Kubernetes 如何更改RKE中的kubelet选项，如Rancher中的强制驱逐（nodefs.available、imagefs.available等）？

我仔细阅读了Kubernetes关于扩展默认15%的

imagefs.available

和其他参数的文档，但没有说明如何设置，我安装了RKE（Rancher Kubernetes引擎），配置如下

Kubernets Version:v1.17.5
OS: Ubuntu 18.04.4 LTS
Container Runtime: 19.3.9

顺便说一句，文档没有清楚地解释如何扩展默认驱逐，所以我来这里是想知道是否有人可以告诉我如何扩展它

我也试过kubelet命令行，但我得到了这个

补充资料 服务器（云、裸机等）：裸机 Kubernet安装使用：rancher

当我通过config.yaml使用rancher提供的kuberconfig文件执行此操作时，它会尝试在docker中而不是kubernets容器中逐出我的容器

我的命令是这样的 kubelet--kubeconfig=/root/.kube/config--config=/root/.kube/config.yaml

这正是我几个小时以来一直在寻找的东西，我在那个页面上滚动，但没有找到“编辑”，只有当你发送那个链接的时候。谢谢，现在我可以把我的产品放在现场而不是生产上了。很高兴能帮助我快速跟进此事。有没有办法只对某些特定的库贝莱人这样做？@JuanLeni没有。至少对RKE没有。如果您将kubelet[可能还有所有其他集群服务]作为系统服务运行，则可以根据需要对其进行配置。虽然实际上，如果希望不同的节点具有不同的配置，听起来您希望运行多个群集。请注意，设置这些设置中的任何一个都不会将新值与默认值合并，aka您需要显式地重新指定内存/索引节点/等的默认值。请参阅以获取默认值。非常感谢这正是我数小时来寻找的内容，我在该页面上滚动，但仅当您发送该链接时才发现“编辑”。谢谢，现在我可以把我的产品放在现场而不是生产上了。很高兴能帮助我快速跟进此事。有没有办法只对某些特定的库贝莱人这样做？@JuanLeni没有。至少对RKE没有。如果您将kubelet[可能还有所有其他集群服务]作为系统服务运行，则可以根据需要对其进行配置。虽然实际上，如果希望不同的节点具有不同的配置，听起来您希望运行多个群集。请注意，设置这些设置中的任何一个都不会将新值与默认值合并，也就是说，您需要显式地重新指定内存/索引节点/等的默认值。有关默认值，请参阅。
