Forgejo Runner

WARNING: this is alpha release quality code and should not be considered secure enough to deploy in production.

A daemon that connects to a Forgejo instance and runs jobs for continous integration. The installation and usage instructions are part of the Forgejo documentation.

Reporting bugs

When filing a bug in the issue tracker, it is very helpful to propose a pull request in the end-to-end tests repository that adds a reproducer. It will fail the CI and unambiguously demonstrate that the problem exists. In most cases it is enough to add a workflow (see the echo example). For more complicated cases it is also possible to add a runner config file as well as shell scripts to setup and teardown the test case (see the service example).

Hacking

The Forgejo runner depends on a fork of ACT and is a dependency of the setup-forgejo action. See the full dependency graph for a global view.

Local debug

The repositories are checked out in the same directory:

Install dependencies

The dependencies are installed manually or with:

setup-forgejo/forgejo-dependencies.sh

Build the Forgejo runner with the local ACT

The Forgejo runner is rebuilt with the ACT directory by changing the runner/go.mod file to:

replace github.com/nektos/act => ../act

Running:

cd runner ; go mod tidy

Building:

cd runner ; rm -f forgejo-runner ; make forgejo-runner

Launch Forgejo and the runner

A Forgejo instance is launched with:

cd setup-forgejo
./forgejo.sh setup
firefox $(cat forgejo-url)

The user is root with password admin1234. The runner is registered with:

cd setup-forgejo
docker exec --user 1000 forgejo forgejo actions generate-runner-token > forgejo-runner-token
../runner/forgejo-runner register --no-interactive --instance "$(cat forgejo-url)" --name runner --token $(cat forgejo-runner-token) --labels docker:docker://node:20-bullseye,self-hosted:host://-self-hosted,lxc:lxc://debian:bullseye

And launched with:

cd setup-forgejo ; ../runner/forgejo-runner --config runner-config.yml daemon

Note that the runner-config.yml is required in that particular case to configure the network in bridge mode, otherwise the runner will create a network that cannot reach the forgejo instance.

Try a sample workflow

From the Forgejo web interface, create a repository and add the following to .forgejo/workflows/try.yaml. It will launch the job and the result can be observed from the actions tab.

on: [push]
jobs:
  ls:
    runs-on: docker
    steps:
      - uses: actions/checkout@v3
      - run: |
          ls ${{ github.workspace }}
