Policy Collection
A collection of policy examples for Open Cluster Management
Repo structure
This repo 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; you will use the forked version of this repo 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 repo, you can pull the latest changes from policy-collection to your own repo through a pull request. Any further changes to your repo will 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.
