Add Helm Code Block (For Reference) to Sync Wave Documentation Page

[josephaw1022]

Summary

⚠️ Small Docs Update

In the sync waves page https://argo-cd.readthedocs.io/en/stable/user-guide/sync-waves/

I think a short code block that shows how the ARGOCD_SYNC_WAVE_DELAY in the helm chart can be configured

like this

controller:
  env:
    - name: ARGOCD_SYNC_WAVE_DELAY
      value: "30"

Motivation

• my first question was is the default value 2 or 2s

  • was able to figure it out by looking at the code, here but I think just having it in the page would make it easier

• wasn't sure how to configure this in the helm chart initially

Proposal

add a code block below the following note in the docs

Note: there is a delay between each sync wave to give other controllers a chance to react to the applied spec change. This prevents Argo CD from assessing resource health too quickly (against a stale object), and firing hooks prematurely. The default delay between each sync wave is 2 seconds. This can be adjusted by setting the ARGOCD_SYNC_WAVE_DELAY environment variable in the argocd-application-controller deployment.
