# list all local images, and then add grep filtering query, such as docker images | grep mysqldocker images# finds relevant images on Docker Hub. For example, you need to check mysql-related images docker search mysql# to list all local container information docker ps-a # Delete local images docker rmi images ID# delete local containers docker rm container ID# get images from docker hub For example, to get the mysql5.6 image # is actually going to https://hub.docker.com/ to obtain the mysql image, and the tag is that 5.6docker pull mysql:5.6# uses the image to start (run) a container #-I keep the container's standard input open #-t assign a terminal to the docker and bind it to the container's standard input #-d let the container backend run #-p container port and native port mapping The first port is the native port, and the second is the container port #-v the native directory is mounted to the container directory docker run-d-p 127.0.0.1 docker exec 3306 it 3306 mysql:5.6# into a container terminal running in the background, it container ID / bin/bash# starts the stopped container docker start container ID# stops the container docker stop container ID# restarts a container docker restart container ID to this I believe that you have a deeper understanding of "the method of installing Docker under cnetos7 and what are the common commands of docker".
