ARM Deployment: Get Azure Function API Key

Question

As part of a Stream Analytics deployment solution I want to retrieve the API key for a Azure Function App in an ARM template via e.g. the listkeys() function. Is there a way to retrieve this key via an ARM template respectively during an ARM deployment and if yes, how?

Thanks

Answer 1

This question has already been answered here:

• listKeys for Azure function app
• Get Function & Host Keys of Azure Function In Powershell

What is important in this context is to set the 'Minimum TLS Version' to '1.0' before deploying the job. Otherwise you will get failures when testing the connection health.

The new Key Management API of Azure Functions has gone live. Its possible via the following ARM Script. Also check this Github issue

"variables": {
    "functionAppId": "[concat(parameters('functionAppResourceGroup'),'/providers/Microsoft.Web/sites/', parameters('functionAppName'))]"
},
"resources": [
    {
        "type": "Microsoft.KeyVault/vaults/secrets",
        "name": "[concat(parameters('keyVaultName'),'/', parameters('functionAppName'))]",
        "apiVersion": "2015-06-01",
        "properties": {
        "contentType": "text/plain",
        "value": "[listkeys(concat(variables('functionAppId'), '/host/default/'),'2016-08-01').functionKeys.default]"
        },
        "dependsOn": []
    }
]

Have anyone succeded in useing this in the same template as the function app is created? I am having issues with host/default not existing. – Miscarriage

This is not possible since the function keys are generated when a Http triggered function is deployed inside the function app. – Baecher
