Summary
This PR prepares the #688 Forgejo runner hardening apply by removing the direct Docker socket mount from the runner container and routing Docker API calls through a constrained
docker-socket-proxysidecar.It also updates the runner hardening audit so the critical
raw_docker_socket_mountedfinding clears only when the runner usesDOCKER_HOST=tcp://docker-socket-proxy:2375and the proxy explicitly disables dangerous Docker API categories.Refs #688.
#688 live status
Already applied and verified on RS2000 before this PR:
home-platform-postgres-1:postgres:16.14-alpine@sha256:16bc17..., healthy.home-platform-kan-postgres-1:postgres:16.14-alpine@sha256:16bc17..., healthy.task_run,task_run_event,task_checkpoint, and procedure registry tables exist in live main Postgres DB with append-only triggers.This PR is the repo-side safety-net for the remaining runner item. Do not close #688 on merge alone; close it only after the live runner cutover and CI smoke pass.
Canary Context Pack
Product story
The normal Forgejo Docker runner should keep PR CI working while reducing the direct host-compromise surface from the raw Docker socket mount.
What changed
docker-socket-proxytoinfra/forgejo-runner/docker-compose.ymlwith a pinned digest./var/run/docker.sockfrom the runner service.DOCKER_HOST=tcp://docker-socket-proxy:2375.Why it changed
#688 is the operator-approved runtime batch for pending applies. The runner part needed a repo-reviewed safety-net before touching
/opt/forgejo-runnerlive state.Files touched

runbooks/forgejo-actions-runner.md: live runner operation and rollback path.docs/ci/runner-contract.md: runner boundary and deploy separation.Runtime evidence
No live runner mutation in this PR. Live evidence before this PR showed
forgejo-runnermounted/var/run/docker.sockdirectly. After merge, apply should copy the versioned compose file to/opt/forgejo-runner/docker-compose.yml, rundocker compose up -d, and smoke a normal PR check.Known constraints
A Docker socket proxy is not full isolation. It reduces direct socket exposure but the remaining
docker:hostlabel, persistent/data, and runner-local Infisical token still need follow-up hardening.Explicit out-of-scope
docker:hostlabel yet.Requested decision
Approve this as the repo-side safety-net for #688 runner cutover.
