Argo CD EKS compatibility checks

Argo CD is a Platform addon dependency to validate before and after Amazon EKS control-plane upgrades. GitOps controllers surface deprecated APIs and sync failures during upgrades.

Why this add-on matters

  • GitOps controllers surface deprecated APIs and sync failures during upgrades.
  • Add-on type: Platform addon.
  • Primary source: Argo CD releases.

Preflight commands

  • argocd app list
  • kubectl -n argocd get pods

Upgrade validation

  • Confirm Argo CD is installed and owned by the expected delivery mechanism.
  • Review version compatibility and release notes before changing the EKS control plane.
  • Run workload smoke tests that exercise this add-on after each control-plane hop.
  • Capture output in the change packet with any exceptions or follow-up work.
