Policy Collection

A collection of policy examples for Open Cluster Management.

NOTE: The master branch is deprecated in favor of main as the primary branch, and is expected to be removed after May 31, 2021. Be sure to update any configurations or subscriptions accordingly.

Repository structure

This repository hosts policies for Open Cluster Management. You can find policies from the following folders:

• stable -- Policies in the stable folder can be applied with Red Hat Advanced Cluster Management for Kubernetes.
• community -- Policies in the community folder are contributed from the open source community and can be applied with the product governance framework.

Using GitOps to deploy policies to a cluster

Fork this repository and use the forked version as the target to run the sync against. This is to avoid unintended changes to be applied to your cluster automatically. To get latest policies from the policy-collection repository, you can pull the latest changes from policy-collection to your own repository through a pull request. Any further changes to your repository are automatically be applied to your cluster.

Make sure you have kubectl installed and that you are logged into your hub cluster in terminal.

Run kubectl create ns policies to create a "policies" ns on hub. If you prefer to call the namespace something else, you can run kubectl create ns <custom ns> instead.

From within this directory in terminal, run cd deploy to access the deployment directory, then run bash ./deploy.sh -u <url> -p <path> -n <namespace>. (Details on all of the parameters for this command can be viewed in its README.)

The policies are applied to all managed clusters that are available, and have the environement set to dev. Specifically, an available managed cluster has the status parameter set to true by the system, for the ManagedClusterConditionAvailable condition. If policies need to be applied to another set of clusters, update the PlacementRule.spec.clusterSelector.matchExpressions section in the policies.

Note: As new clusters are added that fit the critieria previously mentioned, the policies are applied automatically.
