This template repo builds a container from its Dockerfiles and registers them in GHCR
It registers multiarch containers and can do staged builds. Staged builds are for when you want multiple image tags registered at a single path. This allows you to maintain one source repo for many purposes. Sometimes only the base images can be compiled multiarch because the higher level images have unsupported dependencies.
The docker-compose.yaml file is an example... Each service can be an
additional tag off the main registry path.
docker-compose.yaml references a $USER variable that you should set in a
.env file:
$ cat .env
USER=ahayden
