I want to 'undo' adding myself to docker group

in flag
Olives8072

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.

You can reverse the sudo adduser $USER docker command with the following:

sudo deluser $USER docker

However I don't think this is necessary. I have no experience with Docker, but adding yourself to any group doesn't automatically make you root. It rather gives you the ability to elevate to root if needed - which you probably have anyway, if you are able to use sudo :)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
