在 Azure 管道中动态创建变量

Question

我正在尝试在 azure piplelines 阶段生成发行说明并将说明推送到 azure 服务总线。

如何在 bash 脚本中公开变量，然后在同一阶段的后续作业中使用它？

我正在使用 bash 任务来执行 git 命令并尝试将其导出为我想在以下作业中使用的环境变量。

  - stage: PubtoAzureServiceBus
    variables:
      COMMIT_MSG: "alsdkfgjdsfgjfd"
    jobs:
      - job: gitlog
        steps:
          - task: Bash@3
            inputs:
              targetType: 'inline'
              script: |
                # Write your commands here
                
                export COMMIT_MSG=$(git log -1 --pretty=format:"Author: %aN%n%nCommit: %H%n%nNotes:%n%n%B")
                env | grep C
      - job:
        pool: server
        dependsOn: gitlog
        steps:
          - task: PublishToAzureServiceBus@1
            inputs:
              azureSubscription: 'Slack Release Notifications'
              messageBody: |
                {
                  "channel":"XXXXXXXXXX",
                  "username":"bot",
                  "iconEmoji":"",
                  "text":":airhorn: release :airhorn: \n`$(COMMIT_MSG)`"
                }
              signPayload: false
              waitForCompletion: false

您需要使用logging syntax and output variables，如下所示：

trigger: none

pool:
  vmImage: 'ubuntu-latest'

stages:
- stage: A
  jobs:
  - job: A1
    steps:
     - bash: echo "##vso[task.setvariable variable=shouldrun;isOutput=true]true"
     # or on Windows:
     # - script: echo ##vso[task.setvariable variable=shouldrun;isOutput=true]true
       name: printvar

- stage: B
  dependsOn: A
  jobs:
  - job: B1
    condition: in(stageDependencies.A.A1.result, 'Succeeded', 'SucceededWithIssues', 'Skipped')
    steps:
    - script: echo hello from Job B1
  - job: B2
    variables:
      varFromA: $[ stageDependencies.A.A1.outputs['printvar.shouldrun'] ]
    steps:
    - script: echo $(varFromA) # this step uses the mapped-in variable

请查看here 以查看文档。

所以你需要更换

                export COMMIT_MSG=$(git log -1 --pretty=format:"Author: %aN%n%nCommit: %H%n%nNotes:%n%n%B")

isOutput=true 的智能日志记录命令

然后把它映射到这里

jobs:
- job: A
  steps:
  - bash: |
       echo "##vso[task.setvariable variable=shouldrun;isOutput=true]true"
    name: ProduceVar  # because we're going to depend on it, we need to name the step
- job: B
  dependsOn: A
  variables:
    # map the output variable from A into this job
    varFromA: $[ dependencies.A.outputs['printvar.shouldrun']
  steps:
  - script: echo $(varFromA) # this step uses the mapped-in variable

因为您想在作业之间共享变量（而不是第一个示例中显示的阶段）。
