I'm using Ubuntu 20.04.
I installed Docker from Snap Store. Then i started running the commands as recommended on the page, because i wanted to be able to run it as a normal user.These are the command that i run:
sudo addgroup --system docker
sudo adduser $USER docker
newgrp docker
sudo snap disable docker
sudo snap enable docker
And after completing running them all, i saw the warning on the same page:
Warning: if you add your user to the docker group, it will have similar power as the root user. For details on how this impacts security in your system, see https://docs.docker.com/engine/security/#docker-daemon-attack-surface
Since i am an inexperienced user, this warning got me a little scared.
My question is, how do i undo that? How do i revert everything back to the moment before i started installing Docker?
Thanks.
