Pods not showing in ArgoCD UI

Description

Occasionally, the ArgoCD UI does not show pods, but only displays applications and corresponding deployments. See the following image for details:

When selecting on any of the deployments, the following error is displayed: Unable to load data: EOF.

Solution

You can fix this issue by deleting all Redis replicas from ArgoCD namespace and waiting for it to come back up again.

kubectl -n argocd delete pod argocd-redis-ha-server-0 argocd-redis-ha-server-1 argocd-redis-ha-server-2

# Wait for all 3 pods to come back up
kubectl -n argocd get pods | grep argocd-redis-ha-server
