Run the Docker daemon as a non-root user

To create the docker group and add your user:

1. Create the docker group.

   sudo groupadd docker

2. Add your user to the docker group.

   sudo usermod -aG docker $USER

3. Log out and log back in so that your group membership is re-evaluated.

   If you're running Linux in a virtual machine, it may be necessary to restart the virtual machine for changes to take effect.

4. You can also run the following command to activate the changes to groups:

   newgrp docker

5. Verify that you can run docker commands without sudo.

   docker run hello-world
