kubeadm init 에러 두번째

Question

kubeadm ini 했을때 에러가 첫번째는 /etc/kubernetes/manifests/ 아래에 있는 yaml 파일을 삭제하니 아래 에러는 처리됬습니다. -------------------- [ERROR FileAvailable--etc-kubernetes-manifests-kube-apiserver.yaml]: /etc/kubernetes/manifests/kube-apiserver.yaml already exists [ERROR FileAvailable--etc-kubernetes-manifests-kube-controller-manager.yaml]: /etc/kubernetes/manifests/kube-controller-manager.yaml already exists [ERROR FileAvailable--etc-kubernetes-manifests-kube-scheduler.yaml]: /etc/kubernetes/manifests/kube-scheduler.yaml already exists [ERROR FileAvailable--etc-kubernetes-manifests-etcd.yaml]: /etc/kubernetes/manifests/etcd.yaml already exists ===================================== 그러고 나니 아래 에러가 발생하네요.

mkdir /etc/docker cat <<EOF | sudo tee /etc/docker/daemon.json {   "exec-opts": ["native.cgroupdriver=systemd"],   "log-driver": "json-file",   "log-opts": {     "max-size": "100m"   },   "storage-driver": "overlay2" } EOF 위에 적용해보시고 kubeadm reset  후 kubeadm init 그래도 안된다면 kubeadm reset 후 리부팅 kubeadm init  하면 정상동작합니다. 안되면 리부팅한 후 다시하면 거의 되는거 같습니다.

안녕하세요 강사 최일선입니다. 답변이 늦어죄송합니다. 다음 문의는 빠르게 답변 드리도록 하곘습니다. ㅠ 일단 주신 내용으로 정보를 확인하기 어렵습니다. 데몬인 kubelet이 정상 구동되지 않은 것으로 보이는데 다음 명령어를 사용해 서비스의 로그를 확인해서 내용을 첨부해주시면 감사하겠습니다! journalctl -xeu kubelet 감사합니다.
