노드 스캐줄링 질문

노드 스캐줄링 실습중

error: error validating "podsch.yaml": error validating data: ValidationError(Pod.spec.containers[0]): unknown field "terminationGracePeriodSeconds" in io.k8s.api.core.v1.Container; if you choose to ignore these errors, turn validation off with --validate=false

이런 에러가 계속 발생하는데 원인이 뭘까요..

야믈 파일과 노드 상태입니다.

라벨링도  했구요.
