+# Security Policy for Argo CD
+
+Version: **v1.4 (2022-01-23)**
+
+## Preface
+
+As a deployment tool, Argo CD needs to have production access which makes
+security a very important topic. The Argoproj team takes security very
+seriously and is continuously working on improving it.
+
+## A word about security scanners
+
+Many organisations these days employ security scanners to validate their
+container images before letting them on their clusters, and that is a good
+thing. However, the quality and results of these scanners vary greatly,
+many of them produce false positives and require people to look at the
+issues reported and validate them for correctness. A great example of that
+is, that some scanners report kernel vulnerabilities for container images
+just because they are derived from some distribution.
+
+We kindly ask you to not raise issues or contact us regarding any issues
+that are found by your security scanner. Many of those produce a lot of false
+positives, and many of these issues don't affect Argo CD. We do have scanners
+in place for our code, dependencies and container images that we publish. We
+are well aware of the issues that may affect Argo CD and are constantly
+working on the remediation of those that affect Argo CD and our users.
+
+If you believe that we might have missed an issue that we should take a look
+at (that can happen), then please discuss it with us. If there is a CVE
+assigned to the issue, please do open an issue on our GitHub tracker instead
+of writing to the security contact e-mail, since things reported by scanners
+are public already and the discussion that might emerge is of benefit to the
+general community. However, please validate your scanner results and its
+impact on Argo CD before opening an issue at least roughly.
+
+## Supported Versions
+
+We currently support the most recent release (`N`, e.g. `1.8`) and the release
+previous to the most recent one (`N-1`, e.g. `1.7`). With the release of
+`N+1`, `N-1` drops out of support and `N` becomes `N-1`.
+
+We regularly perform patch releases (e.g. `1.8.5` and `1.7.12`) for the
+supported versions, which will contain fixes for security vulnerabilities and
+important bugs. Prior releases might receive critical security fixes on a best
+effort basis, however, it cannot be guaranteed that security fixes get
+back-ported to these unsupported versions.
+
+In rare cases, where a security fix needs complex re-design of a feature or is
+otherwise very intrusive, and there's a workaround available, we may decide to
+provide a forward-fix only, e.g. to be released the next minor release, instead
+of releasing it within a patch branch for the currently supported releases.
+
+## Reporting a Vulnerability
+
+If you find a security related bug in ArgoCD, we kindly ask you for responsible
+disclosure and for giving us appropriate time to react, analyze and develop a
+fix to mitigate the found security vulnerability.
+
+We will do our best to react quickly on your inquiry, and to coordinate a fix
+and disclosure with you. Sometimes, it might take a little longer for us to
+react (e.g. out of office conditions), so please bear with us in these cases.
+
+We will publish security advisories using the
+[Git Hub Security Advisories](https://github.com/argoproj/argo-cd/security/advisories)
+feature to keep our community well informed, and will credit you for your
+findings (unless you prefer to stay anonymous, of course).

+# How the Cluster Decision Resource generator works for clusterDecisionResource
+1. The Cluster Decision Resource generator reads a configurable status format:
+```yaml
+status:
+  clusters:
+  - name: cluster-01
+  - name: cluster-02
+```
+This is a common status format.  Another format that could be read looks like this:
+```yaml
+status:
+  decisions:
+  - clusterName: cluster-01
+    namespace: cluster-01
+  - clusterName: cluster-02
+    namespace: cluster-02
+```
+2. Any resource that has a list of key / value pairs, where the value matches ArgoCD cluster names can be used.
+3. The key / value pairs found in each element of the list will be available to the template. As well, `name` and `server` will still be available to the template.
+4. The Service Account used by the ApplicationSet controller must have access to `Get` the resource you want to retrieve the duck type definition from
+5. A configMap is used to identify the resource to read status of generated ArgoCD clusters from. You can use multiple resources by creating a ConfigMap for each one in the ArgoCD namespace.
+```yaml
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: my-configmap
+data:
+  apiVersion: group.io/v1
+  kind: mykinds
+  statusListKey: clusters
+  matchKey: name
+```
+  * `apiVersion`    - This is the apiVersion of your resource
+  * `kind`          - This is the plural kind of your resource
+  * `statusListKey` - Default is 'clusters', this is the key found in your resource's status that is a list of ArgoCD clusters.
+  * `matchKey`      - Is the key name found in the cluster list, `name` and `clusterName` are the keys in the examples above.
+
+# Applying the example
+1. Connect to a cluster with the ApplicationSet controller running
+2. Edit the Role for the ApplicationSet service account, and grant it permission to `list` the `placementdecisions` resources, from apiGroups `cluster.open-cluster-management.io/v1alpha1`
+```yaml
+- apiGroups:
+  - "cluster.open-cluster-management.io/v1alpha1"
+  resources:
+  - placementdecisions
+  verbs:
+  - list
+```
+3. Apply the following controller and associated ManagedCluster CRD's:
+https://github.com/open-cluster-management/placement
+4. Now apply the PlacementDecision and an ApplicationSet:
+```bash
+kubectl apply -f ./placementdecision.yaml
+kubectl apply -f ./configMap.yaml
+kubectl apply -f ./ducktype-example.yaml
+```
+5. For now this won't do anything until you create a controller that populates the `Status.Decisions` array.
