Hi Team, we tried OpenStack deployment using *Triple0 Wallaby.* while we were trying to deploy the setup Undercloud was deployed successfully. For the Overcloud Deployment: we generated the templates: Command: ./usr/share/openstack-tripleo-heat-templates/tools/process-templates.py -o ~/openstack-tripleo-heat-templates-rendered_at_wallaby -n /home/stack/templates/network_data.yaml -r /home/stack/templates/roles_data.yaml and using the below command to deploy overcloud: openstack overcloud deploy --templates \ -n /home/stack/templates/network_data.yaml \ -r /home/stack/templates/roles_data.yaml \ -e /home/stack/templates/environment.yaml \ -e /home/stack/templates/environments/network-isolation.yaml \ -e /home/stack/templates/environments/network-environment.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/services/ironic-conductor.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/services/ironic-inspector.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/services/ironic-overcloud.yaml \ -e /home/stack/templates/ironic-config.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/docker-ha.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/podman.yaml \ -e /home/stack/containers-prepare-parameter.yaml after which it fails with error: 2022-04-27 12:34:00.801 607453 ERROR tripleoclient.v1.overcloud_deploy.DeployOvercloud [-] Exception occured while running the command: ValueError: Failed to deploy: ERROR: HEAT-E99001 Service neutron is not available for* resource type OS::TripleO::Network::Ports::ControlPlaneVipPort, reason: neutron network endpoint is not in service catalog.* Traceback (most recent call last): we were able to deploy Triple0 Victoria/ Train /ussuri using the same approach. Please suggest any further changes needed to include in our setup. -Lokendra
