In this PR (also related to this one), an initContainer was added to the StatefulSet to copy mounted certificate secrets to an empty directory with a permission mode of 0400 (statefulset.yaml#L55-L84). However, the PR didn’t include details or references to the relevant Kubernetes bug that made these changes necessary for deploying the Helm charts. It seems that the file mode of mounted secrets wasn’t being set correctly. But in latest Kubernetes versions, at least 1.25+, this issue appears to have been resolved.

Additionally, the changes introduced in PR #62 require a restart of each CockroachDB node to rotate certificates. At my company, Devsisters, when we used the older chart (before PR #62), rotating secrets was much simpler because the Kubelet would automatically rotate the mounted secrets. All that was needed was sending a "SIGHUP" to the process. However, with the latest chart, rotating certificates provided by cert-manager now necessitates restarting each CockroachDB pod, as the secret is no longer directly mounted to the pod.

This is a cumbersome process that likely affects all users, the copy-certs initContainer should either be made optional or removed.
