二、安装步骤

2.1、卸载旧版本的Docker

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

 2.2、安装yum-utils包

2.2.1、下载Docker所需的工具包

yum install -y yum-utils

2.2.2、设置阿里云的Docker镜像仓库 

yum-config-manager \
    --add-repo \
    https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

 2.3、更新yum软件包索引

yum makecache fast

2.4、安装最新版本的Docker Engine和containerd 

yum install docker-ce docker-ce-cli containerd.io

2.5、启动并运行Docker

# 启动Docker
systemctl start docker

# 通过运行hello world镜像验证docker引擎是否已经正确安装
docker run hello-world

# 设置docker开机自启动
systemctl enable docker

# 查看docker的版本号
docker version

# 查看下载的所有镜像
docker images

2.6、配置镜像加速 

# 配置镜像加速器
sudo mkdir -p /etc/docker
 
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": [
	"https://dockerpull.com",
	"https://docker.1panel.live",
	"https://dockerproxy.cn",
	"https://docker.hpcloud.cloud",
	"https://r0xwsghc.mirror.aliyuncs.com",
	"https://dockerhub.azk8s.cn",
	"https://hub-mirror.c.163.com"
  ] 
}
EOF
 
sudo systemctl daemon-reload
 
sudo systemctl restart docker

# 说明：可以同时配置多个镜像加速地址

2.7、查看配置后的镜像

docker info
