 * A Kubernetes cluster. You won't need a fully blown multi-master, multi-node cluster, but you will need something like K3S, Minikube or microk8s. You will also need a working Kubernetes client (`kubectl`) configuration in your development environment. The configuration must reside in `~/.kube/config` and the API server URL must point to the IP address of your local machine (or VM), and **not** to `localhost` or `127.0.0.1` if you are using the virtualized development toolchain (see below)
 
-* You will also need a working Docker runtime environment, to be able to build and run images.
-The Docker version must be fairly recent, and support multi-stage builds. You should not work as root. Make your local user a member of the `docker` group to be able to control the Docker service on your machine.

+## Limiting Directory App Memory Usage
+
+> >2.2.10, 2.1.16, >2.3.5
+
+Directory-type Applications (those whose source is raw JSON or YAML files) can consume significant
+[repo-server](architecture.md#repository-server) memory, depending on the size and structure of the YAML files.
+
+To avoid over-using memory in the repo-server (potentially causing a crash and denial of service), set the
+`reposerver.max.combined.directory.manifests.size` config option in [argocd-cmd-params-cm](argocd-cmd-params-cm.yaml).
+
+This option limits the combined size of all JSON or YAML files in an individual app. Note that the in-memory
+representation of a manifest may be as much as 300x the size of the manifest on disk. Also note that the limit is per
+Application. If manifests are generated for multiple applications at once, memory usage will be higher.
+
+**Example:**
+
+Suppose your repo-server has a 10G memory limit, and you have ten Applications which use raw JSON or YAML files. To
+calculate the max safe combined file size per Application, divide 10G by 300 * 10 Apps (300 being the worst-case memory
+growth factor for the manifests).
+
+```
+10G / 300 * 10 = 3M
+```
+
+So a reasonably safe configuration for this setup would be a 3M limit per app.
+
+```yaml
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: argocd-cmd-params-cm
+data:
+  reposerver.max.combined.directory.manifests.size: '3M'
+```
+
+The 300x ratio assumes a maliciously-crafted manifest file. If you only want to protect against accidental excessive
+memory use, it is probably safe to use a smaller ratio.
+
+Keep in mind that if a malicious user can create additional Applications, they can increase the total memory usage.
+Grant [App creation privileges](rbac.md) carefully.

+## Support for private repo SSH keys using the SHA-1 signature hash algorithm is removed in 2.2.12
+
+Argo CD 2.2.12 upgraded its base image from Ubuntu 21.10 to Ubuntu 22.04, which upgraded OpenSSH to 8.9. OpenSSH starting
+with 8.8 [dropped support for the `ssh-rsa` SHA-1 key signature algorithm](https://www.openssh.com/txt/release-8.8).
+
+The signature algorithm is _not_ the same as the algorithm used when generating the key. There is no need to update
+keys.
+
+The signature algorithm is negotiated with the SSH server when the connection is being set up. The client offers its
+list of accepted signature algorithms, and if the server has a match, the connection proceeds. For most SSH servers on
+up-to-date git providers, acceptable algorithms other than `ssh-rsa` should be available.
+
+Before upgrading to Argo CD 2.2.12, check whether your git provider(s) using SSH authentication support algorithms newer
+than `rsa-ssh`.
+
+1. Make sure your version of SSH >= 8.9 (the version used by Argo CD). If not, upgrade it before proceeding.
+
+   ```shell
+   ssh -V
+   ```
+
+   Example output: `OpenSSH_8.9p1 Ubuntu-3, OpenSSL 3.0.2 15 Mar 2022`
+
+2. Once you have a recent version of OpenSSH, follow the directions from the [OpenSSH 8.8 release notes](https://www.openssh.com/txt/release-8.7):

+   > To check whether a server is using the weak ssh-rsa public key
+   > algorithm, for host authentication, try to connect to it after

+   > ```
+   >
+   > If the host key verification fails and no other supported host key
+   > types are available, the server software on that host should be
+   > upgraded.
+
+   If the server does not support an acceptable version, you will get an error similar to this;
+
+   ```
+   $ ssh -oHostKeyAlgorithms=-ssh-rsa vs-ssh.visualstudio.com
+   Unable to negotiate with 20.42.134.1 port 22: no matching host key type found. Their offer: ssh-rsa
+   ```
+
+   This indicates that the server needs to update its supported key signature algorithms, and Argo CD will not connect
+   to it.
+
+### Workaround
+
+The [OpenSSH 8.8 release notes](https://www.openssh.com/txt/release-8.8) describe a workaround if you cannot change the
+server's key signature algorithms configuration.
+
+> Incompatibility is more likely when connecting to older SSH
+> implementations that have not been upgraded or have not closely tracked
+> improvements in the SSH protocol. For these cases, it may be necessary
+> to selectively re-enable RSA/SHA1 to allow connection and/or user
+> authentication via the HostkeyAlgorithms and PubkeyAcceptedAlgorithms
+> options. For example, the following stanza in ~/.ssh/config will enable
+> RSA/SHA1 for host and user authentication for a single destination host:
+>
+> ```
+> Host old-host
+>     HostkeyAlgorithms +ssh-rsa
+>     PubkeyAcceptedAlgorithms +ssh-rsa
+> ```
+>
+> We recommend enabling RSA/SHA1 only as a stopgap measure until legacy
+> implementations can be upgraded or reconfigured with another key type
+> (such as ECDSA or Ed25519).
+
+To apply this to Argo CD, you could create a ConfigMap with the desired ssh config file and then mount it at
+`/home/argocd/.ssh/config`.

+### Skipping certificate verification on OIDC provider connections
+
+By default, all connections made by the API server to OIDC providers (either external providers or the bundled Dex
+instance) must pass certificate validation. These connections occur when getting the OIDC provider's well-known
+configuration, when getting the OIDC provider's keys, and  when exchanging an authorization code or verifying an ID

+
+Disabling certificate verification might make sense if:

+  **and** you understand and accept the risks of skipping OIDC provider cert verification.
+* You are using an external OIDC provider **and** that provider uses an invalid certificate **and** you cannot solve
+  the problem by setting `oidcConfig.rootCA` **and** you understand and accept the risks of skipping OIDC provider cert

+
+If either of those two applies, then you can disable OIDC provider certificate verification by setting

 ```
 
 The example above shows how an ArgoCD Application can be configured so it will ignore the `spec.replicas` field from the desired state (git) during the sync stage. This is achieve by calculating and pre-patching the desired state before applying it in the cluster. Note that the `RespectIgnoreDifferences` sync option is only effective when the resource is already created in the cluster. If the Application is being created and no live state exists, the desired state is applied as-is.

+kind: Application
+metadata:
+  namespace: test
+spec:

+```
+The example above shows how an Argo CD Application can be configured so it will create namespaces for the Application resources if the namespaces don't exist already. Without this either declared in the Application manifest or passed in the cli via `--sync-option CreateNamespace=true`, the Application will fail to sync if the resources' namespaces do not exist.
