# Build the docker container images that we will use for our Linux builds. This will
# identify the last commit to the repository that updated the docker images, and try
# to download the image tagged with that sha. If it does not exist, we'll do a docker
# build and push the image up to GitHub Packages for the actual CI/CD runs. We tag
# with both the sha and "latest" so that the subsequent runs need not know the sha.
