From the app's own repository: github.com/woodpecker-ci/woodpecker/blob/aca84ce/docker-compose.example.yaml.
Compose file from the app repository.
Install
- Docker with the Compose plugin (github.com/woodpecker-ci/woodpecker/blob/aca84ce/docker-compose.example.yaml)
A host with Docker and the Docker Compose plugin. This entry runs from a compose file.
- Save the compose file as compose.yaml (github.com/woodpecker-ci/woodpecker/blob/aca84ce/docker-compose.example.yaml)
Use the compose file shown above.
- Set the values the compose file needs (github.com/woodpecker-ci/woodpecker/blob/aca84ce/docker-compose.example.yaml)
These variables have no default in the compose file: WOODPECKER_AGENT_SECRET, WOODPECKER_GITHUB_CLIENT, WOODPECKER_GITHUB_SECRET, WOODPECKER_HOST. Compose reads them from the shell or from a .env file next to the compose file.
- Start it (github.com/woodpecker-ci/woodpecker/blob/aca84ce/docker-compose.example.yaml)
docker compose up -d - Open the app (github.com/woodpecker-ci/woodpecker/blob/aca84ce/docker-compose.example.yaml)
Open http://localhost:8000. The compose file publishes host port 8000 for the woodpecker-server service.
Compose file check: config_ok on 2026-10-22.
Gotchas and maintenance
Gotchas
- The compose file publishes host ports. Host ports: 8000 (woodpecker-server). A port without a host address listens on all host network interfaces. (github.com/woodpecker-ci/woodpecker/blob/aca84ce/docker-compose.example.yaml, checked 2026-10-22)
- The compose file mounts host folders. Host paths mounted into containers: /var/lib/woodpecker at /var/lib/woodpecker/ (woodpecker-server). (github.com/woodpecker-ci/woodpecker/blob/aca84ce/docker-compose.example.yaml, checked 2026-10-22)
- Some services get elevated host access. woodpecker-agent mounts the Docker socket, which gives it control of Docker on the host. (github.com/woodpecker-ci/woodpecker/blob/aca84ce/docker-compose.example.yaml, checked 2026-10-22)
