The PolarDB-X Operator supports two networking modes: Container network and Host Network. When creating a PolarDB-X instance, if the Host Network is used, the pods directly utilize random ports on the host, which may conflict with other processes' ports on the host, causing the service to fail to start.

  1. If the process occupying the port on the host can be stopped or its port changed, simply stop the process or change the port, and then allow the pod to be pulled up again.
  2. If the port cannot be changed, directly recreate the PolarDB-X instance. This will generate new random ports, which are unlikely to encounter port conflicts.
