Code change:
Is this a BUG REPORT or FEATURE REQUEST?: What happened: Azure will not update the DNS label of the public IP, when update the service only changing the annotation of the DNS label from empty. annotations: -annotations: "to-update" What you expected to happen: It should update the dns label of the assigned public IP How to reproduce it (as minimally and precisely as possible): It probably caused when applying function 'getPublicIPAddress' in This function returns a bool 'existsPip' to judge the public ip existence. When only the annotations changed, the existsPip still returns true. Then, the reference in line 553 and line 446 step into this bug. pip, existsPip, err := az.getPublicIPAddress(pipResourceGroup, pipName) if err != nil { return false, err } if !existsPip { return true, nil } Firstly, in line 554, it will make function 'isFrontendIPChanged' return false, and then will not run 'ensurePublicIP' in line 691. Secondly, even if 'ensurePublicIP' in line 691 runs, it will detect the public ip exists and make no update to the DNS label in line 446_. Environment: Kubernetes version (use ): Cloud provider or hardware configuration: Azure
