详述GBase 8c容器化部署（一）

Docker是一个开源的应用容器引擎，适用于应用的自动化打包和发布、服务器中部署数据库及其他后台应用等场景。GBase 8c 通用管理平台（简称为：GBase 8c Platform）结合Docker，实现了容器化部署方式，其优势在于：1）可移植性，使得GBase 8c Platform能够与更多软硬件环境适配；2）一致性，不易出现文件丢包问题；3）部署 *** 作更为便捷简易。

 Docker安装

（1）检查安装

检查Docker是否已安装，以及核对是否在推荐版本范围内。

[root@gbase8c ~]# docker -v

如已安装Docker且返回版本信息，如下所示：

Docker version 1.13.1, build 64e9980/1.13.1

如未安装Docker，则显示命令错误：

-bash: docker: command not found

（2）安装Docker

如服务器没有安装其他版本的Docker，则可直接使用yum命令进行安装。

[root@gbase8c ~]# yum install -y docker.x86_64
