 ## Pushing new images
 
 Once a commit is merged to main which updates the build-image Dockerfiles, a
 maintainer must push a tag matching the pattern `build-image/vX.Y.Z` to the

 Automation will trigger off of this tag being pushed, building and pushing the
 new build images to Docker Hub.
 
 A follow-up commit to use the newly pushed build images must be made.
