쿠버네티스 클러스터 구축시 CRI 에러

[preflight] Running pre-flight checks.

[preflight] Some fatal errors occurred:

        [ERROR CRI]: unable to check if the container runtime at "/var/run/dockershim.sock" is running: fork/exec /usr/bin/crictl -r /var/run/dockershim.sock info: no such file or directory

[preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...`

centos7 환경에서 했구요 vm으로 구축중입니다

kubeadm join  을 워커노드 만들려고 하는 곳에 했는데 이런 에러가 발생 합니다 

로그는 워커노드에서 복사한것입니다  

--ignore 옵션을 줘서 했는데 마스터노드에서 kubectl get nodes 를 했을때 worker노드가 안나와서 

이 문제를 해결해야될거 같아서 질문합니다

일단 kubelet 했을때 에러가

가 나와서 

1.

/etc/systemd/system/kubelet.service.d/10-kubeadm.conf 에

Environment="KUBELET_CGROUP_ARGS=--cgroup-driver=systemd“   

추가 하고 

systemctl show --property=Environment kubelet | cat 

확인 후에 했는데도

에러가 나와서

 다른 곳은 systemd로 수정했는데도 다르다고 나오기도하고  cri에러와  kubelet에 에러가 나와서 질문 합니다 .
