GitOps the Hard Way, with Argo CD

Ordering Within a Phase: Sync Waves

A phase can contain several resources. Suppose you have two PreSync jobs and one has to finish before the other starts. The phase alone does not order them, since they share the PreSync phase. In that case, you need sync waves.

Annotate resources with argocd.argoproj.io/sync-wave, an integer that defaults to 0. Within a phase, Argo CD applies lower waves first and waits for each wave to become healthy before starting the next.

# Wave 0: runs first
metadata:
  generateName: db-migrate-
  annotations:
    argocd.argoproj.io/hook: PreSync
    argocd.argoproj.io/sync-wave: "0"
