Installed a new debian server, installed docker, but then now i have a problem with permissions on passed directories.
On the previous server, the uid/gids inside the docker container match the uid/gid on the real server.
Root is 0, www-data is 33, and so on.
On this new server, instead, files owned by root (0) in the container are translated to 1000 on the server, www-data (33) is 100032, and so on (+1000 appended to the uid)
Is this normal or did I misconfigure something? On the previous server I was running everything as root (the interactive user was root), and i would like to avoid that
Niche use case, but you can also use
newgrpto run commands with a recently-added group to your user, without having to logout/login yet.
