Before we can start using RESTRouter in k8s, we need to start building images for it. We need to add a Jenkins job for the [RESTBase source gerrit repository](https://gerrit.wikimedia.org/r/#/admin/projects/mediawiki/services/restbase) that builds said images on either a branch push or a tag push. This can be done by adding the repository to the [Zuul job configuration](https://github.com/wikimedia/integration-config/blob/ec54a561823d45715dcdda66f5eb65fe82f2e029/zuul/layout.yaml#L1359):
```lang=yaml
- name: mediawiki/services/restbase
<trigger>:
- trigger-service-pipeline-test-and-publish
```
Here, `<trigger>` can either be `post` (for branch push) or `publish` (for a tag push).
NOTE: Before we enable the job in CI, we have to have [the Blubbler configuration merged](https://github.com/wikimedia/restbase/pull/1141)
