<!-- cspell:ignore buildah Containerfile roundcube -->
|
|
|

I run Woodpecker CI with podman backend instead of docker and just figured out how to build images with buildah. Since I couldn't find this anywhere documented, I thought I might as well just share it here.

It's actually pretty straight forward. Here's what my repository structure looks like:
|
|
|
|
```bash
|
|
.
|
|
├── roundcube
|
|
│ ├── Containerfile
|
|
│ ├── docker-entrypoint.sh
|
|
│ └── php.ini
|
|
└── .woodpecker
|
|
└── .build_roundcube.yml
|
|
```
|
|
|
|
As you can see I'm building a roundcube mail image.
|
|
|
|
This is the `.woodpecker/.build_roundcube.yaml`
|
|
|
|
```yaml
|
|
when:
|
|
event: [cron, manual]
|
|
cron: build_roundcube
|
|
|
|
steps:
|
|
build-image:
|
|
image: quay.io/buildah/stable:latest
|
|
pull: true
|
|
privileged: true
|
|
commands:
|
|
- echo $REGISTRY_LOGIN_TOKEN | buildah login -u <username> --password-stdin registry.gitlab.com
|
|
- cd roundcube
|
|
- buildah build --tag registry.gitlab.com/<namespace>/<repository_name>/roundcube:latest .
|
|
- buildah push registry.gitlab.com/<namespace>/<repository_name>/roundcube:latest
|
|
|
|
secrets: [registry_login_token]
|
|
```
|
|
|
|
As you can see, I'm using this workflow over at gitlab.com. It should work with GitHub as well, with adjusting the registry login.
|
|
|
|
You may have to adjust the `when:` to your needs. Furthermore, you must check the `trusted` checkbox in project settings. Therefore, be sure to run trusted code only in this setup.
|
|
|
|
This seems to work fine so far. I wonder if anybody else made this work a different way.
|
|
|
|
EDIT: Removed the additional step that would run buildah in a podman container. I didn't know it could be that easy to be honest.
