This question might be better for the GLASS mailing list (https://gemtalksystems.com/techsupport/community-and-mailing-lists/), but I���m happy to respond here.

I wrote about GemStone in a Docker container in 2018 (see https://programminggems.wordpress.com/2018/09/01/gemstone-in-a-docker-container/ and https://github.com/jgfoster/DockerForGemStone) and David Schaffer has a nice follow-up that he has keep up-to-date at https://github.com/cdavidshaffer/gemstone-docker. There is also one from Juli��n Maestri at https://hub.docker.com/r/basmalltalk/gemstone-s.
