如何在Azure Devops管道中使用PowerShell根据条件触发代理作业 [英] How to trigger Agent Job As per condition using PowerShell in Azure Devops Pipeline

问题描述

我有一个PowerShell，如下所示:

I have a PowerShell as below:

echo "Hello-World"
$MyVariable = "Proceed"
echo $MyVariable

我想做什么:

如果 MyVariable 仅是"继续"，则必须运行Agent Job2

If the MyVariable is "Proceed" Only and only then Agent Job2 Should run

我已使用PowerShell任务并将给定变量名称用作MyVariableOutput

I have used PowerShell task and Given Variable name as MyVariableOutput

我已在Agent Job2级别完成以下配置

I have done below configuration at Agent Job2 level

请让我知道我该如何处理这些条件:

Can you please let me know how can I put these condition:

仅当Agent Job1上的Powershell脚本生成 Proceed 作为 MyVariable 的值时 代理Job2将运行.

Only If the Powershell Script at Agent Job1 Produce the Proceed as the value of MyVariable Agent Job2 will run.

注意:Agent Job1和Agent Job2是同一发布管道的一部分

推荐答案

如果您希望使用 GUI 配置管道，则必须运行脚本以将 MyVariable 添加为通过调用此定义的变量将不会转移到下一个代理作业. agent job1和agent job2彼此独立.

If you prefer to configure your pipeline with GUI, you must run script to add the MyVariable as Variables instead of a temporary variable by calling this api. Because after the agent job1 finished, the variable you just defined with $MyVariable = "Proceed" will not transfer to the next agent job. The agent job1 and agent job2 are independent with each other.

在座席工作1中:

配置2个Powershell任务.

Configure 2 powershell tasks.

(1)第一个用于定义带有值的变量并将其设置为输出变量:

(1) The first one is used to define a variable with value and set it as output variable:

echo "Hello-World"
echo "##vso[task.setvariable variable=MyVariable;isOutput=true]Proceed"
echo $MyVariable

不要忘记在此任务中指定其reference名称 MyVariableOutput .

Do not forget specify its reference name MyVariableOutput in this task.

(2)第二个作业用于将此output variable添加到Variables中，然后agent job2可以访问它:

(2) The second job is used to add this output variable into Variables, then the agent job2 could access it:

$connectionToken="{token}"
$urlget = "https://vsrm.dev.azure.com/{org}/{project}/_apis/release/releases/$(Release.ReleaseId)?api-version=5.1"
$base64AuthInfo = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($connectionToken)"))
$getdef = Invoke-RestMethod -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)} -Method GET -ContentType application/json -Uri $urlget 
##Write-Host Pipeline = $($getdef | ConvertTo-Json -Depth 100)
$MyVariable=@"
    {
      "value": "$(MyVariableOutput.MyVariable)"
    }
"@
$getdef.variables | add-member -Name "MyVariable" -value (Convertfrom-Json $MyVariable) -MemberType NoteProperty -Force -PassThru

$getdef = $getdef | ConvertTo-Json -Depth 100
$getdef | clip
$urlput = "https://vsrm.dev.azure.com/{org}/{project}/_apis/release/releases/$(Release.ReleaseId)?api-version=5.1"
$putdef = Invoke-RestMethod -Uri $urlput -Method PUT -Body $getdef -ContentType "application/json" -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)}

上面的脚本将创建一个变量MyVariable，其值是Proceed.

The above script will create a variable MyVariable which its value is Proceed.

在agent job2中，配置条件，如下所示:

In agent job2, configure the condition as the shown below:

eq(variables['MyVariable'],'Proceed')

您可以看到代理job2可以成功运行，因为它已检测到MyVariable的值为Proceed.

You can see the agent job2 can be run successfully since it has detect the value of MyVariable is Proceed.
