@ashutshkumr Steps to config, create & delete topology:

1. Deploy operator container
   docker run -d --privileged -v /var/run/docker.sock:/var/run/docker.sock --pid=host --net=host --user=root --name=operator --server-bind-address=:35000
2. Load configmap
   curl --data-binary @ixia-configmap.yaml http://localhost:35000/config
3. Create topology (ensure the requisite network interfaces exists on the host)
   curl -d @lagport http://localhost:35000/create
4. Delete topology
   curl -d @lagport http://localhost:35000/delete
