JSON file for the import the overcloud nodes
Creation of the JSON file for the overcloud nodes.
This JSON File will be used to import the overcloud VirtualMachines as the baremetal nodes on the undercloud server.
And later on, to these machines the overcloud deploy will happen.
instackenv.json for 3 controllers, 3 compute and 3 ceph-storage baremetals
Please note that there is 1 to 1 mapping of the MAC addresses (hence the virtual machines) to the Ports(UDP).

You should always validate the JSON for the syntax error and hence this file has to be a valid JSON.
You can validate it using
cat instackenv.json | python -m json.tool
In case the file has JSON Syntax error, it is going to error out. Else the JSON for the undercloud.conf is good.
Import the Virtual Servers as the baremetal nodes to the undercloud server .
Import of the overcloud VirtualMachines as the baremetal nodes in the undercloud. Please note After the successful import the nodes come in the manageable state.
openstack overcloud node import --run-validations --instance-boot-option lcoal instackenv.json
Nodes set to managed.

You can validate that the nodes have been imported as they start showing up as the openstack baremetal servers.
Run the below and see the list and you can see that the servers are in the 'manageable' state
