本文要做什么？
很多为了验证应用在 OpenShift 平台的行为是否正常，或者组成一个简单的开发环境，直接搭建一个 OpenShift/Origin 环境可能太重了，而且运行在本机可能占用内存也太多。此时使用 MiniShift 来组成自己的开发环境就比较合适了。
本文就简单介绍下如何配置 MiniShift 环境，无论是 Windows/Linux/MacOS都是可以安装的，前提是你需要安装个虚拟机软件 virtualbox。此处将以笔者 Linux 开发环境进行演示，操作大同小异可供参考。
安装 Minishift
官方 Github Relese Page https://github.com/minishift/minishift/releases，
cd ~/Downloads
#下载v1.34.3 minishift
wget https://github.com/minishift/minishift/releases/download/v1.34.3/minishift-1.34.3-linux-amd64.tgz
#解压到/usr/bin目录下
sudo tar zxvf minishift-1.34.3-linux-amd64.tgz -C /usr/bin
#验证是否能执行，有版本输出即正常
minishift version
#添加自动补全，重开shell自动提示即正常
sudo minishift completion bash > /etc/bash_completion.d/minishift
对于 Win 环境，将下载的 zip 包解压到任意目录，然后将minishift.exe添加环境变量Path中即可，Win下自动补全功能好像没有。
安装 virtualbox
官方下载地址 https://www.virtualbox.org/wiki/Downloads
根据自己的平台下载安装即可。
简易搭建docker registry
注意，请提前规划好docker registry端口号，配置到docker上再重启docker服务。
docker run --name myRegistry --restart=always -d -p 5000:5000 registry
webUI 可以参考 CSDN 胡了了 的博客 https://blog.csdn.net/huqigang/article/details/76655854
搭建 Gitea
基于 docker-compose 搭建 Gitea 用于 Minishift 上传代码构建镜像。
gitea/docker-compose.yml
version: "3"
networks:
gitea:
external: false
services:
server:
image: gitea/gitea:1.15.6
container_name: gitea
environment:
- USER_UID=1000
- USER_GID=1000
restart: always
networks:
- gitea
volumes:
- ./gitea:/data
- /etc/timezone:/etc/timezone:ro
- /etc/localtime:/etc/localtime:ro
ports:
- "3000:3000"
- "222:22"
启动 Gitea
cd gitea
docker-compose up -d
启动完成后，访问 3000 新建用户即可使用。
配置与启动 Minishift
以下命令依次执行，内存、CPU、硬盘、非安全docker仓库按需配置即可。
#设置虚拟机驱动
minishift config set vm-driver virtualbox
#设置openshift版本
minishift config set openshift-version 3.11.0
#设置虚拟机cpu核数
minishift config set cpus 2
#设置虚拟机内存
minishift config set memory 9GB
#设置虚拟机磁盘大小
minishift config set disk-size 20GB
#设置docker registry仓库地址，刚才创建的那个
minishift config set insecure-registry 192.168.99.1:5000
#设置镜像缓存，方便删除集群后再创建，不需要再重新拉镜像（不开以后再拉较慢）
minishift config set image-caching true
#启用管理员用户插件
minishift addon enable admin-user
#启用任意用户uid，不设置会导致自定义镜像部署时用户设置不正常
minishift addon enable anyuid
#设置静态ip，也可以不设置
minishift ip --set-static
启动 Minishift
#启动minishift，等待初始化完成，首次初始化较慢

Server Information ...
OpenShift server started.
The server is accessible via web console at:
https://192.168.99.115:8443/console
此时直接访问输出的地址就能访问平台了，最好先执行下边的命令再进平台。
启动后配置命令：
#启用admin用户
minishift addons apply admin-user
#启用任意用户uid，允许pod使用root用户运行（便于调试）
minishift addons apply anyuid
访问 Minishift WebUI，那个 console 地址（本例中为https://192.168.99.115:8443/console），使用 developer 和任意密码即可登录。
可以使用默认的 My Project 也可以自己新建，这里使用默认的就行。
到这个熟悉的 OpenShift 界面就可以了。除了 logo 不大一样，其余功能都差不多。
马上更新自定义OpenShift镜像，静请期待！
