# CI support stuff

## Docker image

GitLab CI jobs run in a Docker image, defined here. To update that image
(perhaps to install some more packages):

1. Edit `.gitlab-ci/Dockerfile` with the changes you want
1. Run `.gitlab-ci/run-docker.sh build --base=debian-stable --base-version=1` to
   build the new image (bump the version from the latest listed for that `base`
   on https://gitlab.gnome.org/GNOME/gnome-software/container_registry)
1. Run `.gitlab-ci/run-docker.sh push  --base=debian-stable --base-version=1` to
   upload the new image to the GNOME GitLab Docker registry
    * If this is the first time you're doing this, you'll need to log into the
      registry
    * If you use 2-factor authentication on your GNOME GitLab account, you'll
      need to [create a personal access token][pat] and use that rather than
      your normal password
1. Edit `.gitlab-ci.yml` (in the root of this repository) to use your new
   image
