helm install --name testapp ./testapp
Error: release testapp failed: ReplicationController "registry-creds-via-helm" is invalid: spec.template.spec.containers[0].env[0].valueFrom.secretKeyRef.name: Invalid value: "": a DNS-1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')

Can anyone point out what is the problem with my below yaml?
