Output newly created function app key using Bicep

I have a bicep template that creates a function app in a dedicated module. I would like out the function app key from the module. Anyone know how I can get the function key?

I can't find it in the list of properties:

Solution

  • If you would like to retrieve the default host key, you can use the listkeys function:

    param functionAppName string

resource functionApp 'Microsoft.Web/sites@2022-09-01' existing = {
  name: functionAppName
}

resource functionAppHost 'Microsoft.Web/sites/host@2022-09-01' existing = {
  name: 'default'
  parent: functionApp
}

// Default host key
output defaultHostKey string = functionAppHost.listKeys().functionKeys.default

// Master key
output masterKey string = functionAppHost.listKeys().masterKey

// Addtionally grab the system keys
output systemKeys object = functionAppHost.listKeys().systemKeys
