Docker Help

Most of the commands need to be known are inside containers.sh

Remove having to perform sudo for every docker command

$ sudo groupadd docker (Does not matter if the group is already added)

$ sudo gpasswd -a $USER docker (Add yourself to the docker group)

$ sudo service docker restart (Restart service)

IMPORTANT: Remember to log out and back in for these things to be in effect.

Where program is e.g bash/zsh/cqlsh.
