在 AzureDevOps 管道中将仅在运行时已知的输出变量从 job1 传递到模板 job2

Question

我有一个带有作业模板的天蓝色 DevOps 管道。

我需要将前一个作业中的变量传递到作业模板中。

在作业中，您可以导出变量：

echo "##vso[task.setvariable variable=runtimevar1]test"

在各个作业中，您可以设置一个标志，并将其导入到下一个作业的变量中：

    variables:
      var1: $[ dependencies.job1.outputs['setvars.runtimevar2'] ]

echo "##vso[task.setvariable variable=runtimevar2;isOutput=true]test2"

但是，当使用模板时，这不起作用，因为您无法将变量块传递给模板

当 job2 是模板时，是否有一种简单的方法将输出变量（仅在运行时已知）从 job1 传递到 job2？

Answer 1

不能通过参数传递输出变量。参数需要提前给定，不能是运行时产生的。

但是您可以使用

$[ dependencies.job1.outputs['setvars.runtimevar2'] ]

在模板作业中定义变量，如示例代码中所示，然后使用它

echo remote var $(remotevar)

而不是

${{ variables.remotevar }}

我认为您遵循了正确的方法，但是使用变量时出现了一些错误

这是您的示例代码，进行了一些细微的修改。

main.yml

stages:
- stage: stage1
  jobs:
  - job: job1
    steps:
    # set a variable
    - script: |
        echo "##vso[task.setvariable variable=runtimevar1]test"
        echo "##vso[task.setvariable variable=runtimevar2;isoutput=true]test2"
      name: setvars
      displayName: 'set vars'

    - script: |
        echo runtimevar1: $(runtimevar1)
        echo runtimevar2: $(setvars.runtimevar2)
      displayName: echovars

  - job: job2
    dependsOn: job1
    variables:
      var2: $[ dependencies.job1.outputs['setvars.runtimevar2'] ]
    steps:
    - script: |
        echo "var2: $(var2)"
      displayName: echovars

  # this does not work
  - template: ./test-job.yaml
    parameters:
      var1: "hello world"

test-job.yml

parameters:
- name: var1
  type: string

jobs:
- job: testjob
  displayName: testjob-template1
  dependsOn: job1
  variables:
  - name: remotevar
    value: $[ dependencies.job1.outputs['setvars.runtimevar2'] ]

  steps:
  # Get the Azure credentials for this environment
  - script: |
      echo param1 var1 ${{ parameters.var1 }}
      echo remote var $(remotevar)
    displayName: 'echo vars'
