안녕하세요 kubelet 실행시 cgroup driver가 cgroupfs로 나옵니다
14일 전
failed to run Kubelet: misconfiguration: kubelet cgroup driver: "cgroupfs" is different from docker cgroup driver: "systemd"
공식문서에는 이 위치에 파일을 찾으라해서 찾았는데
/etc/systemd/system/kubelet.service 위치에 없어서 찾다보니
vi /etc/systemd/system/kubelet.service.d/10-kubeadm.conf 에
Environment="KUBELET_CGROUP_ARGS=--cgroup-driver=systemd“ 추가 했는데도
kubelet cgroup driver가 cgroupfs로 되는 문제가 있는데 어떻게 해야되나요?
kubelet log 입니다
kubelet 실행시 로그입니다
