# Description. This Github action runs when there are new commits to dev-v3, prod-v3, or v3-release-*.
# The action logs into Docker with the Github action environment secrets `DOCKERHUB_USERNAME`
# and `DOCKERHUB_TOKEN`.
# The action pulls the repo and builds the abaco/core-v3 image and uses branch name as the
# docker tag. In instance of `v3-release-1.2.0`, sed will delete `v3-release-`, leaving `1.2.0`.
# If branch = prod-v3, tag becomes `staging` so staging is also built.
#
# NOVEMBER 16th:
