歡迎使用Openshift - Minishift
OpenShift 是由紅帽公司推出的 PaaS 雲計算平台，供使用者建立網絡應用（App、網站）。
Openshift 目前共提供四種産品：OpenShift Online、OpenShift Enterprise、Openshift Dedicated 和 OpenShift Origin。 其中，OpenShift Online 是面向普通開發者和小微企業的線上公有雲平台；OpenShift Enterprise 是面向企業的私有雲平台；Openshift Dedicated 是面向在AWS/Google Cloud上的私有叢集；OpenShift Origin 是一個開源項目，是構成前兩個的基礎。
OpenShift Enterprise是其私有雲版本這是一個開源軟體，由 OpenShift Origin管理，支援GitHub，開發者可以使用Git來釋出自己的web應用程式到平台上。（source: wiki）
Minishift 是一個可以讓你将 OpenShift Origin 安裝并運作在本地虛拟機上的工具。從原理上講，它就是在虛拟機中運作可配置的 oc cluster up 的過程。是以，他也是在本地運作一個單節點的 OpenShift 叢集，用于做本地開發環境。
安裝指令
// An highlighted block
$ minishift.exe start --vm-driver virtualbox;
安裝成功的輸出：

關閉指令
// An highlighted block
$ minishift stop [flags]
啟動指令
// An highlighted block
$ minishift start --vm-driver virtualbox
$ minishift config set vm-driver virtualbox
删除指令
// An highlighted block
$ minishift delete
$ minishift delete --clear-cache
OC指令
把 oc 指令添加到PATH中
// An highlighted block
$ minishift oc-env // 輸出要添加到PATH中的export指令:
SET PATH=C:\Users\username\.minishift\cache\oc\v3.9.0\windows;%PATH%
REM Run this command to configure your shell:
REM @FOR /f "tokens=*" %i IN ('minishift oc-env') DO @call %i)
$ SET PATH=C:\Users\username\.minishift\cache\oc\v3.9.0\windows;%PATH%
$ oc login -u system:admin
項目和使用者：See a list of Projects & Users
項目清單
// An highlighted block
$ oc get projects
使用者清單
// An highlighted block
$ oc get users
建立使用者，及建立admin使用者
在Web console中直接輸入任何username，即可建立使用者，例如username為administrator：
然後将該使用者加到叢集角色中，角色為cluster-admin
// An highlighted block
$ oc adm policy add-cluster-role-to-user cluster-admin administrator
收集日志 Collect Logs
// An highlighted block
$ minishift start --show-libmachine-logs -v5
檢視插件指令
// An highlighted block
## 使用以下指令檢視目前插件的啟用狀态
$ minishift addon list
## 使用以下指令啟用一個插件，例如我想要啟用 anyuid 插件
$ minishift addon enable anyuid

Openshift 管理
Openshift管理有以下三種途徑：
通過Web Console
通過CLI
OC Tool - Openshift Client
OC 登入：
// An highlighted block
$ oc login
$ oc login -u <username> -p <password>
OC 退出：
// An highlighted block
$ oc logout
通過Rest API Call
// An highlighted block
$ curl -k https://localhost:8443/oapi/v1/projects \
-H "Authorization: Bearer <Token>"
注意：Token有效期為24小時
Token可通過以下指令查詢
// An highlighted block
$ oc login -u developer -p developer //先用developer使用者名登入
$ oc whoami -t
輸出為項目清單的Jason格式，例如
// An highlighted block
$ curl -k https://192.168.99.107:8443/oapi/v1/projects \-H "Authorization: Bearer u-SVoMxAJ2nA1dmUyUsXeW0TIqv62MsDlOibnf6_WsM"
## 輸出為以下格式
{
"kind": "Status",
"apiVersion": "v1",
"metadata": {},
"status": "Failure",
"message": "projects is forbidden: User \"system:anonymous\" cannot list projects at the cluster scope: User \"system:anonymous\" cannot list all projects in the cluster",
"reason": "Forbidden",
"details": {
"kind": "projects"
},
"code": 403
}curl: (6) Could not resolve host: \-H
curl: (3) Port number ended with ' '
好啦，這期就這裡。接着我們會讨論如何在Openshift的項目中添加Application。
