Environment="KUBELET_CGROUP_ARGS=--cgroup-driver=systemd"I also checked the Environment with cli
$ systemctl show --property=Environment kubelet | catEnvironment=KUBELET_KUBECONFIG_ARGS=--kubeconfig=/etc/kubernetes/kubelet.conf\x20--require-kubeconfig=true KUBELET_SYSTEM_PODS_ARGS=--pod-manifest-path=/etc/kubernetes/manifests\x20--allow-privileged=true KUBELET_NETWORK_ARGS=--network-plugin=cni\x20--cni-conf-dir=/etc/cni/net.d\x20--cni-bin-dir=/opt/cni/bin KUBELET_DNS_ARGS=--cluster-dns=10.96.0.10\x20--cluster-domain=cluster.local KUBELET_AUTHZ_ARGS=--authorization-mode=Webhook\x20--client-ca-file=/etc/kubernetes/pki/ca.crt KUBELET_CADVISOR_ARGS=--cadvisor-port=0 KUBELET_CGROUP_ARGS=--cgroup-driver=systemd
KUBELET_CGROUP_ARGS=--cgroup-driver=systemd
