usermod equivalent for Alpine Linux












0















I'm building a Docker container, and I need to add my user to a group. usermod is not available in Alpine Linux by default. Apparently, you can add shadow from apk to install usermod, but I would prefer to not install additional packages.



Is there an alternative way to add a user to a group, or an equivalent tool to usermod available in Alpine?

  • Have you seen this? Basically adding environment variables for UID and GID when initializing.

    Why not simply modify the /etc/group file directly?

  • @davidgo Some people don’t know you can just edit it like that but it’s a good solution. Would need to be scriptable via sed or something like that.
