I'm using the tripleo standalone install to set up an Ironic test environment. With recent tripleo master, the deploy started failing because the DockerOvn*Image parameters weren't defined. Here's what I did to get everything working:
1. I added to my deploy:
-e /usr/share/tripleo-heat-templates/environment/services/neutron-ovn-standalone.yaml
With this change, `openstack tripleo container image prep` correctly detected that ovn was enabled and generated the appropriate image parameters.
2. environments/services/ironic.yaml sets:
NeutronMechanismDrivers: ['openvswitch', 'baremetal']
Since I didn't want openvswitch enabled in this deployment, I explicitly set the mechanism drivers in a subsequent environment file:
NeutronMechanismDrivers: ['ovn', 'baremetal']
3. The neutron-ovn-standalone.yaml environment explicitly disables the non-ovn neutron services. Ironic requires the services of the neutron_dhcp_agent, so I had to add:
OS::TripleO::Services::NeutronDhcpAgent: /usr/share/openstack-tripleo-heat-templates/deployment/neutron/neutron-dhcp-container-puppet.yaml
With this in place, the ironic nodes were able to receive dhcp responses and were able to boot.
3. In order to provide the baremetal nodes with a route to the nova metadata service, I added the following to my deploy:
NeutronEnableForceMetadata: true
This provides the baremetal nodes with a route to 169.254.169.254 via the neutron dhcp namespace.
4. In order get the metadata service to respond correctly, I also had to enable the neutron metadata agent:
OS::TripleO::Services::NeutronMetadataAgent: /usr/share/openstack-tripleo-heat-templates/deployment/neutron/neutron-metadata-container-puppet.yaml
This returned my Ironic deployment to a functioning state: I can successfully boot baremetal nodes and provide them with configuration information via the metadata service.
I'm curious if this was the *correct* solution, or if there was a better method of getting things working.
I think you're hitting https://bugs.launchpad.net/tripleo/+bug/1816663 Dan has proposed a patch https://review.openstack.org/#/c/637989/. This is a side effect of switch to ovn by default i believe
