Function apps don't handle CI/CD

[MarkAtAgilliance]

Just a note that function apps do not parameterize their key values in the ARM template so hard to deploy to multiple environments. Not sure what the plan is but today, this makes a mess of CICD because there is no easy way to override the functionAppUrl or the functionKey values in the ARM template. Maybe add a caution box in the doc above until this is fixed.

@MarkAtAgilliance Thanks for your feedback! We will investigate and update as appropriate.

@MarkAtAgilliance There were a few changes done recently on Function Apps because of which parameterizing key values in ARM templates was affected. To read more about this, please refer this article. The product team is working on rectifying it and it should be done soon.

There's a workaround however to get you unblocked for now. Here is a sample to inject a default functions key in a key vault secret (Ref :#3994) :

"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": []
}
]

Hope this helps.

I will now proceed to close this issue. Please feel free still to comment and tag me if you have any queries or ideally provide your feedback on a doc pertaining to Function apps.

just to follow up, I eventually did a similar thing but used powershell script instead. Details in the solution here https://stackoverflow.com/questions/57192228/using-function-app-connector-in-adf-how-to-override-parameters-in-ci-cd
I will also investigate if the custom parameters approach can work around this since we need it for another reason (>256 params).
