Azure DevOps YAML Pipeline 基于变量设置部署环境

Question

我正在尝试编写一个 Azure DevOps YAML 管道，我在前一个作业中动态设置部署环境。这是我正在尝试做的一个概念性示例：

pool:
  vmImage: 'ubuntu-latest'

stages:
- stage: SetVariable
  jobs:
  - job: SetVariableJob
    steps:
    - script: |
        echo "##vso[task.setvariable variable=environmentName;isOutput=true]TestEnvironmentName"
      name: setvarStep

- stage: Deploy
  dependsOn: SetVariable
  variables:
    environmentName: $[ dependencies.SetVariable.outputs['SetVariableJob.setvarStep.environmentName'] ]
  jobs:
  - deployment: DeployWeb
    environment: $(environmentName)
    strategy:
      runOnce:
        deploy:
          steps:
          - script: echo Hello, $(environmentName)!

出了点问题，因为

echo Hello, $(environmentName)!

只是输出：

Hello, !

Answer 1

如果你想跨阶段共享变量。你可以用

stageDependencies.stageName.jobName.outputs['stepName.variableName']

因此您可以如下修改 yaml 文件：

- stage: Deploy
  dependsOn: SetVariable
  variables:
    environmentName: $[ stageDependencies.SetVariable.SetVariableJob.outputs['setvarStep.environmentName'] ]
  jobs:
  - deployment: DeployWeb
    environment: $(environmentName)
    strategy:
      runOnce:
        deploy:
          steps:
          - script: echo Hello, $(environmentName)!
