1）添加 docker 的软件源
[root@docker ~]#curl -s -o /etc/yum.repos.d/docker-ce.repo https://download.docker.com/linux/centos/docker-ce.repo
2）查看现有的 docker 版本
[root@docker ~]#yum list docker-ce --showduplicates | sort -r
3）安装指定的 docker 版本
[root@docker ~]#yum -y install docker-ce-20.10.24 docker-ce-cli-20.10.24 containerd.io docker-compose-plugin
4） 配置 docker 的镜像加速
参考链接:
# https://www.runoob.com/docker/docker-mirror-acceleration.html
[root@docker ~]#mkdir -p /etc/docker
[root@docker ~]#tee /etc/docker/daemon.json <<-'EOF'
> {
> "registry-mirrors": ["https://tuv7rqqq.mirror.aliyuncs.com","https://docker.mirrors.ustc.edu.cn/","https://hub-mirror.c.163.com/","https://reg-mirror.qiniu.com"]
> }
> EOF
[root@docker ~]#systemctl daemon-reload
[root@docker ~]#systemctl enable --now docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
[root@docker ~]#docker version
5） 新手必备自动补全功能
[root@docker ~]#yum -y install bash-completion
[root@docker ~]#source /usr/share/bash-completion/bash_completion
6） 彩蛋
[root@docker ~]#docker run --restart unless-stopped -dp 80:80 jasonyin2020/oldboyedu-games:v0.4
7）windows 添加hosts解析
