1、设置Docker存储库
- 设置后可以从存储库安装和更新Docker
1、安装所需的包
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
2、设置稳定存储库
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
2、安装Docker CE
- 安装最新版Docker
sudo yum install docker-ce docker-ce-cli containerd.io
3、使用阿里云Docker镜像加速
-
获取加速器地址
阿里云加速器 - 配置本机Docker镜像
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://xxxxxx.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
4、运行HelloWorld
docker run hello-world
//本地没找到，到远程库获取
