## Docker compose with docker-in-docker
|
|
|
|
The `compose-forgejo-and-runner.yml` compose file runs a Forgejo
|
|
instance and registers a `Forgejo runner`. A docker server is also
|
|
launched within a container (using
|
|
[dind](https://hub.docker.com/_/docker/tags?name=dind)) and will be
|
|
used by the `Forgejo runner` to execute the workflows.
|
|
|
|
### Quick start
|
|
|
|
```sh
|
|
rm -fr /srv/runner-data /srv/forgejo-data
|
|
secret=$(openssl rand -hex 20)
|
|
sed -i -e "s/{SHARED_SECRET}/$secret/" compose-forgejo-and-runner.yml
|
|
docker compose -f compose-forgejo-and-runner.yml up -d
|
|
docker compose -f compose-forgejo-and-runner.yml -f compose-demo-workflow.yml up demo-workflow
|
|
firefox http://0.0.0.0:8080/root/test/actions/runs/1 # login root, password {ROOT_PASSWORD}
|
|
```
|
|
|
|
### Running
|
|
|
|
Create a shared secret with:
|
|
|
|
```sh
|
|
openssl rand -hex 20
|
|
```
|
|
|
|
Replace all occurences of {SHARED_SECRET} in
|
|
[compose-forgejo-and-runner.yml](compose-forgejo-and-runner.yml).
|
|
|
|
> **NOTE:** a token obtained from the Forgejo web interface cannot be used as a shared secret.
|
|
|
|
Replace {ROOT_PASSWORD} with a secure password in
|
|
[compose-forgejo-and-runner.yml](compose-forgejo-and-runner.yml).
|
|
|
|
```sh
|
|
docker-compose -f compose-forgejo-and-runner.yml up
|
|

|

|
|
### Manual testing
|
|
|
|
To login the Forgejo instance:
|
|
|
|
* URL: http://0.0.0.0:8080
|
|
* user: root
|
|
* password: {ROOT_PASSWORD}
|
|
|
|
`Forgejo Actions` is enabled by default when creating a repository.
|
|
|
|
## Tests workflow
|
|
|
|
The `compose-demo-workflow.yml` compose file runs a demo workflow to
|
|
verify the `Forgejo runner` can pick up a task from the Forgejo instance
|
|
and run it to completion.
|
|
|
|
A new repository is created in root/test with the following workflow
|
|
in `.forgejo/workflows/demo.yml`:
|
|
|
|
```yaml
|
|
on: [push]
|
|
jobs:
|
|
test:
|
|
runs-on: docker
|
|
steps:
|
|
- run: echo All Good
|
|
```
|
|
|
|
A wait loop expects the status of the check associated with the
|
|
commit in Forgejo to show "success" to assert the workflow was run.
|
|
|
|
### Running
|
|
|
|
```sh
|
|
$ docker-compose -f compose-forgejo-and-runner.yml -f compose-demo-workflow.yml up demo-workflow
|
|
...
|
|
demo-workflow_1 | To http://forgejo:3000/root/test
|
|
demo-workflow_1 | + 5ce134e...261cc79 main -> main (forced update)
|
|
demo-workflow_1 | branch 'main' set up to track 'http://root:admin1234@forgejo:3000/root/test/main'.
|
|
...
|
|
demo-workflow_1 | running
|
|
...
|
|
```
