name: Docker Image For Main Builds
# we want to be able to sort by tag name to find the newest and trace back to source control
# on every commit to main:
#   frontend:main-20230223164322-b8becd1-45
#   frontend:main-latest
# we settled on:
#   main-2023-02-24_16-16-40
# because the labels on the docker image itself have the git sha and everything else :)
# on every tag:
#   frontend:latest
#
# Example docker image labels:
#     "Labels": {
#       "description": "Software development platform for building, running, and monitoring executable diagrams",
#       "org.opencontainers.image.created": "2023-02-24T16:43:00.844Z",
#       "org.opencontainers.image.description": "",
#       "org.opencontainers.image.licenses": "LGPL-2.1",
#       "org.opencontainers.image.revision": "54064a050fbf9f366648f0f2e2c60ce244fcc421",
