What are the steps to resolve an x509 certificate expired causing Redis to be unavailable in Automation Suite?
Root Cause: The Rancher Webhook certificate is expired. Hence Redis pods are out of sync/missing/down due to expired x509 certificate in log.
Resolution: The steps to renew Rancher Webhook certificate are as follows,
kubectl delete secret -n cattle-system cattle-webhook-tls
kubectl delete mutatingwebhookconfigurations.admissionregistration.k8s.io --ignore-not-found=true rancher.cattle.io
kubectl delete pod -n cattle-system -l app=rancher-webhook
