# Builds the image of @pdsjs/git-ci, the check runner, on a version tag,
# and publishes it as the `pds.js-git-ci` release of this repository:
# `docker pull knotless.dev/chadtmiller.com/pds.js/pds.js-git-ci:<version>`.
# It copies it to the pdsjs.dev PDS's own registry too. release-image.yml
# says how the image is built and published with no docker daemon.
