# mount /etc/group and /etc/passwd read only
# set user from $USER
docker run -ti --rm -v $(pwd):/tmp/hx -w /tmp/hx -v /etc/group:/etc/group:ro -v /etc/passwd:/etc/passwd:ro —user=$USER debian:jessie

#With newer versions of docker volumes don't get mounted until after the user is assumed. However, if you use -u=$UID instead of --user=$USER it will work.
#If you want to match the group id too you can do -u=$UID:$(id -g $USER)
