The Docker client contacted the Docker daemon.2. The Docker daemon pulled the "hello-world"image from the Docker Hub.(amd64)3. The Docker daemon created a new container from that image whichruns theexecutable that produces the output you are currently reading.4. The Docker daemon streamed that output to the Docker client, whichsent itto your terminal.To try something moreambitious, you can run an Ubuntu container with:$ docker run -it ubuntu bashShare images, automate workflows, and morewith a freeDocker ID:https://hub.docker.com/For moreexamples and ideas, visit:https://docs.docker.com/get-started/
