1 ), the mirror operation
| operating | command | Explanation |
| Retrieval | docker search keywords eg: docker search redis | We often detailed information on the hub to retrieve the mirror docker, such as mirroring of TAG. |
| Pull | docker pull mirror name: tag | : Tag is optional, tag represents the label, multi-version software, the default is the latest |
| List | docker images | View all local mirror |
| delete | docker rmi image-id | Delete the specified local mirror |
The official website can be used https://hub.docker.com/, the country can use Ali cloud, or Netease cloud.
1. Search Mirror
[root@localhost ~]# docker search mysql
2, pulling the mirror
[root@localhost ~]# docker pull mysql
Pulling specified version mirror
[root@localhost ~]# docker pull mysql:5.5
3. Check all local mirror
[root@localhost ~]# docker images
4, remove the mirror, the mirror according to delete id
Delete commands, [root @ localhost ~] # docker rmi d404d78aa797, according to docker images check out the IMAGE ID to remove the mirror.
2 ), container operations (operating too lazy to make the list, Silicon Valley is still attached to a docker action list instructions)
1, start the container according to the image
[root@localhost ~]# docker run --name mytomcat -d tomcat:latest
Note: - name parameter back to run container custom name (also can not specify a custom name), - d represents the background (behind the mirror parameter name), a colon after the argument as a tag number, such as: latest represent the latest version (last updated version) it can be omitted, I am here to explain it more intuitive added, generally not the latest version tag number must be added to run the container.
2. Check the running container
[root@localhost ~]# docker ps
3, stop the operation of the vessel
[root@localhost ~]# docker stop adc48bc0a25a
[Root @ localhost ~] # docker ps -a # view all containers, including containers has exited, exit status indicates a container for the Exited
It may also be used in accordance with the following command to restart the container CONTAINER ID
[root@localhost ~]# docker start adc48bc0a25a
4, after the container has stopped unnecessary can be deleted by using the following operation order under CONTAINER ID:
[root@localhost ~]# docker rm adc48bc0a25a
Re-use docker ps -a to view all containers will find deleted tomcat container no longer exists
5, the virtual machine container port to port mapping, for example to start a tomcat port mapping of tomcat
[root @ localhost ~] # Docker RUN -d -p 8888 : 8080 tomcat # -d represents the background, -p represents port mapping, which represents a virtual machine port 8888, 8080 represents a container port tomcat
-d : background
-p : the host port is mapped to a port of the host port of the container : the interior of the container port (again)
6, then you can add virtual machines to access tomcat port number through a virtual machine IP, if you can not access your own Baidu linux turn off the firewall or open ports execution.
7, view the boot log container
[Root @ localhost ~] # docker logs 98c3fb8fd426 # view according CONTAINER ID
[root@localhost ~]# docker logs 98c3fb8fd426 14-Sep-2019 15:58:31.313 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Server version: Apache Tomcat/8.5.45 14-Sep-2019 15:58:31.421

Thus, mirror operation Docker operation has concluded and the container is completed by illustrations, of course, many more operations involving more commands refer to reference each image https://docs.docker.com/engine/reference/commandline/docker/ document , here is not a demo, and I was a novice while learning side of the record, there is inadequate please the god of generosity.
