How to update ArgoCD

Our configuration was set up with the help of the Argo-CD Autopilot. The Argo-CD Autopilot is a tool which offers an opinionated way of installing Argo-CD and managing GitOps repositories.

The autopilot bootstrap command will deploy an Argo CD manifest to a target K8s cluster. This Application will manage the Argo CD installation itself - so after running this command, you will have an Argo CD deployment that manages itself through GitOps.

• The ArgoCD version is determined through the components/talos-cluster/manifests/bootstrap/argo-cd/kustomization.yaml file.
• To Update the ArgoCD version, just update resources URL in the thekustomization.yaml file to point to the desired version of ArgoCD.

Initial config from the ArgoCD Autopilot and its downside

• The initial config from the ArgoCD Autopilot points to github.com/argoproj-labs/argocd-autopilot/manifests/base?ref=v0.4.18 references a config which is marked as stable.
• However, this means that we cannot determine the exact version of ArgoCD that is being deployed and hence cannot determine when to update ArgoCD ourselves.
• We found a way around this by changing the resources URL in the kustomization.yaml file to point to a specific version of ArgoCD (see https://github.com/sommerfeld-io/configs-homelab/blob/main/components/talos-cluster/manifests/bootstrap/argo-cd/kustomization.yaml).
