Image · CI/CD & registry · standard · v8.3.1
Concourse CI, built from the release tag with its web UI compiled and embedded in the one Go binary, the containerd, grpc and otel modules floated to their fixed releases. The web node (ATC and TSA) runs nonroot on a read-only rootfs against an external PostgreSQL; the worker runs privileged on Wolfi's containerd and runc with the CNI plugins built from source, and bundles the registry-image and time resource types built from their tags. The git resource type is its own image, concourse-git-resource.

Verify the supply chain
This image is cosign-signed and carries an SPDX SBOM and a SLSA build-provenance attestation on the same digest. Check all three yourself:
# 1. signature — built and signed by QuenchWorks CI
cosign verify ghcr.io/quenchworks/images/concourse:8.3.1 \
--certificate-identity-regexp 'https://github.com/quenchworks/.+' \

# 2. SLSA build provenance — which workflow built it, from what
cosign verify-attestation --type https://slsa.dev/provenance/v1 ghcr.io/quenchworks/images/concourse:8.3.1 \

Transparency
Every image carries its SBOM and provenance as attestations on the same digest, publicly verifiable with the commands above (they check the package and the Sigstore transparency log, Rekor).
