BuildKit, the concurrent container image build engine behind docker build, as the rootless variant: buildkitd runs under rootlesskit as uid 1001 on Wolfi runc and fuse-overlayfs, with buildctl in the same image. Built from source with its containerd, go-archive and otel modules floated.

Version

0.0.11 · latest0.0.100.0.9

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.
