There was a problem hiding this comment.
I can't find it right now but there has been a previous discussion about this - will look it up and link here later (on mobile right now)
I definitely get the desire to get the host UID/GID, particularly for bind mounts permissions, but I also am nervous about introducing something explicitly non-portable (and not even supported by all our platforms)

Example request for such feature: docker/compose#4081 (comment) |

Let's close this one as lack of portability is challenging here |

A very common issue using compose is to bind mount local files into container, and get into permission issues. Until docker engine provides some uid+gid translation on bind mounts (maybe using bindfs?) the only option is to run container with same user as the owner of the bind-mounted file
This introduce support for
UIDandGIDvariables on systems this makes sense (i.e. everything but Windows) so one can setuser: ${UID}:${GID}in a compose file.
