The CI job wikimedia-portals-build should be migrated to use Docker container. As of July 2019 it runs on Jenkins instances based on Debian Jessie which are provisioned with puppet. That infrastructure is deprecated and has to be dismissed in favor of using Docker containers.
The job wikimedia-portals-build runs every Monday and roughly:
- git clone wikimedia/portals.git
- run npm install && npm test && npm run-script build-all-portals, that results in assets intended to power https://www.wikipedia.org/
- Craft a commit adding the content of ./prod and send that to Gerrit for review against wikimedia/portals/deploy.git
- A human +2 the change, once merged operations/mediawiki-config.git has the submodule bumped and the portal assets are deployed using a wrapper around scap, similar to how mediawiki-config changes are deployed.
