- Remove string decode logic. It's not really helping to find the conflict ports, and it's expensive to do encoding/decoding - Not to parse the container ports information in predicate meta, use straight []*v1.ContainerPort - Use better data structure to search port conflict based on ip addresses - Collect scattered source code into common place
