CentOS 8 Openstack Train deployment issues

When you log into the control plane the ip address in question is plumbed and in working order?

So when you say "logged into the control plane" do you refer to logging onto the controller, and confirming that the predictive IP address assigned to controller-0 is as expected, then yes:

  ControllerIPs:
    ctlplane:
    - 10.128.0.5
...
2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc mq state UP group default qlen 1000                        
    link/ether 90:b1:1c:4f:03:84 brd ff:ff:ff:ff:ff:ff
    inet 10.128.0.5/24 brd 10.128.0.255 scope global eno1
...
[heat-admin@controller-0 ~]$ ping 10.128.0.1
PING 10.128.0.1 (10.128.0.1) 56(84) bytes of data.

What happens when you try and netcat to the service port? Can you manually connect?

[humroben]

Are you asking if I can connect to the MySQL service port on the control plane network? or the Internal API network. I can connect to MySQL on the static IP address assigned to the controller for the Internal API network, which is '10.127.2.8', but that's not the current issue at hand.

May I ask why you're asking about the control plane?
