2) copy instackenv.json from undercloud to /infrared in ansible/infrared node

3) in undercloud /home/stack/network_data.yaml

5) infrared plugin add plugins/tripleo-overcloud

6) run overcloud command

ile /infrared/instackenv.json  --extra-deploy-params="-n /home/stack/network_data.yaml" 2>&1 | tee ir_oc14_log1.txt
