All CI workflows across all repos were broken. Three root causes:
1. Runner labels pointed to bare Alpine image (forgejo/runner:6) which has
no Node.js, no docker, no Go/Rust, no root, no apt-get. Every workflow
step failed immediately.
Fix: Change labels to official Debian language images:
golang → docker://golang:1.26-bookworm
node → docker://node:22-bookworm
rust → docker://rust:1-bookworm
2. Docker socket not shared between dind sidecar and runner container.
dind creates /run/docker.sock in its own filesystem. Runner container
has a separate filesystem and can't see it. Workflow containers that
run 'docker build' get 'Cannot connect to Docker daemon'.
Fix: Share /run between dind and runner via emptyDir volume.
Add docker_host: automount to runner config so the socket is
mounted into workflow containers automatically.
Note: /var/run is a symlink to /run in Alpine — must mount at /run.
3. Init container skipped re-registration if .runner file existed on PVC.
Changing labels in values.yaml had no effect until PVC was manually
deleted — not GitOps-friendly.
Fix: Always rm .runner and re-register on pod start. Labels stay
in sync with values.yaml automatically.
Also removes custom Dockerfiles and build-runner-images workflow — no longer
needed since official images provide the language tools directly.
- All runners now based on code.forgejo.org/forgejo/runner:6 (has runner binary)
- Dockerfile adds Node.js + specialized tools (Go, Rust, docker)
- CI workflow will build custom images and push to registry
- Image Updater will auto-detect and update values.yaml
- ArgoCD will sync new custom images when available
- Dockerfile.node extends node:22-bookworm with docker.io
- No need for install step in every workflow
- Values-node.yaml references custom image
- Build and push manually (no CI needed)
- Reverted to node:22-bookworm (no custom image)
- Removed Dockerfile.node (no CI to build it)
- Docker install step in riotpiao workflow is already the workaround
- Dockerfile.node extends node:22-bookworm + docker.io
- CI workflow builds and pushes to forgejo registry on changes
- values-node.yaml references custom image instead of stock node
- Removes need to install docker in every workflow using node runner
- Add gc-cronjob.yaml: daily prune of DinD Docker images/volumes/build-cache
and actcache across all forgejo-runner pods. Keeps :latest tagged images,
deletes non-latest older than 72h.
- Expand runner reg PVCs from 1Gi to 20Gi (all three runners) to prevent
action tool cache from filling disk.
- Rust runner gets explicit 20Gi persistence override.
- GC only renders from golang (default) values to avoid duplicate resources.
