To start a docker container with the current user I can call docker run with the --user parameter like
docker run --user $(id -u):$(id -g) myimage
However that leaves the user inside the container without a name which inhibits the execution of some programs. For example it is not possible to mount a directory via fuse as a user without a name.
So what is the preferred approach to specify the UID and the username for a docker run command?
The only workaround I have found so far is to bind-mount /etc/password into the container:
docker run -v /etc/passwd:/etc/passwd:ro --user $(id -u):$(id -g) myimage
but that looks rather ugly to me. Isn't there a better way to do this?
