- For the OpenShift provider, a route is created.
- `kompose.service.nodeport.port` defines the port value when service type is `nodeport`, this label should only be set when the service only contains 1 port. Usually kubernetes define a port range for node port values, kompose will not validate this.
- `kompose.service.expose.tls-secret` provides the name of the TLS secret to use with the Kubernetes ingress controller. This requires kompose.service.expose to be set.
- `kompose.service.expose.ingress-class-name` provides the name of ingress class to use with the Kubernetes ingress controller. This requires kompose.service.
