Caching forward proxy for HTTP and HTTPS (CONNECT). Pods reach the outside through it, and it caches repeat fetches in memory. The default config allows RFC 1918 and CGN sources and refuses CONNECT to anything but port 443. The chart supplies the config.

Version

0.0.4 · latest0.0.30.0.2

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.
