개요

Warning: short name "ev" could also match lower priority resource events.events.k8s.io

$ kubectl get ev
Warning: short name "ev" could also match lower priority resource events.events.k8s.io
LAST SEEN   TYPE      REASON    OBJECT      MESSAGE
2m7s        Normal    BackOff   pod/hello   Back-off pulling image "xxx"
2m7s        Warning   Failed    pod/hello   Error: ImagePullBackOff

약칭 ev는 core/v1의 events와 events.k8s.io/v1의 events 두 리소스에 모두 매칭된다. kubectl은 우선순위가 더 높은 core/v1의 events를 선택하여 출력하며, events.k8s.io/v1의 events도 매칭 대상이 될 수 있었음을 경고 메시지로 알린 것이다.

$ kubectl api-resources | grep -E 'NAME| ev '
NAME     SHORTNAMES   APIVERSION         NAMESPACED   KIND
events   ev           v1                 true         Event
events   ev           events.k8s.io/v1   true         Event

동일한 약칭(ev)이 서로 다른 두 API 그룹의 events 리소스에 중복 등록되어 있다.

두 Event 리소스는 내부 필드 구조가 다르며, events.k8s.io/v1은 레거시 필드를 deprecated* 접두어로 유지하고 있다.
