Redis HA Proxy


Manual intervention might be required to complete the upgrade.

High-availability (HA) Argo CD manifests now bundles Redis in HA Proxy in front of it. Following issue have been observed during the upgrade:

  • you might see intermittent login failures;
  • after upgrade is completed ha proxy might be unable to access redis server (see argo-cd#3547, DandyDeveloper/charts#26). As workaround "restart" argocd-redis-ha-haproxy Deployment and argocd-redis-ha-server StatefulSet.

Upgraded Kustomize Version

Note that bundled Kustomize has been upgraded to v3.6.1.

From here on you can follow the regular upgrade process.
