报错内容如下:

FAIled to get system container stats for “/system.slice/kubelet.service”: failed to get cgroup stats for “/system.slice/kubelet.service”: failed to get container info for “/system.slice/kubelet.service”: unknown container “/system.slice/kubelet.service” Failed to getsystem container statsfor “/system.slice/docker.service”: failed to get cgroup stats for “/system.slice/docker.service”: failed to get container info for “/system.slice/docker.service”: unknown container “/system.slice/docker.service”

编辑配置文件新增如下内容:

重启机器后

[root@master-all ~]# systemctl restart kubelet 报错内容 Failed to getsystem container statsfor “/user.slice/user-0.slice/session-1.scope”: failed to get cgroup stats for “/user.slice/user-0.slice/session-1.scope”: failed to get container info for “/user.slice/user-0.slice/session-1.scope”: unknown container“/user.slice/user-0.slice/session-1.scope”
