# A GitHub Actions workflow to build a docker image for an app.
#
# One-time setup to use this workflow:
# 1. Move this file into ./.github/workflows
# 2. Change APP_NAME variable below to the name of the app.
#
# The image will be built on each push to or pull request on main.
# It will be pushed to the current GitHub repo's Packages.
