Trying to deploy Tripleo (qeeens) with ovn enabled.. Following (my interpretation of) the Redhat OS13 docs I have.. (Note: Im just using the RHOS13 docs as reference. Im deploying upstream/opensource queens)

  1. modified my compute NIC config to include the External network / vlan.
  2. modified environments/network-isolation.yaml to add the OS::TripleO::Compute::Ports::ExternalPort:
  3. modified environments/ips-from-pool-all.yaml to add the OS::TripleO::Compute::Ports::ExternalPort:
  4. modified (my env file) templates/fixed-ips.yaml to add relevant IPs (for ComputeIPs: / external:)

But the deploy is failing (step: overcloud.Compute.1.NetworkDeployment:) .. On my compute nodes if I examine /etc/os-net-config/config.json it looks like the (fixed) external IP is not being assigned.. (vlan10 is my external vlan)

[heat-admin@compute0 ~]$  cat /etc/os-net-config/config.json | jq ".network_config[3]"
  "members": [
      "name": "nic4",
      "primary": true,
      "type": "interface"
      "addresses": [
          "ip_netmask": ""
      "routes": [
          "default": true,
          "next_hop": ""
      "type": "vlan",
      "vlan_id": 10
  "name": "br-ex",
  "type": "ovs_bridge",
  "use_dhcp": false
[heat-admin@compute0 ~]$

The vlan and next_hop look good..

I seem to be missing something to get the IP address assigned..

Any clues ??

I'm not sure if I'm heading in the right direction. Ive included a roles_data.yaml file that has the Compute role including the External network. Compute seems to get further as compute nodes now have (fixed) External IP's. (Compute) Now bombs out during docker-puppet tasks (generate config)

Closing this question as adding the External Network to the compute role resolved the fixed ip allocation issue.
