If you see the text, your Docker installation is working! Managing the Docker Service The container is configured to emit a basic “hello world” message and then exit. Once the image has been pulled, a new container will be created from it. As it won’t exist, the image will then get pulled from the Docker Hub repository.

Docker will first look for the hello-world:latest image on your machine. You should see a few lines of output appear in your terminal. Now Docker’s installed, it’s time to test it’s working! You can use the minimal hello-world image.

You should now be able to drop sudo from Docker commands. Alternatively, run the newgrp docker command to immediately login to the updated group. Once you’re in the group, logout and login again. Adding yourself to the docker group will let you use Docker without sudo. This can get tedious if you’re using Docker often. You must usually prefix Docker commands with sudo.
