Configuring Pipeline dependencies in Azure Pipelines

Question

I have 2 Azure Pipelines, deploy and test. As their names imply one is used for deploying a product and the other is used for testing. When a developer wants to run their own tests on the existing deployment they trigger test. When a deployment is required they trigger deploy. If the test pipeline is in execution when the deploy pipeline is triggered I want the deploy to wait till the test has finished executing.

Is there a way to configure this dependency within the pipeline.yaml themselves, or a workaround to achieve the mentioned requirement

Hi @JAbeywrdana Is there any update about this ticket? Feel free to let me know if the suggestion could give you some help. Just a remind of this. — Kevin Lu-MSFT
Hi @Kevin Lu-MSFT, Sorry for the late response, I am in the process of trying out your solution, I actually have to write the querying process in bash instead of powershell which is why there maybe a small delay. But I tried executing a few curl commands to see the status and it should work. I will provide a confirmation on this ASAP — JAbeywrdana

Is there a way to configure this dependency within the pipeline.yaml themselves, or a workaround to achieve the mentioned requirement

Here are two methods could meet your requirement:

1.You could add the Environment in your Yaml Pipeline. Add you could add Invoke Rest API check in the environment. Rest API: Latest - Get

In Yaml Pipeline, you could call this environment.

Example:

stages:
- stage: deploy
  jobs:
  - deployment: DeployWeb
    displayName: deploy Web App
    pool:
      vmImage: 'Ubuntu-latest'
    environment: 'EnvironmentName'
    strategy:
      runOnce:
        deploy:
          steps:
          ...

When you run the pipeline, the environment will check the latest build status of the test Pipeline. If the build has completed , it will run the deploy pipeline.

Result:

2.You could directly add a Powershell task in the Deploy task to check the status of the Test Pipeline.

$token = "PAT"

$url="https://dev.azure.com/{OrganizationName}/{ProjectName}/_apis/build/definitions/{DefinitionID}?includeLatestBuilds=true&api-version=5.1"


$token = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($token)"))


$response = Invoke-RestMethod -Uri $url -Headers @{Authorization = "Basic $token"} -Method Get -ContentType application/json



$buildid = $response.latestBuild.id
echo $buildid


$success = $false

do{
    try{
    $Buildurl2 = "https://dev.azure.com/{OrganizationName}/{ProjectName}/_apis/build/builds/$($buildid)?api-version=5.0"


    $Buildinfo2 = Invoke-RestMethod -Method Get -ContentType application/json -Uri $Buildurl2 -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)}

    $BuildStatus= $Buildinfo2.status 
    $result = $Buildinfo2.result
    echo $result
    echo $BuildStatus


 
   
        if($BuildStatus -eq "completed"  ) {            

            write-output "No Running Pipeline, starting Next Pipeline"
            $success = $true 
                       
      } else {   
            Write-output "Pipeline Build In Progress, Waiting for it to finish!"  
            Write-output "Next attempt in 30 seconds"
            Start-sleep -Seconds 30         

            }
    
      
    }
    catch{
        Write-output "catch - Next attempt in 30 seconds"
        write-output "1"
        Start-sleep -Seconds 30
      # Put the start-sleep in the catch statemtnt so we
      # don't sleep if the condition is true and waste time
    }
    
    $count++
    
}until($count -eq 2000 -or $success -eq $true )
if ($result -ne "succeeded" )
{
   echo "##vso[task.logissue type=error]Something went very wrong."
}

if(-not($success)){exit}
