This application utilizes NETCONF south-bound plugin to manage NETCONF devices on the network. Application works as standalone SDN controller. It is capable to connect to NETCONF devices and expose connected devices over custom REST north-bound APIs. This demo shows how to run lighty.io in quarkus.io framework.
Application initializes OpenDaylight core components (MD-SAL, yangtools and controller) and NetConf Southbound plugin inside quarkus.io environment.
