Azure Terraform(九)利用 Azure DevOps Pipeline 的審批來控制流程釋出

Grant_Allen發表於2022-01-13

一,引言

  Azure Pipeline 管道是一個自動化過程;但是往往我們由於某種原因,需要在多個階段之前獲得批准之後再繼續下一步流程,所以我們可以向Azure Pipeline 管道新增審批!批准流程可幫助我們進一步控制自己的管道;我們可以控制管道內特定階段的 Step 開始,通過審批,並決定 Azure Pipeline 管道何時完成。

而至於為什麼要新增審批流程,是因為基礎設施資源的部署是需要進行評估,慎重操作。有了審批,可以檢視前一階段以確認配置程式碼是否正確。

二,正文

1,Azure DevOps 建立新的專案

登入 Azure DevOps 的地址:https://www.dev.azure.com ,點選 “+ New project” 建立新的專案

輸入專案描述等資訊

Project name:“Terraform_CnBateBlogWeb_AutoDeploy”

Visibility 選擇:“Private” ----- (根據現有專案進行設定)

Version control 選擇 “Git”

Work item process:“Agile”

確認完以上資訊,點選 “Create” 進行建立。

2,配置Azure DevOps 審批

選擇左側選單 ”Pipelines =》Environments“,點選 ”Create environment“ 建立環境

輸入配置以下引數

Name:”Approve_AutoDeploy"

Resoure 選擇:“None” (預設即可)

點選 “Create” 建立環境

接下來為當前 “Approve_AutoDeploy” 環境建立審批

點選紅色箭頭所指,選擇 “Approve and checks” 新增審批請求

選擇 "Approvals" ,並將自己設定為申請人

新增完成後,可看到型別為 “Approvals” 的記錄,大家需要注意的是,審批的過期時間預設是 “30天”,大家可以根據實際情況更改。

3,配置 Azure DevOps Pipeline 

選擇左側選單 “Pipelines”,點選 “Create Pipeline“ 建立 管道作業

今天不使用經典編輯器模式,而選擇 GitHub (yaml)

選擇對應的 TF Code 的程式碼倉庫

選擇 “Start Pipeline” 開啟新的管道構建部署程式碼

Azure DevOps 會為我們自動在專案根目錄生成一個名稱叫 “azure-pipelines.yaml” 的檔案,我們將定義好的管道步驟新增到該檔案中

管道步驟審批 yaml 示例程式碼

jobs:
    - deployment: terraform_apply
      continueOnError: false
      environment: 'Approve_Production'
      timeoutInMinutes: 120
      strategy:
       runOnce:
        deploy:
            steps:

注意:我將在 terraform_apply 階段之前新增一個申請請求

紅色標記是需要改成自己Azure的訂閱,

橙色標記是需要新增的變數:

  1,管道變數:tf_version

  2,祕密變數:terraform_rg,storage_account,storage_account_container,container_key,keyvault,keyvault_sc 

  1 # Starter pipeline
  2 # Start with a minimal pipeline that you can customize to build and deploy your code.

新增祕密變數,點選 “ Variables=》New variable”

輸入機密的名稱和值

Name:“terraform_rg”

Value:“Web_Test_TF_RG”

點選 “OK” 確認新增操作

 按照以上方式一次新增以下機密資訊

terraform_rg:"Web_Test_TF_RG"

storage_account:"cnbatetfstorage"

storage_account_container:"tf-state001"

container_key:"cnbate.tf.stats"

keyvault:"cnbate-terraform-kv001"

keyvault_sc:"terraform-stste-storage-key"

完成以上資訊後,點選 ”Run” 手動觸發當前 Pipeline

選擇分支 ‘“remote_stats”,點選 “Run”

接下來我們就會看到整個流程步驟,以及當前執行執行的步驟,如果需要審批,流程就會暫停,等待審批完成後,再執行後續操作

點選 “Approve” 同意審批,進行下一步執行 TF Code 執行部署計劃

OK,成功!!!部署完成。是✨?ヾ(≧▽≦*)o

三,結尾

   對於今天實驗的操作,大家可以多多練習,參考作者的 github 倉庫。今天的內容需要在Azure DevOps 上進行操作的,大家要多加練習。至於 Terraform 程式碼方面沒有過多的講解,主要是因為結合之前部署Azure 資源,大家都會Terraform 有了一定的理解了。所以大家可以自行下載,進行分析修改。
