在Azure DevOps管道中，如何触发并等待另一个管道？

Question

在 Azure DevOps 中，我有两个管道：

• 管道A
• 管道B

现在，在 PipelineA 中，我想触发 PipelineB，并等待 PipelineB 完成。如果 PipelineB 成功，PipelineA 将继续，如果 PipelineB 失败，PipelineA 也将失败。

这是一个示例，其中一个管道作业将依赖于另一个管道作业。我想要相同的机制，但依赖于另一个管道的运行。

jobs:
- job: Debug
  steps:
  - script: echo hello from the Debug build
- job: Release
  dependsOn: Debug
  steps:
  - script: echo hello from the Release build

Answer 1

正如建议的那样，使用 DevOps API 是正确的选择。

这是一个 PowerShell 脚本，它调用另一个管道

param(
  [int]$pipelineId = 1234, # references https://dev.azure.com/a-comany/a-project/_build?definitionId=1234
  [string]$invokingPipelineName,
  [string]$invokingProject,
  [int]$invokingBuildId
)

# You need a token (which might be System.AccessToken), which requires the authorization "Build" -> "Read & execute".
$authToken = "1234abcdef0987..."

function Invoke-Pipeline
{
  $organization = "a-comany"
  $project = "a-project"
  $pipelineRunsUrl = "https://dev.azure.com/$organization/$project/_apis/pipelines/$pipelineId/runs?api-version=7.1"

  Write-Host "##[group] Invoking pipeline..."
  Write-Host "##[debug] PipelineId '$pipelineId' in $project"
  Write-Host "##[debug] Pipeline url: https://dev.azure.com/$organization/$project/_build?definitionId=$pipelineId"
  Write-Host "##[debug] Pipeline runs url: $pipelineRunsUrl"
  Write-Host "##[endgroup]"

  $base64AuthToken = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(":$authToken"))
  $headers = @{
    Authorization = "Basic $base64AuthToken"
    "cache-control" = "no-cache"
    "content-type" = "application/json"
  }
  $body = @{
    resources = @{
      repositories = @{
        self = @{
          refName = "refs/heads/main"
        }
      }
    }
    templateParameters = @{
      invokingPipelineName = $invokingPipelineName
      invokingProject = $invokingProject
      invokingBuildId = $invokingBuildId
    }
  } | ConvertTo-Json -Depth 3 -Compress

  $createRunResponseJson = Invoke-RestMethod -Uri $pipelineRunsUrl -Method Post -Headers $headers -Body $body -ErrorAction Stop
  $pipelineRunUrl = $createRunResponseJson.url
  $runId = $createRunResponseJson.id

  Write-Host "Started pipeline, runId: $runId"
  Write-Host "##[group] Pipeline run web url: $( $createRunResponseJson._links.web.href )"
  Write-Host "##[debug] $createRunResponseJson"
  Write-Host "##[endgroup]"

  while ($true)
  {
    $getStatusResponseJson = Invoke-RestMethod -Uri $pipelineRunUrl -Headers $headers -ErrorAction Stop
    $pipelineRunUrl = $getStatusResponseJson.url

    Write-Host "##[group] Pipeline state: $( $getStatusResponseJson.state ) ($( Get-Date -Format "HH:mm:ss" ) GMT)"
    Write-Host "##[debug] Run web url: $( $getStatusResponseJson._links.web.href )"
    Write-Host "##[debug] $getStatusResponseJson"
    Write-Host "##[endgroup]"

    if ($getStatusResponseJson.state -ne "inProgress")
    {
      break
    }

    Start-Sleep -Seconds 5
  }
  Write-Host "result at: https://dev.azure.com/$organization/$project/_build/results?buildId=$runId"

  if ($getStatusResponseJson.result -ne "succeeded")
  {
    Write-Error "Invoking did not succeed" -ErrorAction Stop
  }
  Write-Host "Invoking finished successfully"
}

Invoke-Pipeline

在Azure DevOps管道中，可以像这样执行：

- task: PowerShell@2
  displayName: Invoke pipeline
  inputs:
    filePath: invoker.ps1
    arguments: >
      -invokingPipelineName "$(Build.DefinitionName)"
      -invokingProject "$(System.TeamProject)"
      -invokingBuildId "$(Build.BuildId)"

调用的管道具有参数，以便在管道运行时显示调用者/“返回方式”：

parameters:
  - name: invokingPipelineName
    type: string
    default: ' '
  - name: invokingProject
    type: string
    default: ' '
  - name: invokingBuildId
    type: number
    default: 0

steps:
  - script: |
      echo Invoking pipeline name: ${{ parameters.invokingPipelineName }}
      echo Invoking pipeline run: https://dev.azure.com/a-company/${{ parameters.invokingProject }}/_build/results?buildId=${{ parameters.invokingBuildId }}
    displayName: Print invoker (if given)
    condition: ne('${{ parameters.invokingPipelineName }}', ' ')
