@char-1ee Please fix the errors reported by the CI.

@Ruiqi please assist with the runners if necessary. The kubectl error in the integration tests is strange

Hi @char-1ee I've already re-launched the runners, they should work fine now. But your codes still fail to pass these tests, please double check your codes and re-run the failed tests untill all of them are passed.
