feat: Add support for existingSecret for htpasswd authentication #180
Conversation
Add support for referencing an existing Kubernetes secret for htpasswd authentication, avoiding plain text passwords in `values.yaml`. - Add `secrets.existingSecretHtpasswd` to reference an existing secret - Add `secrets.existingSecretHtpasswdKey` to specify the key name (defaults to "htpasswd") - Update templates to support both generated and existing secrets - Add README documentation ```yaml secrets: existingSecretHtpasswd: "my-htpasswd-secret" existingSecretHtpasswdKey: "htpasswd" # Optional ``` Create the secret: ```bash kubectl create secret generic my-htpasswd-secret \ --from-file=htpasswd=/path/to/htpasswd ``` If both `secrets.htpasswd` and `secrets.existingSecretHtpasswd` are set, the existing secret takes precedence.

Pull request overview
This PR adds support for referencing an existing Kubernetes secret for htpasswd authentication in the Verdaccio Helm chart, providing a more secure alternative to storing plain text credentials in values.yaml.
Key Changes:
- Added
secrets.existingSecretHtpasswdandsecrets.existingSecretHtpasswdKeyconfiguration options to reference external secrets - Updated deployment and statefulset templates to conditionally use either generated or existing secrets
- Modified secret generation logic to prevent conflicts when using existing secrets

The checksum annotation for existingSecretHtpasswd only concatenates the secret name and key, which won't detect changes to the actual secret content. This means pods won't automatically restart when the external secret is updated. Consider documenting that users need to manually trigger pod restarts when updating the external secret, or remove this checksum annotation entirely since Kubernetes doesn't automatically track changes to external secrets.

The inline conditional for subPath makes the template harder to read. Consider moving this logic to a helper template or using a clearer multi-line if-else structure for better maintainability.
