Runner Fleet - GitHub Actions Runner Manager

文档 (Docs): 中文 · Français · Deutsch · 한국어 · 日本語

HTTP management UI built with Golang Echo to view and manage multiple self-hosted GitHub Actions Runners on one machine. YAML-based config, no database required.

Linux only (linux/amd64, linux/arm64): runner liveness is read from /proc. The UI and its messages follow six languages; logs are fixed to English — see the User Guide.

Highlights

• Zero database: YAML-only config, no external deps; the config is your backup and is easy to version.
• Web one-stop: add, register, start/stop, edit and inspect runners in the UI — no SSH, no hand-run config.sh. Paste GitHub's ./config.sh --url … --token … and the form fills itself; name and directory conflicts surface while you type, with a suggested name.
• Container-first: Docker / docker-compose out of the box; DinD and host-socket for in-job Docker; optional container mode (one runner per container) with the Manager owning lifecycle and status.
• Config drift is repaired, not just reported: image, network, mount directory, in-job Docker backend and the agent token are all fixed at docker create time, so editing the config never reached an existing container. The Manager compares each container against the current config — a stopped runner is rebuilt on its next start, a running one is flagged with the exact difference and rebuilt when you say so.
• Hosted-CLI baseline + custom images: stock images align the CLI layer with GitHub-hosted ubuntu-24.04; extend with Android / Node and friends via examples/runner-images/ and per-runner container_image.
• Self-heals, and says why when it can't: registered-but-stopped runners start ~15s after boot and are re-checked every 5 minutes; in container mode a failed probe returns a structured diagnosis — error type, a check command and a fix command — instead of a bare "unknown".
• Observable: /ready and Prometheus /metrics for the deployment, the registration result per runner, and an optional PAT that keeps the UI in sync with what GitHub actually lists.

Quick start

mkdir -p config runners && cp config.yaml.example config/config.yaml
# Edit config/config.yaml: set runners.base_path to /app/runners
sudo chown -R 1001:1001 config runners

docker network create runner-net 2>/dev/null || true
docker compose up -d

Self-hosted runners should serve private repositories only — a pull request to a public repository can run code on this machine. See SECURITY.md.

Open http://localhost:8080. The default image tag is the stable release (e.g. v1.9.0). For more options (docker run, DinD, container mode, using main or other tags) see the User Guide. Probes, Prometheus metrics and logging: Operations — GET /health (liveness), GET /ready (readiness), GET /metrics, GET /version.

Two copy-and-go deployments live in examples/deploy/: standalone/ (single container, runner processes inside the Manager — docker run or Compose) and fleet/ (one container per runner, image and toolchain caches shared, build caches isolated).
