# Re-points the existing LAN dev self-hosted runner from GitHub Actions to
|
|
# Forgejo Actions. Run on the SAME machine that already runs the GitHub
|
|
# runner (see DEPLOY-DEV.md) — this replaces that runner, it doesn't add a
|
|
# second one. Sudo-free, systemd --user, same pattern as the app service.
|
|
#
|
|
# This is THE runner (docs/runbooks/implementation-handoff.md Track B step 5
|
|
# — canonical placement is the desktop, not a Swarm-hosted container), so it
|
|
# registers with BOTH labels the workflows need, where one runner used to be
|
|
# two: general CI/build/deploy.yml jobs (`docker`, containerized via this
|
|
# machine's own already-installed Docker — no Docker-in-Docker sidecar needed,
|
|
# unlike the Swarm-hosted design this replaces, since a real host with a real
|
|
# Docker install needs no such indirection) and the LAN-deploy job
|
|
# (`thermograph-lan`, bare/host-native — it writes to ~/thermograph-dev and
|
|
# restarts a systemd --user service, which only works running directly on the
|
|
# host, not inside a container).

Done. The runner now serves Forgejo, not GitHub — one runner, both labels

($LABELS), replacing what used to be a separate Swarm-hosted runner for

general CI plus this machine's own GitHub runner for LAN deploys.

The old github-actions-runner unit was stopped and disabled but not deleted —

remove ~/actions-runner by hand once you've confirmed Forgejo deploys work.
