Docker的官网 https://www.docker.com/  
Developers的下面有docs

Get docker 中有安装docker

安装docker  
注意要加上sudo 代表为root用户

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

安装依赖包

sudo yum install -y yum-utils \
      device-mapper-persistent-data \
      lvm2

安装过程中出现如下的报错，

Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=vag error was
    14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error"

百度查一下报错，原因是虚拟机没有连上网

此时ping百度也是ping不通的。

解决方法  
使用 vagrant reload 重启虚拟机即可  
![20200727080527611.png][]  
设置阿里云的docker仓库地址， 视频中使用的是官方的仓库地址，下载较慢。

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

安装docker  
`sudo yum install docker-ce docker-ce-cli containerd.io`  
启动docker  
`sudo systemctl start docker`  
设置docker 开机自启  
sudo systemctl enable docker

配置docker 阿里云镜像加速

依次复制如下的四条命令， 进行阿里云的docker的镜像加速

sudo mkdir -p /etc/docker
    sudo tee /etc/docker/daemon.json <<-'EOF'
    {
      "registry-mirrors": ["https://pyxksa0p.mirror.aliyuncs.com"]
    }
    EOF
    sudo systemctl daemon-reload
    sudo systemctl restart docker
