json - Trying to make if/else powershell for ARM template -

i have powershell script arm template deploy resources azure, more ase v2.

my arm template has condition in stating:

"sv-ase-version": "v2",      "sv-asp-template-filenamehash": {       "v1": "[concat(variables('sv-baseuri'),concat('/azuredeploy-asp.v1.json',parameters('_artifactslocationsastoken')))]",       "v2": "[concat(variables('sv-baseuri'),concat('/azuredeploy-asp.json',parameters('_artifactslocationsastoken')))]"     }, 

what have right in powershell:

param(      [string] $templatefile = 'azuredeploy-dev.json',     [string] $templateparametersfile = 'azuredeploy-dev.parameters.json',  )  $templatefile = [system.io.path]::getfullpath([system.io.path]::combine($psscriptroot, $templatefile)) $templateparametersfile = [system.io.path]::getfullpath([system.io.path]::combine($psscriptroot, $templateparametersfile)) 

what wanna add in powershell is:

param(      [string] $templatefile = 'azuredeploy-dev.json',     [string] $templateparametersfile = 'azuredeploy-dev.parameters.json',     [string] $templatefilev2 = 'azuredeploy.json',     [string] $templateparametersfilev2 = 'azuredeploy.parameters.json',  )  #checking if correct way  if ("sv-ase-version" -eq "v1") {      $templatefile = [system.io.path]::getfullpath([system.io.path]::combine($psscriptroot, $templatefile))     $templateparametersfile = [system.io.path]::getfullpath([system.io.path]::combine($psscriptroot, $templateparametersfile))  } else {      $templatefilev2 = [system.io.path]::getfullpath([system.io.path]::combine($psscriptroot, $templatefilev2))     $templateparametersfilev2 = [system.io.path]::getfullpath([system.io.path]::combine($psscriptroot, $templateparametersfilev2))  } 

my intention: make switch in json file, without needing change things in powershell.

would work? how approach differently?

thanks.

the easiest way use parameter in template, call deploymentprefix:

"deploymentprefix": {     "type": "string",     "defaultvalue": "dev",     "allowedvalues": [         "dev",         "prod"     ],     "metadata": {         "description": "resources created prefixed this."     } }, 

and based on value of parameter decide deploy in template:

"variables": {     "template-dev": "someurl",     "template-prod": "someotherurl",     "template-url": "[concat('template-', parameters('deploymentprefix))]"     ... } 

and in powershell use new-azurermresourcegroupdeployment , pass (dev or prod) parameter , template figure out use template-url variable.
