argocd proj role create-token PROJECT ROLE-NAME
+argocd proj role delete-token PROJECT ROLE-NAME ISSUED-AT
+```
+
+Since the JWT tokens aren't stored in Argo CD, they can only be retrieved when they are created. A
+user can leverage them in the cli by either passing them in using the `--auth-token` flag or setting
+the ARGOCD_AUTH_TOKEN environment variable. The JWT tokens can be used until they expire or are
+revoked.  The JWT tokens can created with or without an expiration, but the default on the cli is
+creates them without an expirations date.  Even if a token has not expired, it cannot be used if
+the token has been revoked.
+
+Below is an example of leveraging a JWT token to access a guestbook application.  It makes the
+assumption that the user already has a project named myproject and an application called
+guestbook-default.
+
+```bash
+PROJ=myproject
+APP=guestbook-default
+ROLE=get-role
+argocd proj role create $PROJ $ROLE
+argocd proj role create-token $PROJ $ROLE -e 10m
+JWT=<value from command above>
+argocd proj role list $PROJ
+argocd proj role get $PROJ $ROLE
+
+# This command will fail because the JWT Token associated with the project role does not have a policy to allow access to the application
+argocd app get $APP --auth-token $JWT
+# Adding a policy to grant access to the application for the new role
+argocd proj role add-policy $PROJ $ROLE --action get --permission allow --object $APP
+argocd app get $PROJ-$ROLE --auth-token $JWT
+
+# Removing the policy we added and adding one with a wildcard.
+argocd proj role remove-policy $PROJ $TOKEN -a get -o $PROJ-$TOKEN
+argocd proj role remove-policy $PROJ $TOKEN -a get -o '*'
+# The wildcard allows us to access the application due to the wildcard.
+argocd app get $PROJ-$TOKEN --auth-token $JWT
+argocd proj role get $PROJ
+
+
+argocd proj role get $PROJ $ROLE
+# Revoking the JWT token
+argocd proj role delete-token $PROJ $ROLE <id field from the last command>

 ## Overview
 
-The feature RBAC allows restricting access to ArgoCD resources. ArgoCD does not have own user management system and has only one built-in user `admin`. The `admin` user is a
-superuser and it has full access. RBAC requires configuring [SSO](./sso.md) integration. Once [SSO](./sso.md) is connected you can define RBAC roles and map roles to groups.
+The RBAC feature enables restriction of access to Argo CD resources. Argo CD does not have its own
+user management system and has only one built-in user `admin`. The `admin` user is a superuser and
+it has unrestricted access to the system. RBAC requires [SSO configuration](./sso.md). Once SSO is
+configured, additional RBAC roles can be defined, and SSO groups can man be mapped to roles.
 
 ## Configure RBAC
 
-RBAC configuration allows defining roles and groups. ArgoCD has two pre-defined roles: role `role:readonly` which provides read-only access to all resources and role `role:admin`
-which provides full access. Role definitions are available in [builtin-policy.csv](../util/rbac/builtin-policy.csv) file.
+RBAC configuration allows defining roles and groups. Argo CD has two pre-defined roles:
+* `role:readonly` - read-only access to all resources
+* `role:admin` - unrestricted access to all resources
+These role definitions can be seen in [builtin-policy.csv](../assets/builtin-policy.csv)
 
-Additional roles and groups can be configured in `argocd-rbac-cm` ConfigMap. The example below custom role `org-admin`. The role is assigned to any user which belongs to
-`your-github-org:your-team` group. All other users get `role:readonly` and cannot modify ArgoCD settings.

-## Configure Projects
-
-Argo projects allow grouping applications which is useful if ArgoCD is used by multiple teams. Additionally, projects restrict source repositories and destination
-Kubernetes clusters which can be used by applications belonging to the project.
-
-### 1. Create new project
-
-Following command creates project `myproject` which can deploy applications to namespace `default` of cluster `https://kubernetes.default.svc`. The valid application source is defined in the `https://github.com/argoproj/argocd-example-apps.git` repository.
-
-```
-argocd proj create myproject -d https://kubernetes.default.svc,default -s https://github.com/argoproj/argocd-example-apps.git
-```
-
-Project sources and destinations can be managed using commands
-```
-argocd project add-destination
-argocd project remove-destination
-argocd project add-source
-argocd project remove-source
-```
-
-### 2. Assign application to a project
-
-Each application belongs to a project. By default, all application belongs to the default project which provides access to any source repo/cluster. The application project can be
-changes using `app set` command:
-
-```
-argocd app set guestbook-default --project myproject
-```
-
-### 3. Update RBAC rules
-
-Following example configure admin access for two teams. Each team has access only two application of one project (`team1` can access `default` project and `team2` can access
-`myproject` project).
-

+# Security
+
+Argo CD has undergone rigourous internal security reviews and penetration testing to satisfy [PCI
+compliance](https://www.pcisecuritystandards.org) requirements. The following are some security
+topics and implementation details of Argo CD.
+
+
+## Authentication
+
+Authentication to Argo CD API server is performed exclusively using [JSON Web Tokens](https://jwt.io)
+(JWTs). Username/password bearer tokens are not used for authentication. The JWT is obtained/managed
+in one of the following ways:
+
+1. For the local `admin` user, a username/password is exchanged for a JWT using the `/api/v1/session`
+   endpoint. This token is signed & issued by the Argo CD API server itself, and has no expiration.
+   When the admin password is updated, all existing admin JWT tokens are immediately revoked.
+   The password is stored as a bcrypt hash in the [`argocd-secret`](../manifests/base/argocd-secret.yaml) Secret.
+
+2. For Single Sign-On users, the user completes an OAuth2 login flow to the configured OIDC identity
+   provider (either delegated through the bundled Dex provider, or directly to a self-managed OIDC
+   provider). This JWT is signed & issued by the IDP, and expiration and revokation is handled by
+   the provider. Dex tokens expire after 24 hours.
+
+3. Automation tokens are generated for a project using the `/api/v1/projects/{project}/roles/{role}/token`
+   endpoint, and are signed & issued by Argo CD. These tokens are limited in scope and privilege,
+   and can only be used to manage application resources in the project which it belongs to. Project
+   JWTs have a configurable expiration and can be immediately revoked by deleting the JWT reference
+   ID from the project role.
+
+
+## Authorization
+
+Authorization is performed by iterating the list of group membership in a user's JWT groups claims,
+and comparing each group against the roles/rules in the [RBAC](rbac.md) policy. Any matched rule
+permits access to the API request.
+
+
+## TLS
+
+All network communication is performed over TLS including service-to-service communication between
+the three components (argocd-server, argocd-repo-server, argocd-application-controller). The Argo CD
+API server can enforce the use of TLS 1.2 using the flag: `--tlsminversion 1.2`.
+
+
+## Sensitive Information
+
+### Secrets
+
+Argo CD never returns sensitive data from its API, and redacts all sensitive data in API payloads
+and logs. This includes:
+* cluster credentials
+* git credentials
+* OAuth2 client secrets
+* Kubernetes Secret values
+
+### External Cluster Credentials
+
+To manage external clusters, Argo CD stores the credentials of the external cluster as a Kubernetes
+Secret in the argocd namespace. This secret contains the K8s API bearer token associated with the
+`argocd-manager` ServiceAccount created during `argocd cluster add`, along with connection options
+to that API server (TLS configuration/certs, aws-iam-authenticator RoleARN, etc...).
+The information is used to reconstruct a REST config and kubeconfig to the cluster used by Argo CD
+services.
+
+To rotate the bearer token used by Argo CD, the token can be deleted (e.g. using kubectl) which
+causes kuberentes to generate a new secret with a new bearer token. The new token can be re-inputted
+to Argo CD by re-running `argocd cluster add`. Run the following commands against the *_managed_*
+cluster:
+
+```bash
+# run using a kubeconfig for the externally managed cluster
+kubectl delete secret argocd-manager-token-XXXXXX -n kube-system
+argocd cluster add CONTEXTNAME
+```
+
+To revoke Argo CD's access to a managed cluster, delete the RBAC artifacts against the *_managed_*
+cluster, and remove the cluster entry from Argo CD:
+
+```bash
+# run using a kubeconfig for the externally managed cluster
+kubectl delete sa argocd-manager -n kube-system 
+kubectl delete clusterrole argocd-manager-role
+kubectl delete clusterrolebinding argocd-manager-role-binding
+argocd cluster rm https://your-kubernetes-cluster-addr
+```
+
+> NOTE: for AWS EKS clusters, [aws-iam-authenticator](https://github.com/kubernetes-sigs/aws-iam-authenticator)
+  is used to authenticate to the external cluster, which uses IAM roles in lieu of locally stored
+  tokens, so token rotation is not needed, and revokation is handled through IAM.
+
+## Cluster RBAC
+
+By default, Argo CD uses a [clusteradmin level role](../manifests/cluster-install/application-controller/argocd-application-controller-clusterrole.yaml)
+in order to:
+1. watch & operate on cluster state
+2. deploy resources to the cluster
+
+Although Argo CD requires cluster-wide **_read_** privileges to resources in the managed cluster to
+function properly, it does not necessarily need full **_write_** privileges to the cluster. The
+ClusterRole used by argocd-server and argocd-application-controller can be modified such
+that write privileges are limited to only the namespaces and resources that you wish Argo CD to
+manage.
+
+To fine-tune privileges of externally managed clusters, edit the ClusterRole of the `argocd-manager-role`
+
+```bash
+# run using a kubeconfig for the externally managed cluster
+kubectl edit clusterrole argocd-manager-role
+```
+
+To fine-tune privileges which Argo CD has against its own cluster (i.e. https://kubernetes.default.svc),
+edit the following cluster roles where Argo CD is running in:
+
+```bash
+# run using a kubeconfig to the cluster Argo CD is running in
+kubectl edit clusterrole argocd-server
+kubectl edit clusterrole argocd-application-controller
+```
+
+Note:
+
+* If you to deny ArgoCD access to a kind of resource then add it as an [excluded resource](declarative-setup.md#resource-exclusion). 
+
+## Auditing
+
+As a GitOps deployment tool, the git commit history provides a natural audit log of what changes
+were made to application configuration, when they were made, and by whom. However, this audit log
+only applies to what happened in git and does not necessarily correlate one-to-one with events
+that happen in a cluster. For example, User A could have made multiple commits to application
+manifests, but User B could have just only synced those changes to the cluster sometime later.
+
+To complement the git revision history, Argo CD emits Kubernetes Events of application activity,
+indicating the responsible actor when applicable. For example:
+
+```bash
+$ kubectl get events
+LAST SEEN   FIRST SEEN   COUNT   NAME                         KIND          SUBOBJECT   TYPE      REASON               SOURCE                          MESSAGE

+
+
+## WebHook Payloads
+
+Payloads from webhook events are considered untrusted. Argo CD only examines the payload to infer
+the involved applications of the webhook event (e.g. which repo was modified), then refreshes
+the related application for reconciliation. This refresh is the same refresh which occurs regularly
+at three minute intervals, just fast-tracked by the webhook event.

+Argo CD polls git repositories every three minutes to detect changes to the manifests. To eliminate
+this delay from polling, the API server can be configured to receive webhook events. Argo CD supports
 git webhook notifications from GitHub, GitLab, and BitBucket. The following explains how to configure
 a git webhook for GitHub, but the same process should be applicable to other providers.
 
 ### 1. Create the webhook in the git provider
 
 In your git provider, navigate to the settings page where webhooks can be configured. The payload
-URL configured in the git provider should use the /api/webhook endpoint of your ArgoCD instance

+application (a process which already occurs at three-minute intervals). If Argo CD is publicly

+# Argo CD Installation Manifests
+
+Two sets of installation manifests are provided:
+
+* [install.yaml](install.yaml) - Standard Argo CD installation with cluster-admin access. Use this
+  manifest set if you plan to use Argo CD to deploy applications in the same cluster that Argo CD runs
+  in (i.e. kubernetes.svc.default). Will still be able to deploy to external clusters with inputted
+  credentials.
+
+* [namespace-install.yaml](namespace-install.yaml) - Installation of Argo CD which requires only
+  namespace level privileges (does not need cluster roles). Use this manifest set if you do not
+  need Argo CD to deploy applications in the same cluster that Argo CD runs in, and will rely solely
+  on inputted cluster credentials. An example of using this set of manifests is if you run several
+  Argo CD instances for different teams, where each instance will bedeploying applications to
+  external clusters. Will still be possible to deploy to the same cluster (kubernetes.svc.default)
+  with inputted credentials (i.e. `argocd cluster add <CONTEXT> --in-cluster`).
