gitea/runner can only bind-mount a UNIX-socket docker host into job
containers — the old tcp://localhost:2376 + TLS daemon address cannot be
mounted, so build jobs still had no docker API. Share dind's
/var/run/docker.sock with the runner via a /var/run emptyDir and drop the
DOCKER_HOST/TLS env; the runner auto-finds the socket and the bind path
resolves inside dind where the socket lives.
gitea/runner 1.x no longer auto-mounts the docker daemon into job
containers (act_runner 0.2.x did), so 'docker build' in the build jobs
failed with 'cannot connect to /var/run/docker.sock'. container.docker_host
"" restores find-and-mount.
Gitea 1.26 never marked finished jobs complete with the deprecated
act_runner 0.2.11: the runner ran the job, logged 'Job succeeded' and freed
its slot, but Gitea kept the job 'Running' forever, so dependent jobs
(build -> deploy) were never dispatched. gitea/runner is the successor
project; config, env vars and the .runner registration file are unchanged.
Add an act_runner config.yaml (ConfigMap, CONFIG_FILE env): capacity 4 so the
typecheck matrix + image builds run in parallel instead of one-at-a-time, and
cache.enabled: false (we removed the setup-node cache; the cache server isn't
reachable from the DinD job containers anyway).
Self-registering act_runner on node1 with a privileged docker:dind sidecar so
workflow jobs can build + push app images (k3s has containerd only, no Docker
daemon). Labels ubuntu-latest + docker; state persisted on a Longhorn PVC. The
registration token is applied out-of-band as the gitea-runner-token Secret
(not in git). Verified: runner declared successfully, dind API up.
