Ubuntu20.04无法启动kubelet的问题

查看状态

sudo systemctl status kubelet

会发现是exit 异常退出,查看日志

journalctl -u kubelet

发现如下报错

Failed to run kubelet" err="failed to run Kubelet: misconfiguration: kubelet cgroup driver: \"systemd\" is different from docker 
cgroup driver: \"cgroupfs\"

这是cgroup的驱动不必配导致的,本地docker使用的是cgroupfs,然而kubelet使用的是systemd

确认当前使用的驱动版本:

docker info |grep -i cgroup
WARNING: No swap limit support
 Cgroup Driver: cgroupfs
 Cgroup Version: 1

修改:

sudo vim /etc/docker/daemon.json

添加

{"exec-opts": ["native.cgroupdriver=systemd"]}

重启,搞定

sudo systemctl restart docker
