1. To manage Docker as a non-root user, follow the Docker Post-Installation Steps for Linux instructions. 

2. 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.

 

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

docker run hello-world
