无法更改 Kubernetes 日志目录

Question

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 中所述）

# 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

在此之后我执行了命令：

systemctl daemon-reload
systemctl restart kubelet

连我都重启了kubeadm。但是日志目录位置仍然没有改变，它继续写入默认 /var/lib/kubelet 目录。我正在使用 Kubernetes version: v1.11.2。可能是什么问题？

Answer 1

我在 GCloud 上的一些机器上尝试过 v1.11.2 我也注意到了你的问题。

kubelet中的参数--log-dir好像没有作用

值得在kubelet项目中开一个issue。
