安装依赖包

yum install -y yum-utils \
       device-mapper-persistent-data \
       lvm2
       
yum-config-manager \
--add-repo \
https://mirrors.ustc.edu.cn/docker-ce/linux/centos/docker-ce.repo     

sed -i 's/download.docker.com/mirrors.ustc.edu.cn\/docker-ce/g' /etc/yum.repos.d/docker-ce.repo

yum-config-manager --enable docker-ce-test

yum-config-manager --enable docker-ce-nightly

安装 Docker CE

yum makecache fast

yum install -y docker-ce

使用脚本自动安装

curl -fsSL get.docker.com -o get-docker.sh

vi /usr/lib/systemd/system/docker.service

# 镜像存放地址改为：/home/docker/lib
ExecStart=/usr/bin/dockerd --graph=/home/docker/lib -H fd:// --containerd=/run/containerd/containerd.sock

启动 Docker CE

systemctl enable docker
systemctl start docker

建立 Docker 用户组

groupadd docker
usermod -aG docker $USER

测试 Docker 是否安装正确

docker run hello-world

登陆 Docker 账号

docker login --username=xxxxx --password='xxxxx' hub.baidubce.com
