You run this command:
docker run -it ubuntu bash
docker: Got permission denied while trying to connect to the Docker daemon sockes/create: dial unix /var/run/docker.sock: connect: permission denied.
You do not want to run a Docker container as a privileged user (as a recommended practice). What should you do?

Install Docker. If you need assistance, see this posting.
1. Run these commands:
sudo newgrp docker exit sudo usermod -aG docker jdoe # Replace "jdoe" with the user you want to run the Docker container with. You can use "whoami" manually to find out what user you are.
2. If you were logged in as jdoe (the user you just added), log out and log back in.
3. Now try again (e.g., run
docker run -it ubuntu bash).
