Hi Harald/Julia/Openstack Team I had successfully installed Ironic Service in Tripleo Train, Ussuri Release with the help of openstack discuss team members. https://lists.openstack.org/pipermail/openstack-discuss/2022-February/027047... I had custom network configuration for which I had passed Service net map as below in network-environment file. parameter_defaults: ServiceNetMap: IronicApiNetwork: oc_provisioning IronicNetwork: oc_provisioning But with the Wallaby Release, since the deployment format has changed There is no network-environment file. So I tried passing it in a separate environment.yaml file along with the templates. Command to deploy in wallaby: openstack overcloud deploy --templates \ --networks-file /home/stack/templates/custom_network_data.yaml \ --vip-file /home/stack/templates/custom_vip_data.yaml \ --baremetal-deployment /home/stack/templates/overcloud-baremetal-deploy.yaml --deployed-server \ --network-config \ -e /home/stack/templates/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/services/ptp.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 Without Service Net Map, deployment was successful but TFTP of image was an issue since we are going with custom network approach. Passing Service Net map details in a seperate file environment.yaml, is giving the below error: 24d-f43f-6f76-000000006ce9 | TASK | Create containers managed by Podman for /var/lib/tripleo-config/container-startup-config/step_3 2022-06-07 11:16:46.806982 | | WARNING | ERROR: Can't run container ironic_db_sync stderr: Error: statfs /var/lib/config-data/puppet-generated/ironic_api: no such file or directory 2022-06-07 11:16:46.809252 | 525400fd-f24d-f43f-6f76-000000006c79 | FATAL | Create containers managed by Podman for /var/lib/tripleo-config/container-startup-config/step_3 | overcloud-controller-1 | error={"changed": false, "msg": "Failed containers: ironic_db_sync"} 2022-06-07 11:16:46.810197 | 525400fd-f24d-f43f-6f76-000000006c79 | TIMING | tripleo_container_manage : Create containers managed by Podman for /var/lib/tripleo-config/container-startup-config/step_3 | overcloud-controller-1 | 0:11:40.574944 | 10.62s 2022-06-07 11:16:47.683400 | | WARNING | ERROR: Can't run container ironic_db_sync stderr: Error: statfs /var/lib/config-data/puppet-generated/ironic_api: no such file or directory 2022-06-07 11:16:47.684455 | 525400fd-f24d-f43f-6f76-000000006ce9 | FATAL | Create containers managed by Podman for /var/lib/tripleo-config/container-startup-config/step_3 | overcloud-controller-2 | error={"changed": false, "msg": "Failed containers: ironic_db_sync"} Can you please suggest the place we can pass the service net map details in Wallaby Release to resolve this issue?
