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.
