Thanks angeloxx!

I'm following the kubernetes guide: https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/setup-ha-etcd-with-kubeadm/

In the instructions, they have you make a file: /usr/lib/systemd/system/kubelet.service.d/20-etcd-service-manager.conf

with the line:

ExecStart=/usr/bin/kubelet --address=127.0.0.1 --pod-manifest-path=/etc/kubernetes/manifests --cgroup-driver=systemd

I took your answer and added it to the end of the ExecStart line:

ExecStart=/usr/bin/kubelet --address=127.0.0.1 --pod-manifest-path=/etc/kubernetes/manifests --cgroup-driver=systemd --runtime-cgroups=/systemd/system.slice --kubelet-cgroups=/systemd/system.slice

I'm writing this in case it helps someone else

@ wolmi Thanks for the edit!

One more note: The config I have above is for my etcd cluster, NOT the kubernetes nodes. A file like 20-etcd-service-manager.conf on a node would override all the settings in the "10-kubeadm.conf" file, causing all kinds if missed configurations. Use the "/var/lib/kubelet/config.yaml" file for nodes and/or /var/lib/kubelet/kubeadm-flags.env.
