Centos下安装docker教程

$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
  latest: Pulling from hello-world

  hello-world:latest: The image you are pulling has been verified. Important: image verification is a tech preview feature and should not be relied on to provide security.
  Digest: sha256:aa03e5d0d5553b4c3473e89c8619cf79df368babd1.7.1cf5daeb82aab55838d
  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.
      (Assuming it was not already locally available.)
   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
