GitOps the Hard Way, with Argo CD

Deploying the Helm Chart With Argo CD

Now that we have a Helm chart for the todo app, we point the existing Application at it. The Application name does not change, so updating the manifest and re-applying it switches the source from plain manifests to the Helm chart in place. No need to delete anything.

cat < $HOME/todo/app/manifests/app-helm.yaml
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: todo-app
  namespace: argocd
spec:
  destination:
    namespace: default
    server: https://kubernetes.default.svc
  project: default
  source:
    repoURL: $GITLAB_URL
    targetRevision
