Connaisseur, the Kubernetes admission controller that verifies container image signatures (Cosign/Sigstore, Notary v1 and v2) against trust roots before a pod is admitted, with per-image policy rules. Serves HTTPS on 5000 with /mutate, /health and /metrics; config and certificates are mounted under /app.

Version

The latest line lives at the base page; older lines have their own page so you can pin and verify exactly that version. Only the most recent releases are listed — an older chart pins an older image digest.

Transparency

The chart publishes its attestations on GitHub and the image it deploys carries its own on the same digest, publicly verifiable with the commands above. Both log to the Sigstore transparency log (Rekor), which cosign verify checks for you.
