Azure Terraform（九）利用 Azure DevOps Pipeline 的审批，控制流程发布

2022-01-13 23:31:13 作者：互联网

一，引言

　　Azure Pipeline 管道是一个自动化过程；但是往往我们由于某种原因，需要在多个阶段之前获得批准之后再继续下一步流程，所以我们可以向Azure Pipeline 管道添加审批！批准流程可帮助我们进一步控制自己的管道；我们可以控制管道内特定阶段的 Step 开始，通过审批，并决定 Azure Pipeline 管道何时完成。

而至于为什么要添加审批流程，是因为基础设施资源的部署是需要进行评估，慎重操作。有了审批，可以查看前一阶段以确认配置代码是否正确。

二，正文

1，Azure DevOps 创建新的项目

输入项目描述等信息

Project name：“Terraform_CnBateBlogWeb_AutoDeploy”

Visibility 选择：“Private” ----- （根据现有项目进行设置）

Version control 选择 “Git”

Work item process：“Agile”

确认完以上信息，点击 “Create” 进行创建。

2，配置Azure DevOps 审批

选择左侧菜单 ”Pipelines =》Environments“，点击 ”Create environment“ 创建环境

输入配置以下参数

Name：”Approve_AutoDeploy"

Resoure 选择：“None” （默认即可）

点击 “Create” 创建环境

接下来为当前 “Approve_AutoDeploy” 环境创建审批

点击红色箭头所指，选择 “Approve and checks” 添加审批请求

选择 "Approvals" ，并将自己设置为申请人

添加完成后，可看到类型为 “Approvals” 的记录，大家需要注意的是，审批的过期时间默认是 “30天”，大家可以根据实际情况更改。

3，配置 Azure DevOps Pipeline

选择左侧菜单 “Pipelines”，点击 “Create Pipeline“ 创建管道作业

今天不使用经典编辑器模式，而选择 GitHub (yaml)

选择对应的 TF Code 的代码仓库

选择 “Start Pipeline” 开启新的管道构建部署代码

Azure DevOps 会为我们自动在项目根目录生成一个名称叫 “azure-pipelines.yaml” 的文件，我们将定义好的管道步骤添加到该文件中

管道步骤审批 yaml 示例代码

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

注意：我将在 terraform_apply 阶段之前添加一个申请请求

红色标记是需要改成自己Azure的订阅，

橙色标记是需要添加的变量：

　　1，管道变量：tf_version

　　2，秘密变量：terraform_rg，storage_account，storage_account_container，container_key，keyvault，keyvault_sc
