What-If and conditional deployment

[rvvincelli]

Describe the noise

Resource type (i.e. Microsoft.Storage/storageAccounts): any

apiVersion: n/a

Client (PowerShell, Azure CLI, or API): PowerShell

Relevant ARM Template code (we only need the resource object for the above resourceType and apiVersion, but if it's easier you can include the entire template:

...
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
"parameters": {
...
    "reDeployETLInfra": {
      "type": "int",
      "defaultValue":1,
      "metadata": {
        "description": "Toggle (1 or 0) to determine if the ETL infra (ADF, databricks) needs to be redeployed"
      }
    }
...
"resources": [
...
{
      "condition": "[equals(parameters('reDeployETLInfra'),1)]",
      "apiVersion": "2019-10-01",
      "name": "datafactorydeployment",
      "type": "Microsoft.Resources/deployments",
...

Expected response (i.e. "I expected no noise since the template has not been modified since the resources were deployed): the default parameter value is 1 and it is not overridden, so I expect to see updation information for this ADF instance too.

Current (noisy) response (either include a screenshot of the what-if output, or copy/paste the text): n/a

Additional context: the command we use is New-AzResourceGroupDeployment -ResourceGroupName ??? -TemplateFile azuredeploy_world.json -TemplateParameterFile azuredeploy_world_params.json -Whatif -WhatIfResultFormat FullResourcePayloads

Not sure if this is noise, expected behavior or just unsupported. Apologies in advanced if we missed any information in this sense, please gently point to the relevant docs.

Thank you,

On the same lines, it feels like resources showing a dependsOn are ignored too (please point us to the relevant issues). Thanks,

Can you clarify what were you expecting to see? Can you share the output of the what-if response and what in the response looks incorrect?

resources with a dependsOn property should not be ignored. We have #157 related to nested deployments. Could it be related to that?

See the reDeployETLInfra param and the condition: if the param is true the condition is true too and the deployment shall launch. This works in vivo but whatif seems to ignore this altogether, skipping the resource regardless of the condition value.

Thanks for linking to it, it might well be! I cannot promise to look into this right now but that's a good starting point.
