Hello Guix, On current master, ‘guix system docker-image’ produces an image without an entry point, so one has to carefully follow the “GUIX_NEW_SYSTEM hack” described in the manual. Furthermore, due to other issues, the resulting image doesn’t properly boot because it tries to mount file systems that it cannot mount, such as /dev/shm and /dev/pts. These patches fix both issues, such that one can just do ‘docker create’ and ‘docker start’ to get Guix System up and running in the container. I think that’s a nice improvement. :-) We discussed this Friday on IRC and people said that it’s quite unusual to provide a “full OS” (with PID 1) as a Docker image; instead, people would rather do one image per (micro)service. But anyway, that’s the purpose of ‘guix system docker-image’, and I can imagine it has use cases too. For example, it’s a simple way to get Guix set up in a container, for people who want to perform Guix builds in a container. Thoughts? Ludo’.
