Collapse the certReloader (mtime tracking, serialized refresh, retry backoff,
rate-limited logging, last-good-certificate fallback) into a GetCertificate
callback that simply re-reads the key pair from disk on every handshake. The
signature is unchanged, so main.go is untouched.
The extra machinery guarded scenarios this deployment cannot produce:
- Torn reads are unreachable: the cert/key files come from a plain Secret
volume with no subPath, and Kubernetes' atomic writer swaps the whole ..data
directory via a single symlink flip, so a reader always sees a complete old
or complete new generation of both files.
- The per-handshake LoadX509KeyPair cost is negligible next to the asymmetric
crypto the handshake already performs, so no cache is needed.
- The webhook configures no mTLS, so GetCertificate not refreshing client CA
pools does not apply.
If the mounted files genuinely become unreadable (an operator error, not a
renewal) the handshake now fails loudly instead of silently serving a stale
certificate. The core regression test is retained and remains non-vacuous: it
fails against a static tls.Config.Certificates and passes with the reloading
callback.
