Creating a host Key using Bicep

Question

Creating a host Key using Bicep

Graham Allwood 306

Hi,

Does anyone know how to create a Host key using Bicep (arm)? I ultimately want to set up an API Management instance to use my function app as a backend and I need to create a new host key in the functionapp for APIM to use.

Currently using Bicep as the language to drive my infrastructure as code :)

Thanks

Graham

Hi @Graham Allwood - I would stay in ARM for now and look to leverage the automation work that is done here: Azure API Management DevOps Resource Kit

FYI that the APIM team is currently reviewing the adoption of Bicep (or migration to) for this DevOps Kit. As for generating the host keys for your Functions, there are REST endpoints that can be invoked at the respective abstraction in your ARM templates, please review: https://github.com/Azure/azure-functions-host/wiki/Key-management-API

@Graham Allwood It looks like Bicep has a listKeys() function that you can use: https://github.com/Azure/bicep/blob/0d3b8a624e2ef4769f64b4bd263f649d08e85562/docs/examples/201/aci-wordpress/main.bicep#L69

Thanks for the reply @Mike Urnun .

I managed to create the function app key in my Bicep file, but intellisense isn't happy. Works ok though.

resource functionApp 'Microsoft.Web/sites@2020-06-01' = {  
  name: functionAppName_var  
  location: location  
  kind: 'functionapp'  
  properties: {  
    serverFarmId: hostingPlan.id  
    siteConfig: {  
      appSettings: [  
...  
      ]  
    }  
  }  
}  
  
resource functionKey 'Microsoft.Web/sites/host/functionkeys@2018-11-01' = if (apiManagementName != null) {  
  name: '${functionApp.name}/default/apim-${apiManagementName}'  
  properties: {  
    name: 'apim-${apiManagementName}'  
  }  
}  
  
output functionKeyValue string = functionKey.properties.value
