What is the mirror image of Docker

Docker is an open source application container engine that allows developers to package their applications and dependency packages into a portable container, then publish them to any popular Linux machine, or virtualize them. Containers are completely sandboxed and do not have any interface to each other. A complete Docker consists of the following parts:

Docker Client client

Docker Daemon daemon

Docker Image Mirror

Docker Container container

An image is a template, a read-only file that contains the environment and code necessary for the program to run. It uses a hierarchical file system to add each change to the original read-only file in the form of a read-write layer. Mirroring is the cornerstone of container operation. You can obtain the finished image from the image repository. Image repositories can use public repositories (https://hub.docker.com/), or build their own private image repositories.

2. Use and access the official public image repository of Docker

Use the search command to search for images in the repository, such as mysql

Docker search mysql

The results are as follows:

Use the pull command to obtain an image, such as the image of mysql

Docker pull mysql

Create a container using the acquired MySQL image

Docker run-- name my_mysql-p 3306 MYSQL_ROOT_PASSWORD=Welcome_1-d mysql

Use docker ps to view container information

Download another image of Tomcat

Docker search tomcatdocker pull tomcat

Docker images displays the existing images locally.
