The Docker container for the core GAP system is available at DockerHub here: https://hub.docker.com/r/jamesdbmitchell/gap-docker-minimal-arm
This GAP Docker container provides only the core GAP system and several packages
which are needed by GAP (PackageManager, GAPDoc, PrimGrp, SmallGrp, TransGrp).
It may be used, for example, in automated tests of different configurations of
GAP packages by installing them in the pkg subdirectory of
/home/gap/inst/gap-4.X.Y/.
If you install Docker, you may run GAP in this container interactively.
$ docker run --rm -i -t jamesdbmitchell/gap-docker-minimal-arm:version-4.12.0
