 * The path identifies a specific resource on the host. Paths have a hierarchical structure like

    * The deprecated `--resource-container` flag has been removed from kube-proxy, and specifying it will now cause an error.  The behavior is now as if you specified `--resource-container=""`.  If you previously specified a non-empty `--resource-container`, you can no longer do so as of kubernetes 1.16.
