docker虚拟化平台构建

 docker虚拟化平台构建

从1.13版本以后的docker软件分为连个版本：企业版、社区版，在企业中推荐社区版本。

构建docker平台环境，系统选择centos7.x，推荐linux内核3.10

docker平台安装方法如下：

1. 安装第三方epel-relase扩展源

   [root@localhost ~]# yum install epel-release -y

2. 安装docker软件包

   [root@localhost ~]# yum install docker -y

3. 查看docker软件包是否部署

   [root@localhost ~]# yum list docker
   已加载插件：fastestmirror, langpacks
   Loading mirror speeds from cached hostfile
    * base: mirrors.aliyun.com
    * epel: mirrors.tuna.tsinghua.edu.cn
    * extras: mirrors.aliyun.com
    * updates: mirrors.aliyun.com
   已安装的软件包
   docker.x86_64                 2:1.13.1-103.git7f2769b.el7.centos            
   [root@localhost ~]# rpm -qa |grep docker 
   docker-client-1.13.1-103.git7f2769b.el7.centos.x86_64
   docker-1.13.1-103.git7f2769b.el7.centos.x86_64
   docker-common-1.13.1-103.git7f2769b.el7.centos.x86_64

4. 启动docker服务

   systemctl start docker.service

5. 查看docker版本信息，只要看到client和server信息，就说明docker启动正常。

   [root@localhost ~]# docker version
