# Forgejo Runner
|
|
|
|
**WARNING:** this is [alpha release quality](https://en.wikipedia.org/wiki/Software_release_life_cycle#Alpha) 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](https://forgejo.org/docs/next/admin/actions/) are part of the Forgejo documentation.
|
|
|
|
# Hacking
|
|
|
|
The Forgejo runner depends on [a fork of ACT](https://code.forgejo.org/forgejo/act) and is a dependency of the [setup-forgejo action](https://code.forgejo.org/actions/setup-forgejo). See [the full dependency graph](https://code.forgejo.org/actions/cascading-pr/#forgejo-dependencies) for a global view.
|
|
|
|
## Local debug
|
|
|
|
The repositories are checked out in the same directory:
|
|
|
|
- **runner**: [Forgejo runner](https://code.forgejo.org/forgejo/runner)
|
|
- **act**: [ACT](https://code.forgejo.org/forgejo/act)
|
|
- **setup-forgejo**: [setup-forgejo](https://code.forgejo.org/actions/setup-forgejo)
|
|
|
|
### Install dependencies
|
|
|
|
The dependencies are installed manually or with:
|
|
|
|
```shell
|
|
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:
|
|
|
|
```shell
|
|
cd runner ; rm -f forgejo-runner ; make forgejo-runner
|
|
```
|
|
|
|
### Launch Forgejo and the runner
|
|
|
|
A Forgejo instance is launched with:
|
|
|
|
```shell
|
|
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:16-bullseye,self-hosted:host://-self-hosted,lxc:lxc://debian:bullseye
|
|
```
|
|
|
|
And launched with:
|
|
|
|
```shell
|
|
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.
|
|
|
|
```yaml
|
|
on: [push]
|
|
jobs:
|
|
ls:
|
|
runs-on: docker
|
|
steps:
|
|
- uses: actions/checkout@v3
|
|
- run: |
|
|
ls ${{ github.workspace }}
|
|
```
