docker run hello-world

admin

使用docker来测试一下Hello-World，通过输入docker pull hello-world来拉取hello-world镜像,或者直接：sudo docker run hello-world

1. lishimin@tang:~$ sudo docker run hello-world
   
2. Unable to find image 'hello-world:latest' locally
   
3. latest: Pulling from library/hello-world
   
4. 1b930d010525: Pull complete
   
5. Digest: sha256:b8ba256769a0ac28dd126d584e0a2011cd2877f3f76e093a7ae560f2a5301c00
   
6. Status: Downloaded newer image for hello-world:latest

8. Hello from Docker!
   
9. This message shows that your installation appears to be working correctly.
   
10. 
    
11. To generate this message, Docker took the following steps:
    
12. 1. The Docker client contacted the Docker daemon.
    
13. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    
14.     (amd64)
    
15. 3. The Docker daemon created a new container from that image which runs the
    
16.     executable that produces the output you are currently reading.
    
17. 4. The Docker daemon streamed that output to the Docker client, which sent it
    
18.     to your terminal.
    
19. 
    
20. To try something more ambitious, you can run an Ubuntu container with:
    
21. $ docker run -it ubuntu bash
    
22. 
    
23. Share images, automate workflows, and more with a free Docker ID:
