Docker安装

CentOS操作系统：

yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

yum install -y yum-utils
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sed -i 's+https://download.docker.com+https://mirrors4.tuna.tsinghua.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo

yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

systemctl start docker
systemctl enable docker

PS：镜像加速现在也没啥必要配了，基本上被墙完了，.
