Engine Allocation for Streams in Kubernetes Environment

I have hosted FME server in Kubernetes and trying to create a stream there.

I am not able to allocate any engine to my stream from the user interface and it shows this warning.

There are 2 links mentioned in the warning :

• https://community.safe.com/s/article/fme-server-on-docker-frequent-engine-scaling-and-j
• https://docs.safe.com/fme/html/FME_Server_Documentation/404-Redirect.htm

The second one gives 404 error.

The first one mentions about the allocation of engines to queues (nothing about streams).

 I also tried to check on the Engine Management page if there is any possibility to allocate engines to streams from there but no luck.

Job routing rules and Engine assignment rules have queues as one of the options but not streams.

There must be a way to allocate engines to streams in case of the Kubernetes deployment if I am not wrong.

Can someone please help me with the options.

Thanks in advance!
