Question

我想不出一个解决方案，当Terraform返回退出代码2时，我将继续ADO Pipeline构建。无论是否检测到更改，Terraform通常返回退出代码0，但使用-deteailed-exitcode附在plan命令上：退出代码0不变，退出代码2不变。

我面临的问题是，如果管道没有计划的地形变更，那么管道将跳过其余阶段并报告成功，如果检测到变更，将继续在管道上运行。

      - script: |
        terraform plan -input=false -no-color -out=plan.tfplan -detailed-exitcode
        # on changes detected, succeed; otherwise fail
        if [ $? -eq 2 ]; then 
          exit 0
        else
          exit 1
        fi
      displayName: "Planning Terraform Changes"
      name: TerraformPlan
      condition: succeeded()
      continueOnError: true
      workingDirectory: "$(Build.SourcesDirectory)/terraform/$(ENVIRONMENT_NAME)"
      env:
        TF_IN_AUTOMATION: true
        ARM_CLIENT_ID: $(NONPROD_ARM_CLIENT_ID)
        ARM_CLIENT_SECRET: $(NONPROD_ARM_CLIENT_SECRET)
        ARM_SUBSCRIPTION_ID: $(NONPROD_ARM_SUBSCRIPTION_ID)
        ARM_TENANT_ID: $(NONPROD_ARM_TENANT_ID)
    - script: |
        echo "Nothing to do"
      displayName: "No changes detected"
      name: NoChanges
      condition: failed()
    - script: |
        echo "Changes detected"
      displayName: "Changes Detected"
      name: Changes
      condition: succeeded()
- stage: ...

使用上述管道yaml，始终运行“检测到的更改”脚本。我不确定我是否要按照正确的方式进行操作，因此不胜感激。

您认为采用删除文件和使用管道变量的方法会更好吗，例如：Skip stage with manual approval in Azure DevOps Pipelines (YAML)

更新：如果删除continueOnError: true，则整个管道将在该阶段之后停止，并拾取“未检测到更改”。我正在尝试使管道进入另一个阶段。

Answer 1

如果您可以将任务的输出捕获到变量中，则可以在下一个阶段利用custom conditional来选择执行。

steps:
- script: echo I did a thing
  condition: and(succeeded(), eq('${{ SkipSteps }}', false))

Answer 2

你实际上需要的是一个集合变量，然后在条件中使用它：

     - script: |
        terraform plan -input=false -no-color -out=plan.tfplan -detailed-exitcode
        # on changes detected, succeed; otherwise fail
        if [ $? -eq 2 ]; then 
          echo '##vso[task.setvariable variable=changedDetected]true'
        fi
      displayName: "Planning Terraform Changes"
      name: TerraformPlan
      condition: succeeded()
      continueOnError: true
      workingDirectory: "$(Build.SourcesDirectory)/terraform/$(ENVIRONMENT_NAME)"
      env:
        TF_IN_AUTOMATION: true
        ARM_CLIENT_ID: $(NONPROD_ARM_CLIENT_ID)
        ARM_CLIENT_SECRET: $(NONPROD_ARM_CLIENT_SECRET)
        ARM_SUBSCRIPTION_ID: $(NONPROD_ARM_SUBSCRIPTION_ID)
        ARM_TENANT_ID: $(NONPROD_ARM_TENANT_ID)
    - script: |
        echo "Nothing to do"
      displayName: "No changes detected"
      name: NoChanges
      condition: and(succeeded(), ne(variables['changedDetected'], 'true'))
    - script: |
        echo "Changes detected"
      displayName: "Changes Detected"
      name: Changes
      condition: and(succeeded(), eq(variables['changedDetected'], 'true'))

让ADO管道跳过Terraform计划中的步骤而无需更改
