argocd auto sync policy - using selfHeal as an example

In my example, I am going to sync my git source code to kubernetes cluster. Whenever i push my changes, this trigger a deployment in 180s (3 minutes - default) This can be done via selfHeal as shown below:-

apiVersion: argoproj.io/v1alpha1

kind: Application

metadata:

  name: helm-guestbook

  namespace: argocd

spec:

  syncPolicy:

     automated:

       selfHeal: true

  project: default

  # directory:

  #     recurse: true

  source:

    repoURL: https://github.com/mitzenjeremywoo/argocd-example-apps.git

    path: helm-guestbook

    helm:

      releaseName: helm-guestbook

      valueFiles:

      - values-production.yaml     

  destination:

    server: "https://kubernetes.default.svc"

    namespace: default

To change the default sync you can edit argocd-cm in the argocd namespace. Refer to the link here for more information.

The sync operation can be slightly complicated but make sense to me. More about to sync or not to sync, please refer to this link here.
