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.

[wait-control-plane] Waiting for the kubelet to boot up the control plane as static Pods from directory "/etc/kubernetes/manifests". This can take up to 4m0s

[kubelet-check] Initial timeout of 40s passed.

[kubelet-check] It seems like the kubelet isn't running or healthy.

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.
