Docker Compose .env

USER_ID: Id of local user executing docker instance
GROUP_ID: Group id from local user executing docker instance
ALMA_DIR: Path that has all the directories that will be mounted as /alma in the container, for instance in my examples is '/external/docker/'
- Inside this directory there's a set of directories for each OS, each will be mounted as /alma for the different images/containers. For instance '/external/docker/centos7' will be mounted as /alma in centos7 containers
REPO_DIR: Path to the Git Repository. In my case inside this path (/external/Repos) I have 'almasw' and 'worktrees', which allow to have several worktrees for building without affecting other parts of the system
CONTAINER_OS: Here I define the default OS to be used. This can be overridden on command line if other OS is going to be used, but the default one should be defined here

An example of the .env file:

USER_ID=1000
GROUP_ID=1000
ALMA_DIR=/external/docker/alma
HOME_DIR=/external/docker/home
REPO_DIR=/external/Repos
CONTAINER_OS=centos7
