如何使用Powershell更新VSTS发布作业代理程序池

Question

I am trying to update VSTS release definition agent pool using powershell. Able to get the agent id and release definition details.

Powershell :

$User = 'xxxx@software.com'
$PersonalAccessToken = 'xxxx'
$base64authinfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f  $User, $PersonalAccessToken)))
$vstsAccount = "software"
$resource = 'Enterprise'

#Get the Agent ID
$uri = "https://$vstsAccount.visualstudio.com/_apis/distributedtask/pools/"
$projects = Invoke-RestMethod -Method Get -ContentType application/json -Uri $uri -Headers @{Authorization=("Basic {0}" -f $base64authinfo)} | ConvertTo-Json
$projects = $projects | ConvertFrom-Json
Write-Host "Json Body :" $projects
$id = $projects.value | ? name -eq 'Hosted VS2017'
Write-Host "Agent Pool Id :" $id.id


#Get release definition details
$uri2 = "https://vsrm.dev.azure.com/$vstsAccount/$resource/_apis/release/definitions/860?api-version=5.0"
$projects2 = Invoke-RestMethod -Method Get -ContentType application/json -Uri $uri2 -Headers @{Authorization=("Basic {0}" -f $base64authinfo)} | ConvertTo-Json
$projects2 = $projects2 | ConvertFrom-Json
Write-Host "Json Body :" $projects2

                  }]

Now i want to update agent pool in release definition.

Reference : In VSTS, can I bulk change the agent queue?

Answer 1

You'll need to modify the object returned when you invoke $uri2 then use the PUT HTTP method to update the release definition in Azure DevOps.

Converting $projects2 to and from JSON is unnecessary, the objects can be manipulated directly. Remove | ConvertTo-Json | ConvertTo-Json from the end of the Invoke-RestMethod that sets $project2 and also the line $projects2 = $projects2 | ConvertFrom-Json $projects2 = $projects2 | ConvertFrom-Json .

To change the change the Agent Pool you'll need to update the queueId property of the relevant deploy phase in the relevant environment. If you had 1 environment with 1 deploy phase this would by done by

$projects2.environments[0].deployPhases[0].deploymentInput.queueId = $id.id

If you have multiple environments and/or deploy phases you'll need to change the array keys on those properties accordingly. Then convert the $projects2 object to JSON before sending the HTTP PUT request:

$body = $projects2 | ConvertTo-Json -Depth 10
$uri3 = "https://vsrm.dev.azure.com/$vstsAccount/$resource/_apis/release/definitions?api-version=5.0"
Invoke-RestMethod -Method Put -Uri $uri3 -Headers @{Authorization=("Basic {0}" -f $base64authinfo)} -Body $body -ContentType application/json
