Got it

To simplify, this condition should be an or statement that checks the presence of Values.server.env or whether Values.server.args.certificateAuthority == fileca. This would avoid the redundant PASSWORD env variable definition

I don't think the or condition between Values.server.env and Values.server.args.certificateAuthority == fileca would work because there might be a case where there are env variables specified as key-value pairs and the certificateAuthority == "<something not fileca>" at which point it would still try to populate the PASSWORD as a secret ref that is NOT optional and the pod might fail / retry due to lack of missing secret.

that is still fine. having the proposed conditional would still suffice. this conditional would remain in order to capture when it was defined, otherwise only the key/values would be captured. The contents within this conditional block can be removed as its no longer needed

secretKeyRef:
name: {{ .Values.server.secret }}

Is there an expected naming suggestion? I used this to maintain the existing convention between TSA and Fulcio helm chart. How about cloud_credential_config?
