Rethink our image tagging strategy
From @joe-shaw on !1596 (comment 959921983)
I think this image tagging approach might need rethinking in the future as it gets increasingly awkward to maintain. Not sure of an ideal solution. Most projects seem to just build images with the commit SHA, but it would mean constantly updating the docker-json images and mean all images are constantly updated. Perhaps a model using actual image digests would work.
