This issue is fixed in a commit but still not merged see this

您可以尝试以下解决方法:

you may try this work around:

sudo vim /etc/sysconfig/kubelet

在DAEMON_ARGS字符串的末尾添加:

add at the end of DAEMON_ARGS string:

 --runtime-cgroups=/systemd/system.slice --kubelet-cgroups=/systemd/system.slice

重新启动:

sudo systemctl restart kubelet

或:

在/etc/systemd/system/kubelet.service.d/11-cgroups.conf

其中包含:

[Service]
CPUAccounting=true
MemoryAccounting=true

然后重新加载并重新启动

then reload and restart

systemctl daemon-reload && systemctl restart kubelet
