Connect Appservice to application insights in a different resource group

[sreejaptfa]

How do we deploy appservice but connect the appservice to application insights in a different resource group?

Hi @sreejaptfa Here are the docs for the Application insights.

https://docs.microsoft.com/en-us/azure/azure-monitor/app/azure-web-apps?tabs=net#automate-the-creation-of-an-application-insights-resource-and-link-to-your-newly-created-app-service

As you can see you can pass in the reference to the AppInsights via the AppSettings on the site.

There are a few different syntaxes that you could use.

example 1 - very similar to ARM/json style, just in bicep.

var appInsightsName = 'myAppInsights'
var appInsightsID = resourceId('otherRG','Microsoft.insights/components/', appInsightsName)

...

    siteConfig: {
      appSettings: [
        {
          name: 'APPINSIGHTS_INSTRUMENTATIONKEY'
          value: reference(AppInsightsID, '2015-05-01').InstrumentationKey
        }
        {
          name: 'APPLICATIONINSIGHTS_CONNECTION_STRING'
          value: reference(AppInsightsID, '2015-05-01').ConnectionString
        }

example 2 - the bicep way 💪 using 'existing'.

var appInsightsName = 'myAppInsights'
var otherRG = 'theOtherResourceGroupName'

resource appInsights 'Microsoft.Insights/components@2020-02-02-preview' existing = {
  name: appInsightsName
  scope: resourceGroup(otherRG)
}

...

    siteConfig: {
      appSettings: [
        {
          name: 'APPINSIGHTS_INSTRUMENTATIONKEY'
          value: appInsights.properties.InstrumentationKey
        }
        {
          name: 'APPLICATIONINSIGHTS_CONNECTION_STRING'
          value: appInsights.properties.ConnectionString
        }
