Class CrdCompatibilityChecker

java.lang.Object

org.apache.flink.kubernetes.operator.api.validation.CrdCompatibilityChecker

public class CrdCompatibilityChecker
extends java.lang.Object

Utility for checking backward CRD compatibility.

The aim is to provide a very strict compatibility check logic initially that can be improved over time with compatible type changes if necessary by CRD updates

It performs the following checks:

• No property removed from any object
• No enum value removed from enums (changing enum to string is allowed)
• No type changes for fields
• No type changes for array/map items
• No change in extra properties of field schema definitions
