You add a user to group docker so that you can run docker commands without having to be root or a sudoer.
On an Ubuntu 16.04 server which authenticates against AD using PBIS, I added users to group docker, but wasn’t getting recognized at all and had to use sudo, which defeats the purpose.
All I did was the following:
- Edit /etc/group
- go to the bottom of the file where you will find the docker group
- change the name of the AD group from lower case to upper case characters and save, e.g.:
docker:x:999:hobba\socrat to docker:x:999:HOBBA\socrat
