# 我的第一個雲端軟體 - NodeRED

## 1. 建立 "NodeRED" app

step 1: Login IBM Cloud https://cloud.ibm.com/login
step 2: 點選 "型錄" , 然後在左邊的選單中, 點選 "軟體" 後,再勾選 "入門範本套件", 就可以看到 Node-RED APP 範本套件 .
step 3: 點選 "Node-RED APP" 範本套件. "選取地區" 用預設值 "達拉斯", "定價方案" 點選 "精選". 使用預設的名稱(此名稱必須是"唯一"),然後點選右邊的 "建立" 按鈕.

## 2 部署 "NodeRED" app
step 1: 點選右邊的 "部屬您的應用程式" 按鈕
step 2: 部屬目標點選 "Cloud Foundry"
step 3: 點選建立 "IBM Cloud API 金鑰", 新建含有完整存取權的API金鑰, 並點選 "確定".
step 4: 往下拉並點選 "下一頁", 開始配置配屬自動化服務.
step 5: 點選 "Delivery Pipelines" 開始部署應用程式.
step 6: 等待部署完畢後, 開啟儀表板, 下拉 Cloud Foundry 應用程式並點選剛建立好的應用程式.
step 7: 點選頁面上方的 "訪問應用程式URL" 連結
step 8: 待 NodeRED 主控台顯示後, 點選 "下一頁", 並輸入 "Username" 及 "Password", 並點選 "Next" 按鈕. (請記下登入帳號及密碼) 避免日後忘記無法登入.
step 9: 點選 "Finish" 按鈕
step 10: 點選 "Get your Node-Red flow editor" 並輸入帳號及密碼, 登錄到 Node-Red 流程編輯器.

## 3. 設計/部署 IoT 流程
step 1: 登入 NodeRED 編輯器
step 2: 點選右邊的下拉式選單, 點選 "節點管理", 點選 "安裝" 頁面, 並搜尋 "ibmiot", 再安裝該程式.
step 3: 點選右邊的下拉式選單, 點選 "匯入", 將下列程式碼貼入對話框中, 點選 "新流程", 再點選 "匯入" 按鈕.
