Run the container as a specific user/group ?

[qwrty-ftw]

Hello,

by default container is created and run with uid:gid = 1000:1000 which are shared with the host.
So finally container on the host run with the host user which have the same uid:gid = 1000:1000

I tried to add user: 1001:1001 in my docker-compose file, but I got permission issue because my host user 1001:1001 doesn't have the good right inside the container.

How can I do to run container with a specific user uid:gid and avoid permission issue ?
I guess I have to edit the dockerfile ?

Thank you
