Access variables of parallel steps by continuous polling

spannala · 30 November 2022 22:33

Hi,
I am working on a scenario where I need to cancel the release when a manual intervention step left
unattending for sometime after the MI step started.
I have a custom script running in parallel with the Manual intervention step. This step consists of a timer and continuously polls using
get_octopusvariable(‘Octopus.Step[step name].Status.Code’).
I am having issue in getting the value of the above code.
how can I access variables from steps which are running in parallel.

Hi @spannala
Welcome to the Octopus forum!

I believe the following PS script can help with your query:

github.com

OctopusDeploy/OctopusDeploy-Api/blob/master/REST/PowerShell/Deployments/CancelLongRunningTasks.ps1

$OctopusURL = $OctopusParameters["Global.Base.Url"]
$APIKey = $OctopusParameters["Global.Api.Key"]
$CurrentSpaceId = $OctopusParameters["Octopus.Space.Id"]
$MaxRunTime = 15

$header = @{ "X-Octopus-ApiKey" = $APIKey }

Write-Host "Getting list of all spaces"
$spaceList = (Invoke-RestMethod "$OctopusUrl/api/Spaces?skip=0&take=100000" -Headers $header)
$cancelledTask = $false
$cancelledTaskList = ""

foreach ($space in $spaceList.Items)
{
    $spaceId = $space.Id
    if ($spaceId -ne $CurrentSpaceId)
    {
        Write-Host "Checking $spaceId for running tasks (looking for executing tasks only)"
        $taskList = (Invoke-RestMethod"$OctopusUrl/api/tasks?skip=0&states=Executing&spaces=$spaceId&take=100000" -Headers $header)
        $taskCount = $taskList.TotalResults

The idea is to scan and find long running tasks and identify and cancel them. You can set some parameters such as max run time to fine tune how long a running task is allowed to go before cancelling.

You can also just mask out the cancel command and see what returns and manipulate the data as needed.

We have a list of system variables such as the one you mentioned to get the value of steps and processes:

If you need help with any of the above just let us know and we can jump in.

Kind regards,
Paraic

Thank you.
I used an API call to check the interruptions. It worked for me.
“{uri}/api/{spaces}/interruptions”
