Remove the mirror from docker:
The first step: stop the container, docker stop the CONTAINER ID of the container or the NAMES of the container. (Note: Check if there is a repetition and determine the value to be stopped)
For example: docker stop mysql instance uses NAMES
Step 2: Remove the container, the CONTAINER ID of the docker rm container or the NAMES of the container
For example: docker rm c7109f74d339 instance uses CONTAINER ID
Step 3: View and remove the image, docker images (function: view image).
The IMAGE ID of the docker rmi image or the REPOSITORY of the image (Note: whether the IMAGE ID is duplicated, if there is duplicate, it is recommended to use REPOSITORY)
For example: docker rmi docker.io/hello-world instance uses REPOSITORY.
If there is a label written by the user during installation on the container , you can use: docker rmi docker.io/mysql:5.7
Force removal: use -f or --force. You can remove the image regardless of the container reference, but I think this method is not safe.
Docker container removal:
View all containers: docker ps -a displays all running, Exited, and Created containers
Remove the container: command one, docker rm $(docker ps -a -q); command two, docker rm $(docker ps -qf status=status value);
Command 3: docker container prune (docker1.13)
