How to Submit a UDF in a Kubernetes Cluster?
I'm trying to submit a user-defined function (UDF) in a Kubernetes cluster, specifically on Google Kubernetes Engine (GKE), but the documentation I found only mentions localhost and Docker. I'm not sure which pod I should forward to among the ones listed in my cluster. Can you guide me on how to launch a pod for UDFs and how to connect it with the rest of the services?

I've figured out that I need to create a custom pod/docker image that runs a server with my UDFs. Then I can link any SQL to that pod/server to use the UDFs I've defined. I don't have documentation for this process, but I will create a Docker image, a Kubernetes deployment, and a service for other pods to connect to the UDF server. I'll make sure the server can connect to the RisingWave cluster and share the steps and example YAML files once I've completed the setup.
