使用存储库安装

在新主机上首次安装 Docker Engine 之前，您需要设置 Docker 存储库。之后，您可以从存储库安装和更新 Docker。

设置存储库

安装yum-utils包（提供yum-config-manager 实用程序）并设置稳定存储库。

<span style="color:#0c5176 !important"><span style="background-color:#f5f8fa !important"><code> <span style="color:#658b00">sudo </span>yum install <span style="color:#8b008b">-y</span> yum-utils

<span style="color:#555555">$</span> <span style="color:#658b00">sudo </span>yum-config-manager <span style="color:#cd5555">\</span>
    <span style="color:#8b008b">--add-repo</span> <span style="color:#cd5555">\</span>
    https://download.docker.com/linux/centos/docker-ce.repo</code></span></span>

 

安装 Docker 引擎

1. 安装最新版本的 Docker Engine 和 containerd，或者进入下一步安装特定版本：

   <span style="color:#0c5176 !important"><span style="background-color:#f5f8fa !important"><code><span style="color:#555555">$</span> <span style="color:#658b00">sudo </span>yum install docker-ce docker-ce-cli containerd.io</code></span></span>

 启动docker

 sudo systemctl start docker

docker -v 查看版本

设置docker为开机自启动

sudo systemctl enable docker 

docker 配置镜像加速

sudo mkdir -p /etc/docker

sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://yzx9jlvi.mirror.aliyuncs.com"] } EOF

sudo systemctl daemon-reload

sudo systemctl restart docker
