svc/nginx-ingress-controller has

 53   - name: http-30010-lrzi1
 54     nodePort: 30043
 55     port: 30043
 56     protocol: TCP
 57     targetPort: 30043
 58   - name: https-30011-lrzi1
 59     nodePort: 30044
 60     port: 30044
 61     protocol: TCP
 62     targetPort: 30044

Also it added new entry to configmap, but i expect it to update existing entry.
