Am trying to setup kubernetes in centos machine, kubelets start is giving me this error.
Failed to get kubelets cgroup: cpu and memory cgroup hierarchy not unified. Cpu:/, memory: /system.slice/kubelet.service.
The cgroup driver I mentioned is systemd for both docker and kubernetes
Docker version 1.13.1
Kubernetes version 1.15.2
Can any one suggest the solution.
This issue is fixed in a commit but still not merged see this
you may try this work around:
sudo vim /etc/sysconfig/kubelet
add at the end of DAEMON_ARGS string:
--runtime-cgroups=/systemd/system.slice --kubelet-cgroups=/systemd/system.slice
restart:
sudo systemctl restart kubelet
or :
adding a file in : /etc/systemd/system/kubelet.service.d/11-cgroups.conf
which contains:
[Service]
CPUAccounting=true
MemoryAccounting=true
then reload and restart
systemctl daemon-reload && systemctl restart kubelet
