How can we pass topic and subscription name from yaml in azure function - java

Question

I want to fetch subscriptionName value from deployment.yaml , config map settings. How can I get the value from there.

@FunctionName("TestHandler")
public void Handler(
@ServiceBusTopicTrigger(
name = "ServiceBus",
topicName = "topicname",
connection = "ServiceBusConnectionString",
subscriptionName = "subscriptionName")
String message,
final ExecutionContext context) {}

I tried passing value of subscriptionName as subscriptionName = "%MY_SUBSCRIPTION_CONFIG%" . But that doesn't take value from yaml

@Gaurav Mantri could you please suggest

To read from app settings (or environment variables) using %<key>% should do the trick. In K8s, you would have to configure all key-value pairs in a ConfigMap as container environment variables for them to be picked up.
