Operator decision on PR #81: no CI job may reach a privileged daemon. The act runner is untouched. - platform/buildkit (+ clusters/base/buildkit.yaml): moby/buildkit v0.34.1-rootless pinned by digest, uid 1000, not privileged; caps drop ALL + SETUID/SETGID, seccomp/AppArmor Unconfined, read-only rootfs (each measured under podman). cert-manager CA + server/client certs, ClusterIP :1234, default-deny with ingress only from the act-runner pod (DinD masquerades jobs to it). No Kyverno exception: every applied policy matches app-namespace=true only. - Each Containerfile names its shipped stage and ends in a `verify` stage holding every former `docker run` assertion (uid 65532, RUN --network=none, writable-path inventory standing in for the read-only rootfs). The old `&& echo` checks that could never fail are real assertions now. - images.sh drives buildkitd with a pinned buildx (sha256-checked) via bake; PRs build verify targets with agent-runner FROM the in-run toolbox (target: context); main verifies, then pushes. Fails loudly when the builder secrets are absent or buildkitd is unreachable. - infra/gitea/buildkit-client-secret.sh copies the client cert into Actions secrets.

# infra/devcontainer/build-image.sh — build the pinned dev `toolbox` image and prove it works.

# ONE BUILD DEFINITION, TWO CALLERS. `dev.sh build` calls this for local development. The CI
|
|
# image pipeline (.gitea/workflows/images.yaml -> .gitea/workflows/scripts/images.sh) builds the
|
|
# SAME Containerfile on rootless BuildKit (platform/buildkit/) — no container engine exists in a
|
|
# CI job — taking its build args from `--print-build-args`, and PUBLISHES the result as
|
|
# gitea.home.keithjackson.dev/home-network/toolbox. The Containerfile (including its `verify`
|
|
# test stage) and the arg list here are the one recipe both use.
|
|
#
|
|
# THIS SCRIPT NEVER PUSHES. Publishing is CI's job (images.yaml, on push to main), not a
|
|
# workstation's: an image that exists only because someone ran `podman push` from a laptop has
|
|
# no build log, no recorded inputs and no verification anyone else can read.
|
|
#
|
|
# VERSIONS ARE NOT DEFINED HERE. infra/devcontainer/versions.env is the single source of truth.
