Use Docker without sudo

To use docker without sudo, you need to be in the group docker.
Read the Docker docs: https://docs.docker.com/engine/install/linux-postinstall/#manage-docker-as-a-non-root-user

Here's what to do:

1. Check if the group exists by trying to create it.

If it doesn't, you'll need it anyway, so just run:

sudo groupadd docker

You'll most likely get this response:
groupadd: group 'docker' already exists

2. Add yourself to the group

sudo usermod -aG docker $USER

The variable USER stores your username in your current shell session.
If you want to add some other user, just replace $USER string with their username.

3. Apply changes, by either starting a new shell session (e.g. logout and log back in via SSH) or by simply logging into the new group via:

newgrp docker

Now, you should be able to run docker commands without root privileges! :D
