今天查看kubelet日志的时候，发信一堆报错：
查看kubelet日志：

网上搜了一堆，大致原因是kubernetes和docker版本兼容性问题，查看docker版本
]# docker info Client: Debug Mode: false Server: Containers: 34 Running: 26 Paused: 0 Stopped: 8 Images: 77 Server Version: 19.03.13 Storage Driver: overlay2 Backing Filesystem: xfs Supports d_type: true Native Overlay Diff: true Logging Driver: json-file Cgroup Driver: cgroupfs
网上方法：
在10-kubeadm.conf文件中"KUBELET_CGROUP_ARGS"属性添加"--runtime-cgroups=/systemd/system.slice --kubelet-cgroups=/systemd/system.slice" ，如果不存在"KUBELET_CGROUP_ARGS"属性则新增。
10-kubeadm.conf的路径网上提到的多为：/etc/systemd/system/kubelet.service.d/10-kubeadm.conf
而我的K8S尝试了之后并不好使（应该是我的版本太低），并且kubelet启动失败
按照以下方法修改后报错消失
]# vim /etc/sysconfig/kubelet KUBELET_EXTRA_ARGS="--runtime-cgroups=/systemd/system.slice --kubelet-cgroups=/systemd/system.slice"
重新加载配置文件
systemctl daemon-reload systemctl restart kubelet
