Azure Functions: CosmosDBTrigger connection string storage

Question

I asked yesterday where to store the connection string for a CosmosDBTrigger. It worked great until I had to push it up to Azure. Now the function isn't working at all. It works locally just fine though. There is no difference between codebases so the only thing I can think of is the connection string isn't be pulled from local.settings.json when on Azure. I mean, it wouldn't surprise me if that was the case since the file has the word local in it.

I tried putting the contents in the host.json , but that didn't work either.

How do you specify the connection string when your Function is running on Azure?

Answer 1

local.settings.json is not used in Azure. Instead, settings are taken from App Service Settings .

For your yesterday's example, go to Function App's Application settings tab and add a value with key DbConnString there.

If you are using func CLI, you can publish settings from local.settings.json file to Azure Application settings by running

func azure functionapp public <App> --publish-local-settings

Answer 2

You need to put it in the Application Settings for the function app. These can be setup using the Azure Portal or deployed as part of the ARM template I believe.
