Add namespace to cluster

Prerequisites

• sops 3.6+
• imported aicoe-sre gpg key

Instructions

Namespaces are added to ArgoCD by altering the corresponding cluster spec. Cluster specs are defined within the clusters folder.

Open the file in the sops editor, for example if updating the cluster spec apps.ocp.prod.psi.redhat.com.enc.yaml you would execute:

# From repo root
$ cd manifests/overlays/prod/resources/secrets/clusters
$ sops apps.ocp.prod.psi.redhat.com.enc.yaml

This should open the decrypted form of the cluster spec. Update the namespace field by appending your namespace (comma-separated, no spaces, if there are multiple namespaces).

...
 10 stringData:
 11     name: apps.ocp.prod.psi.redhat.com
 12     config: ...
 14     namespaces: namespace-1,namespace-2 # Update this field by appending the new namespace
 15     server: ...

Once done, submit a PR with this change.

If your cluster isn't there then it will need to be added by a member of the aicoe-sre team. See here for more info.
