Set environment variable override for AuthorizationLevel.Function key
When running within the Azure Functions Runtime inside of a Docker container, we can't use AuthorizationLevel.Function as there is no way to retrieve the key from the runtime. It'd be great if we could directly set a function key in our compose.yml as an environment variable. For deployment, we just leave the environment variable blank and the App Service can set the keys.
We do have this set up for Kubernetes deployments, but there is not yet anything for standard Docker. This is a valid request, but we don’t have a timeline attached to it.
Is it apply to AppService, too? I'm using Function Proxy and want to pass `function key` in Proxies.json, but currently there are no way to get key from environment variable.
