无法更改kubernetes日志目录

我想更改kubelet日志目录位置。为了达到同样的目的,我修改了 /etc/systemd/system/kubelet.service.d/10-kubeadm.conf 文件内容如下(如 how to change kubelet working dir to somewhere else )

# Note: This dropin only works with kubeadm and kubelet v1.11+
[Service]
Environment="KUBELET_KUBECONFIG_ARGS=--bootstrap-kubeconfig=/etc/kubernetes/bootstrap-kubelet.conf --kubeconfig=/etc/kubernetes/kubelet.conf"
Environment="KUBELET_CONFIG_ARGS=--config=/var/lib/kubelet/config.yaml"
Environment="KUBELET_EXTRA_ARGS=--root-dir=/D/kubelet-files/ --log-dir=/D/kubelet-logs/"
# This is a file that "kubeadm init" and "kubeadm join" generates at runtime, populating the KUBELET_KUBEADM_ARGS variable dynamically
EnvironmentFile=-/var/lib/kubelet/kubeadm-flags.env
# This is a file that the user can use for overrides of the kubelet args as a last resort. Preferably, the user should use
# the .NodeRegistration.KubeletExtraArgs object in the configuration files instead. KUBELET_EXTRA_ARGS should be sourced from this file.
EnvironmentFile=-/etc/sysconfig/kubelet
ExecStart=
ExecStart=/usr/bin/kubelet $KUBELET_KUBECONFIG_ARGS $KUBELET_CONFIG_ARGS $KUBELET_EXTRA_ARGS $KUBELET_KUBEADM_ARGS

之后我执行命令:

systemctl daemon-reload
systemctl restart kubelet

即使我重新开始 kubeadm 是的。但仍然记录目录位置没有改变,它继续写入默认值 /var/lib/kubelet 目录。我在用 Kubernetes version: v1.11.2 是的。可能是什么问题?
