Hi Folks, Hoping to get some clarification as to what I'm missing here... I ran the following command: sudo usermod -aG docker ${USER} Which resulted in the following entry in /etc/group docker:x:133:bulwynkl OK, all nice and as it should be. su - bulwynkl then id shows I am a member of group docker. but. when I close terminal and restart it OR when I log out and log back in again and run terminal, the group hasn't taken. running id shows no docker group membership. once again - if I run su - bulwynkl, then id, I DO get docker group... so... what am I missing - presumably something is holding onto the old session data even for a logout? N.B. rebooting solved the issue. but that isn't very satisfactory - fine on a home laptop - annoying, but fine - less so on a production machine... IIUC, openning a new terminal SHOULD re-read the .bashrc &etc config files... -- Dr Paul van den Bergen
