# docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world d1725b59e92d: Pull complete Digest: sha256:0add3ace90ecb4adbf7777e9aacf18357296e799f81cabc9fde470971e499788 Status: Downloaded newer image for hello-world:latest Hello from Docker! This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps:  1. 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 which runs the     executable that produces the output you are currently reading.  4. The Docker daemon streamed that output to the Docker client, which sent it     to your terminal. To try something more ambitious, you can run an Ubuntu container with:  $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID:  https://hub.docker.com/ For more examples and ideas, visit:  https://docs.docker.com/get-started/
