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"

原因：kubernetes和docker版本兼容性问题

解决方法：修改kubelet配置文件

vim /etc/systemd/system/kubelet.service.d/10-kubeadm.conf 
#找到 KUBELET_CGROUP_ARGS=–cgroup-driver=systemd 在后面增加以下内容： 
–runtime-cgroups=/systemd/system.slice –kubelet-cgroups=/systemd/system.slice 
Environment=”KUBELET_CGROUP_ARGS=–cgroup-driver=systemd –runtime-cgroups=/systemd/system.slice –kubelet-cgroups=/systemd/system.slice”

保存之后，重启kubelet服务即可

systemctl daemon-reload 
systemctl restart kubelet

确定要放弃本次机会？

阿里云ack集群的话可以在/etc/systemd/system/kubelet.service.d/10-kubeadm.conf中添加这两个环境变量。在/etc/systemd/system/kubelet.service中配置。：配置CPUAccounting、MemoryAccounting环境变量。系统：CentOS 7.4。

kubernetes和docker版本兼容性问题 1、vim /etc/systemd/system/kubelet.service.d/10-kubeadm.conf 这是kubeadm部署模式的启动文件 2、找到对应的EnvironmentFile配置启动参数的文件 3、修改/etc/sysconfig/kubelet文件追加 KUBELET_EXTRA_ARGS=--runtime-cgroups=/systemd/system.slice --kubelet-cgroups=/systemd/sys

解决方案：修改docker，只需在/etc/docker/daemon.json中，添加"exec-opts": [“native.cgroupdriver=systemd”]即可，本文最初的docker配置可供参考。解决方案：apiserver中指定的etcd服务配置错误，检查配置修改即可。解决方案：kubectl config 配置错误，检查修改。解决方案：这是因为kube-apiserver的RBAC。解决方案：在kubelet中追加配置。controller日志。apiserver日志。
