Docker 基础命令学习

Docker 一键安装命令

curl -fsSLo- get.docker.com | /bin/sh

国内使用阿里云镜像

wget get.docker.com -O get.docker.sh
bash  get.docker.sh  --mirror Aliyun

This message shows that your installation appears to be working correctly.

To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

# 运行一个 Ubuntu 容器
docker run -it ubuntu bash

# 显示所有的容器
docker ps -a

# 显示本机镜像
docker images
