Add Repository to Argo CD

To deploy applications with Argo CD we need to connect Repositories. This is also useful if you want to give developers a way to deploy their applications onto your platform without much intervention on your side.

An Argo CD App Repository is a logical concept to control where applications may be deployed from. For more information check: https://argo-cd.readthedocs.io/en/stable/user-guide/private-repositories/

Add credentials to vault

Add the repository credentials to your vault. This can be a password or a PAT.

{
  "repo_pat": {
    "pat": "<the kubeconfig>"
  }
}

Modify Argo CD overlays

Add the following to your argo-cd/values.yaml.

repositories:
    - name: user-repo-mock
      projectScope: k8s-worker-0
      # # This points to the secret in vault
      remoteRef:
        remoteKey: repo_pat
        remoteKeyProperty: pat
      repoType: git
      secretStoreRef:
        kind: ClusterSecretStore
        name: controlplane-0-production
      url: <the repo url you want to add>
      username: <the username for connection. also needed for PAT>

That whats happening behind the scenes:

Push your changes to git

Do not forget to push your changes to the git repository that serves your Argo CD application. If you let Argo CD manage itself, it will add the configured repository to your cluster.
