自动安装docker:

1.dockerfile的配置：

Vagrant.require_version ">= 1.6.0"

boxes = [
    {
        :name => "docker-host",
        :eth1 => "192.168.205.10",
        :mem => "1024",
        :cpu => "1"
    }
]
Vagrant.configure("2") do |config|

  config.vm.box = "centos7"
  config.vm.provision "shell", inline: <<-SHELL

  sudo yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine
  sudo yum install -y yum-utils device-mapper-persistent-data lvm2
  sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
  #注意要-y 默认安装，否则dokcer 安装有上.:花了半小时才明白
  sudo yum install -y docker-ce docker-ce-cli containerd.io
  sudo systemctl start docker
  SHELL
end
