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. | |||
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 | |||
