인프런 커뮤니티 질문&답변

안녕하세요, 최근 질문을 많이 드리게 되네요!

이전 말씀해주신대로, Longhorn 관련 설정 수정 작업 진행 완료 했고 StatefulSet 관련하여 Pod를 늘리고 해당 Pod 안에서 touch 명령어로 파일을 생성하던 도중에 대시보드 서버가 먹통이 되었고

https://192.168.56.30:6443/

주소로 다시 접속을 하려 하면

아래와 같은 JSON 형식으로 에러가 발생하면서 접속이 되지 않습니다.]

혹시나 해서 대시보드를 삭제후 재설치를 하여도 여전히 같은 문제가 발생하는데요.

해당 대시보드를 재부팅하거나 대시보드를 다시 살릴수 있는 명령어 있을까요?

혹시나 해서 master 노드의 로그도 첨부드립니다.

[대시보드 삭제후 재설치 명령어]

# kubetm 가이드로 Dashboard대로 설치했을 경우 아래 명령으로 삭제
kubectl delete -f https://raw.githubusercontent.com/k8s-1pro/install/main/ground/k8s-1.27/dashboard-2.7.0/dashboard.yaml

# 다시 Dashboard (2.7.0) 설치 - <https://github.com/kubernetes/dashboard/releases/tag/v2.7.0>
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml
