Mirror operation

Look at the mirror image 

[[email protected] ~]$  docker images
REPOSITORY   TAG       IMAGE ID   CREATED   SIZE

Download mirroring （ Timeout error ）

[[email protected] ~]$ docker pull hello-world
Using default tag: latest
Error response from daemon: Get "https://registry-1.docker.io/v2/": net/http: TLS handshake timeout

Specifies that the image is pulled again 

[[email protected] ~]$ sudo vi /etc/docker/daemon.json
[[email protected] ~]$ cat /etc/docker/daemon.json
{
    "registry-mirrors":["https://docker.mirrors.ustc.edu.cn"]
}

Container operation 

####  Look at all the containers 
[[email protected] ~]$ docker ps -a
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES

Create a container 

[[email protected] ~]$ docker create -it --name=test hello-world
aaa8f6652052d88c159e53ac9f88cbfa77934c8f7b31a615ec9f18acedb88f1e
[[email protected] ~]$ docker ps -a
CONTAINER ID   IMAGE         COMMAND    CREATED         STATUS    PORTS     NAMES
aaa8f6652052   hello-world   "/hello"   8 seconds ago   Created             test

Start the container 

[[email protected] ~]$ docker start aaa8f6652052
aaa8f6652052
[[email protected] ~]$ docker ps -a
CONTAINER ID   IMAGE         COMMAND    CREATED          STATUS                     PORTS     NAMES

Check the log 

[[email protected] ~]$ docker logs aaa8f6652052

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
