ROOT CAUSE: All 3 runner labels pointed to code.forgejo.org/forgejo/runner:6
(bare Alpine). When Forgejo runs a workflow, it creates a container FROM the
label image — this container had no Node.js, no docker CLI, no Go/Rust,
no root access, and no apt-get. Every CI job failed.
FIX: Change runner labels to official Debian-based language images:
golang → docker://golang:1.26-bookworm (Go + apt-get + root)
node → docker://node:22-bookworm (Node.js + npm + apt-get + root)
rust → docker://rust:1-bookworm (Rust + cargo + apt-get + root)
The runner daemon pod still uses forgejo/runner:6 — only the label image
(what workflow steps execute in) changes.
Unified CI pattern for ALL repos:
1. Install Node.js first if not present (needed for actions/checkout@v4)
2. Install docker.io via apt-get (needed for docker build/push)
3. Use actions/checkout@v4 normally
4. Build/push with docker
IMPORTANT: Runners must re-register after merge. Delete PVCs or
/data/.runner files to trigger re-registration with new labels.
- 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.
