K8s中flexvolume插件驱动的安装只需要将对应驱动文件放到对应宿主机目录下，k8s 1.17及其之前需要重启kubelet组件生效

二进制集群环境默认路径：/usr/libexec/kubernetes/kubelet-plugins/volume/exec/<vendor~driver>/

Rancher集群环境默认路径：/var/lib/kubelet/volumeplugins/<vendor~driver>/

Install the vendor driver on all nodes (also on master nodes if "--enable-controller-attach-detach" Kubelet option is enabled) in the plugin path. Path for installing the plugin: <plugindir>/<vendor~driver>/<driver>. The default plugin directory is /usr/libexec/kubernetes/kubelet-plugins/volume/exec/. It can be changed in kubelet via the --volume-plugin-dir flag, and in controller manager via the --flex-volume-plugin-dir flag.

For example to add a cifs driver, by vendor foo install the driver at: /usr/libexec/kubernetes/kubelet-plugins/volume/exec/foo~cifs/cifs

The vendor and driver names must match flexVolume.driver in the volume spec, with '~' replaced with '/'. For example, if flexVolume.driver is set to foo/cifs, then the vendor is foo, and driver is cifs.
