I’m building an Azure DevOps pipeline, and wanted to separate out parameter input into it’s own file which may be re-used across multiple different task types. I investigated a method of declaring parameters in JSON, and then ingesting them in a PowerShell script and using it to populate PowerShell variables.
For the time being, I’ve simplified my code to just use a direct PowerShell dot-sourced file, but want to keep this code snippet here for future reference.
JSON File
{ "subscriptionid": "3d22393a", "resourceGroupName": "test-rg", "azureLocation": "EastUS2", "automationAccountName": "test-auto", "dscConfigurationname": "dsc_baseconfig", "dscConfigurationFile": "dsc_baseconfig.ps1", "keyvaultName": "kv123" } |
PowerShell
# Import parameters from common JSON for reuse # This file cannot have comments in it! param( [string]$paramFile = '.\dsc_parameters.json' ) # For each object in the JSON, create a powershell variable $params = Get-Content $paramFile | ConvertFrom-Json $params.PSObject.Properties | ForEach-Object { New-Variable -Name $_.Name -Value $_.Value -Force } |
