Hi,
I installed the CentOS-Atomic-Host-7-Installer.iso 2018-06-11 on bare metal
and the latest Kubelet from
registry.centos.org/centos/kubernetes-sig-kubelet:latest I'm having trouble
starting Kubelet. I get this:
# systemctl -l status kubelet
● kubelet.service - kubernetes-kubelet
Loaded: loaded (/etc/systemd/system/kubelet.service; enabled; vendor
preset: disabled)

In /etc/kubernetes/kubelet I use:
KUBELET_ARGS="--cgroup-driver=systemd
--runtime-cgroups=/systemd/system.slice
--kubelet-cgroups=/systemd/system.slice --fail-swap-on=false"
Any ideas of what is going wrong here?
Thanks!
