Golang AttributesRecord.Subresource方法代码示例

// GetRequestAttributes populates authorizer attributes for the requests to the kubelet API.
// Default attributes are: {apiVersion=v1,verb=<http verb from request>,resource=nodes,name=<node name>,subresource=proxy}
// More specific verb/resource is set for the following request patterns:
//    /stats/*   => verb=<api verb from request>, resource=nodes, name=<node name>, subresource=stats
//    /metrics/* => verb=<api verb from request>, resource=nodes, name=<node name>, subresource=metrics
//    /logs/*    => verb=<api verb from request>, resource=nodes, name=<node name>, subresource=log
//    /spec/*    => verb=<api verb from request>, resource=nodes, name=<node name>, subresource=spec
