1. Install dockerbrew cask install docker2 under docker,mac. Check whether docker has successfully installed docker-- versionDocker version 19.03.13, build 4484c46d9d3. Add a domestic mirror source for docker.

Edit: ~ / .docker/daemon.json, add the following, and then restart.

"registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"]4." Create a base environment image and open a container with this image.

In docker, a mirror is like the concept of a class in java, and a container is an object created with an image.

Docker images # checks all existing images. Docker run-it-- name centos centos:latest / bin/bash# create a docker image with centos as the core # docker run command launches a docker container #-it refers to the interactive mode #-name defines the container name # centos:latest is the specific image name and image tag, and defaults to the local docker image library. If the local mirror library does not exist, it will look on docker hub for # / bin/bash is the command running in interactive mode. After running the above code, it will enter the interior of the container.
