azure - Azure DevOps 管道中的条件阶段执行

Question

我希望根据前一阶段中设置的变量内容来执行 Azure DevOps 管道中的一个阶段。

这是我的管道:

stages:
  - stage: plan_dev
    jobs:
    - job: terraform_plan_dev
      steps:
      - bash: echo '##vso[task.setvariable variable=terraform_plan_exitcode;isOutput=true]2'
        name: terraform_plan

  - stage: apply_dev
    dependsOn: plan_dev
    condition: eq(stageDependencies.plan_dev.terraform_plan_dev.outputs['terraform_plan.terraform_plan_exitcode'], '2')
    jobs:
    - deployment: "apply_dev"
      ...

我们的想法是，如果 plan_dev 阶段没有显示任何更改，则跳过 apply_dev 阶段。背景是，我们在 plan_dev 阶段对部署进行了手动批准，如果没有需要批准的更改，我们希望跳过该阶段。

不幸的是，这似乎不起作用。无论变量 terraform_plan_exitcode 是否设置为预期值 (2)，apply_dev 阶段都会被跳过。

对于语法，我遵循 documentation here上面写着:

stageDependencies.StageName.JobName.outputs['StepName.VariableName']

我也看到过同样的问题。您需要使用依赖项变量而不是 stageDependencies:

stages:
- stage: plan_dev
jobs:
- job: terraform_plan_dev
  steps:
  - bash: echo '##vso[task.setvariable variable=terraform_plan_exitcode;isOutput=true]2'
    name: terraform_plan

- stage: apply_dev
dependsOn: plan_dev
condition: eq(dependencies.plan_dev.outputs['terraform_plan_dev.terraform_plan.terraform_plan_exitcode'], '2')
jobs:
- deployment: "apply_dev"

以下是我使用 Terraform Plan + 条件应用的更完整示例:

stages: 
  - stage: Build_zip_plan
    displayName: Build portal, zip files and terraform plan
    jobs:
    - job: Build_portal_zip_files_terraform_plan

        vmImage: 'ubuntu-latest'
      steps:
        - task: Cache@2
          displayName: 'Register TF cache'
          inputs:
            key: terraform | $(Agent.OS) | $(Build.BuildNumber) | $(Build.BuildId) | $(Build.SourceVersion) | $(prefix)
            path: ${{ parameters.tfExecutionDir }}

        - task: TerraformInstaller@0
          displayName: 'Install Terraform'
          inputs:
            terraformVersion: ${{ parameters.tfVersion }}

        - task: TerraformTaskV1@0
          displayName: 'Terraform Init'
          inputs:
