How can i pass a variable between tasks in Azure Devops/VSTS

问题

For Task 1 I have a CLI task which simply gets the subnet name and subnet ref as below

$subnetname1 = az network vnet subnet list --resource-group vnetrg01 --vnet-name vnet01 --query "[].name" -o tsv $subnetref1 = az network vnet subnet list --resource-group vnetrg01 --vnet-name vnet01 --query "[].id" -o tsv

For task 2 I want to deploy an arm template which will use parameters from the pipleine variables in Azure Devops So for example the result of $subnetref1 in Task 1 above needs to populate the pipleline variable for subnetref (which is setup as a variable in the pipleine) which will then be passed to the arm template override parameters

cant seem to get this working

回答1:

You can do it with Powershell command,

In the first PowerShell task set the variable as environment variable:

$subnetname1 =  az network vnet subnet list --resource-group vnetrg01 --vnet-name vnet01 --query "[].name" -o tsv 
Write-Host $subnetname1
Write-Host ("##vso[task.setvariable variable=subnetname1;]$subnetname1")

In the second task read the variable in this way:

$subnetname1 =  $env:subnetname1
Write-Host $subnetname1
