一、pouch镜像简介

阿里巴巴正式开源了基于Apache 2.0协议的容器技术Pouch。Pouch是一款轻量级的容器技术，拥有快速高效、可移植性高、资源占用少等特性，主要帮助阿里更快的做到内部业务的交付，同时提高超大规模下数据中心的物理资源利用率。

二、pouch镜像配置方法（基于CentOS 7系统配置）

1、查看主机名

[root@centos ~]# hostnamectl
   Static hostname: centos
         Icon name: computer-vm
           Chassis: vm
        Machine ID: f6fc8fb7991c4c518238af7c75f16046
           Boot ID: a5342490e7fd4891978ea3b2e7e0aaf1
    Virtualization: vmware
  Operating System: CentOS Linux 7 (Core)
       CPE OS Name: cpe:/o:centos:centos:7
            Kernel: Linux 3.10.0-1160.el7.x86_64
      Architecture: x86-64
[root@centos ~]#

2、添加镜像文件

[root@centos ~]# vim /etc/yum.repos.d/pouch-centos7.repo
[root@centos ~]# cat /etc/yum.repos.d/pouch-centos7.repo
[pouch-stable]
name=Pouch Stable - $basearch
baseurl=http://mirrors.aliyun.com/opsx/pouch/linux/centos/7/$basearch/stable
enabled=1
gpgcheck=1
gpgkey=http://mirrors.aliyun.com/opsx/pouch/linux/centos/gpg

[pouch-test]
name=Pouch Test - $basearch
baseurl=http://mirrors.aliyun.com/opsx/pouch/linux/centos/7/$basearch/test
enabled=0
gpgcheck=1
gpgkey=http://mirrors.aliyun.com/opsx/pouch/linux/centos/gpg
[root@centos ~]#

3、更新YUM源

将软件包信息提前在本地索引缓存 ，用来提高搜索安装软件的速度,建议执行这个命令可以提升yum安装的速度

[root@centos ~]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: base extras pouch-stable updates
Cleaning up list of fastest mirrors
Other repos take up 145 M of disk space (use --verbose for details)
[root@centos ~]# yum makecache
