|
|
|
|
Last reviewed: 2026-07-03

|
|
|
Status: **in-cluster runner on railiance01** (ADR-004). Supersedes interim coulombcore
|
|
host runner.
|
|
|
|
## Purpose
|
|
|
|
Forge-owned Actions runner for `https://forgejo.coulomb.social` so `coulomb`
|
|
organization repos build and publish without workstation or legacy-host Docker.
|
|
Label contract aligns with `docs/gitea-actions-runner-substrate.md` and
|
|
`docs/ci-runner-actions-gitops-ownership.md`.
|
|
|
|

## Operator Commands
|
|
|
|
```bash
|
|
# S5 deploy (railiance-apps)
|
|
cd ~/railiance-apps
|
|
make forgejo-runner-registration-deploy # after SOPS encrypt
|
|
make forgejo-runner-deploy
|
|
make forgejo-runner-status
|
|
|
|
# Endpoint smoke
|
|
make forgejo-smoke
|
|
|
|
# Generate registration token (in cluster; do not log token)
|
|
KUBECONFIG=~/.kube/config-hosteurope kubectl exec -n forgejo deploy/forgejo-gitea -- \
|
|
forgejo actions generate-runner-token --scope coulomb
|
|
```
|
|
|
|
## Secret Boundaries
|
|
|
|
- `forgejo-runner-registration` Kubernetes Secret — registration token only.
|
|
- Repo/org registry credentials — Forgejo Actions secrets, not in Git.
|
|
- No kubeconfig or OpenBao tokens on the runner pod by default.
|
|
|
|
## Retired: Interim coulombcore Host Runner
|
|
|
|
`railiance-coulombcore-build-01` on coulombcore was a scheduling proof only.
|
|
Disable after in-cluster runner is healthy:
|
|
|
|
```bash
|
|
ssh coulombcore 'sudo systemctl disable --now forgejo-runner'
|
|
```
|
|
|
|
## Evidence
|
|
|
|
- Host probe (2026-07-03): `coulomb/forgejo-actions-probe` workflow `success`.
|
|
- In-cluster: verify with `make forgejo-runner-status` and a container `runs-on: ubuntu-latest` job.
