as the graph, I have a controller node with "objecas.sdfadsf.sdfs.com" domain name and two NIC, one connect to internet and one to the internal compute nodes, this also applies to the Network node I am confused about the part at kolla-ansible when setting the following:

kolla_internal_vip_address,

kolla_internal_fqdn,

kolla_external_vip_address,

kolla_external_fqdn,

network_interface,

neutron_external_interface,

I will be really appreciated if anyone can help with how to set up the configuration according to my server set, thank you!

I think this is well documented at https://github.com/openstack/kolla-an.... I suppose your external addresses start with 141, and the internal ones with 192. The VIPs are free addresses from those ranges, and the FQDNs can be the addresses.

i.e. no need to invent FQDNs.

network_interface is for APIs, network_external_interface for external instance access. In your case, both eth1 I guess.

Thank you so much, sir! If my controller node NIC 141.142.204.9 has a domain name http://object.ncsa.illinois.edu, how can I make this a dashboard? should I put "141.142.204.9" as my kolla_external_vip_address? but my controller node public IP is 141.142.204.9, is this a conflict? thank you so much!

Read the documentation. What I understand: Normally, the external VIP should be an unused IP address on your external network. If, however, you have no HA, which seems to be your case, set it to the address of the external interface.
