Subscription feature in K8S. about iot-edge-opc-plc HOT 4 CLOSED

@chunchiehdev, the opc plc simulation opc ua server is designed to act like a standalone containerized application. It is not designed to run in a k8s cluster as a distributed architecture. If you spin multiple instances just do this using separate deployments with replica set always to 1. Increasing replica setting to more than 1 will just end up in un-predictable behavior of the multiple instances of the opc plc. They are completely unaware about any peers deployed in the same cluster and act as independent standalone applications.

Can you please elaborate your use-case and explain the reason you want/need to run multiple replicas?
At first sight, this doesn't look like a supported scenario.

Thank you for your response.

By running multiple replicas, I aim to ensure that the OPC PLC service remains available even if one or more Pods fail.
Also distribute the client requests across different Pods to enhance performance.

Are there any best practices or solutions for synchronizing node values across multiple replicas in such a setup?

Thank you for the detailed explanation. Now I understand.
