本文要做什麼？
很多為了驗證應用在 OpenShift 平臺的行為是否正常，或者組成一個簡單的開發環境，直接搭建一個 OpenShift/Origin 環境可能太重了，而且執行在本機可能佔用記憶體也太多。此時使用 MiniShift 來組成自己的開發環境就比較合適了。
本文就簡單介紹下如何配置 MiniShift 環境，無論是 Windows/Linux/MacOS都是可以安裝的，前提是你需要安裝個虛擬機器軟體 virtualbox。此處將以筆者 Linux 開發環境進行演示，操作大同小異可供參考。
安裝 Minishift
官方 Github Relese Page https://github.com/minishift/minishift/releases，
cd ~/Downloads
#下載v1.34.3 minishift
wget https://github.com/minishift/minishift/releases/download/v1.34.3/minishift-1.34.3-linux-amd64.tgz
#解壓到/usr/bin目錄下
sudo tar zxvf minishift-1.34.3-linux-amd64.tgz -C /usr/bin
#驗證是否能執行，有版本輸出即正常
minishift version
#新增自動補全，重開shell自動提示即正常
sudo minishift completion bash > /etc/bash_completion.d/minishift
對於 Win 環境，將下載的 zip 包解壓到任意目錄，然後將minishift.exe新增環境變數Path中即可，Win下自動補全功能好像沒有。
安裝 virtualbox
官方下載地址 https://www.virtualbox.org/wiki/Downloads
根據自己的平臺下載安裝即可。
簡易搭建docker registry
注意，請提前規劃好docker registry埠號，配置到docker上再重啟docker服務。
docker run --name myRegistry --restart=always -d -p 5000:5000 registry
webUI 可以參考 CSDN 胡了了 的部落格 https://blog.csdn.net/huqigang/article/details/76655854
搭建 Gitea
基於 docker-compose 搭建 Gitea 用於 Minishift 上傳程式碼構建映象。
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"
啟動 Gitea
cd gitea
docker-compose up -d
啟動完成後，訪問 3000 新建使用者即可使用。
配置與啟動 Minishift
以下命令依次執行，記憶體、CPU、硬碟、非安全docker倉庫按需配置即可。
#設定虛擬機器驅動
minishift config set vm-driver virtualbox
#設定openshift版本
minishift config set openshift-version 3.11.0
#設定虛擬機器cpu核數
minishift config set cpus 2
#設定虛擬機器記憶體
minishift config set memory 9GB
#設定虛擬機器磁碟大小
minishift config set disk-size 20GB
#設定docker registry倉庫地址，剛才建立的那個
minishift config set insecure-registry 192.168.99.1:5000
#設定映象快取，方便刪除叢集后再建立，不需要再重新拉映象（不開以後再拉較慢）
minishift config set image-caching true
#啟用管理員使用者外掛
minishift addon enable admin-user
#啟用任意使用者uid，不設定會導致自定義映象部署時使用者設定不正常
minishift addon enable anyuid
#設定靜態ip，也可以不設定
minishift ip --set-static
啟動 Minishift
#啟動minishift，等待初始化完成，首次初始化較慢

Server Information ...
OpenShift server started.
The server is accessible via web console at:
https://192.168.99.115:8443/console
此時直接訪問輸出的地址就能訪問平臺了，最好先執行下邊的命令再進平臺。
啟動後配置命令：
#啟用admin使用者
minishift addons apply admin-user
#啟用任意使用者uid，允許pod使用root使用者執行（便於除錯）
minishift addons apply anyuid
訪問 Minishift WebUI，那個 console 地址（本例中為https://192.168.99.115:8443/console），使用 developer 和任意密碼即可登入。
可以使用預設的 My Project 也可以自己新建，這裡使用預設的就行。
到這個熟悉的 OpenShift 介面就可以了。除了 logo 不大一樣，其餘功能都差不多。
馬上更新自定義OpenShift映象，靜請期待！
