1.背景:
基于虚拟机,centeros7系统部署
2.清理docker(如果不是第一次安装)
yum remove docker
docker-client
docker-client-latest
docker-common
docker-latest
docker-latest-logrotate
docker-logrotate
docker-engine
3.部署docker相关依赖
#1.需要的安装包
yum install -y yum-utils
#2.更换Docker国内源仓库
yum-config-manager
--add-repo
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
#3.更新软件包索引
yum makecache fast
#4.安装Docker引擎 docker-ce 社区版、docker-ee 企业版
yum install -y docker-ce docker-ce-cli containerd.io
#5.启动Docker
systemctl start docker
#6.查看docker version

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
