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:
.env example
USER_ID=1000 GROUP_ID=1000 ALMA_DIR=/external/docker REPO_DIR=/external/Repos CONTAINER_OS=centos7
