HTTP reverse-proxy cache (web accelerator) that fronts an origin and serves its responses from memory, cutting backend load and tail latency. Caching policy is VCL, which varnishd compiles to native code at startup. The chart supplies the VCL and the backend.

Version

0.0.9 · latest0.0.80.0.7

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.
