kubelet이 kubeadm init에서 실행되지 않거나 정상 상태가 아닙니다.

에 문제가 있습니다 kubeadm init. 우선 이 문제가 있었고 해결 방법을 진행했습니다. https://stackoverflow.com/questions/41732265/how-to-use-kubeadm-to-create-kubernetes-cluster

내 오류가 다음과 같이 변경되었습니다.

sudo swapoff -a그런 다음 이전 프로세스를 실행 하고 다시 시도했는데 이제 이 오류가 다시 발생합니다.

[preflight] Running pre-flight checks
error execution phase preflight: [preflight] Some fatal errors occurred:

[preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...`
To see the stack trace of this error execute with --v=5 or higher

그리고 나는 도커가 실행되고 있는지 전혀 모릅니다. 어떤 해결책이라도 도와주실 수 있나요? 정확히 문제가 무엇인가요?

포트 10250이 사용 중이라는 것은 일반적으로 "kubeadm Reset"을 재설정해야 함을 의미합니다.
