### Applications with Multiple Ports (segment labels)
Segment labels are used to define routes to an application exposing multiple ports.
A segment is a group of labels that apply to a port exposed by an application.
You can define as many segments as ports exposed in an application.
Additionally, if a segment name matches a named port, that port will be used unless `portIndex`, `portName`, or `port` labels are specified for that segment.
Segment labels override the default behavior.
