Hi Team, I am trying to deploy TripleO Train with 3 controller and 1 Compute. For overcloud images, I have a registry server at undercloud only. I executed the following command to deploy overcloud openstack overcloud deploy --templates \ -r /home/stack/templates/roles_data.yaml \ -e /home/stack/templates/node-info.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/podman.yaml \ -e /home/stack/containers-prepare-parameter.yaml The command ran for around 1.5 hrs and initially stack got successfully created and after that for 45 mins, ansible tasks were getting executed. It then gave following error in overcloud-controller-0 2021-12-27 11:12:27,507 p=181 u=mistral n=ansible | 2021-12-27 11:12:27.506838 | 525400b1-b522-2a06-ea9d-00000000356f | OK | Debug output for task: Start containers for step 2 | overcloud-novacompute-0 | result={ "changed": false, "failed_when_result": false, "start_containers_outputs.stdout_lines | default([]) | union(start_containers_outputs.stderr_lines | default([]))": [ "f206c31a781641313aa4a0499c62475efc335de6faea785cd4e855dc32ebb571", "", "Info: Loading facts", "Notice: Compiled catalog for overcloud-novacompute-0.localdomain in environment production in 0.05 seconds", "Info: Applying configuration version '1640604309'", "Notice: /Stage[main]/Tripleo::Profile::Base::Neutron::Ovn_metadata_agent_wrappers/Tripleo::Profile::Base::Neutron::Wrappers::Haproxy[ovn_metadata_haproxy_process_wrapper]/File[/var/lib/neutron/ovn_metadata_haproxy_wrapper]/ensure: defined content as '{md5}5bb050ca70c01981975efad9d8f81f2d'", "Info: Tripleo::Profile::Base::Neutron::Wrappers::Haproxy[ovn_metadata_haproxy_process_wrapper]: Unscheduling all events on Tripleo::Profile::Base::Neutron::Wrappers::Haproxy[ovn_metadata_haproxy_process_wrapper]", "Info: Creating state file /var/lib/puppet/state/state.yaml", "Notice: Applied catalog in 0.01 seconds", "Changes:", " Total: 1", "Events:", " Success: 1", "Resources:", " Changed: 1", " Out of sync: 1", " Skipped: 7", " Total: 8", "Time:", " File: 0.00", " Transaction evaluation: 0.01", " Catalog application: 0.01", " Config retrieval: 0.09", " Last run: 1640604309", " Total: 0.01", "Version:", " Config: 1640604309", " Puppet: 5.5.10", * "Error executing ['podman', 'container', 'exists', 'nova_compute_init_log']: returned 1", "Did not find container with \"['podman', 'ps', '-a', '--filter', 'label=container_name=nova_compute_init_log', '--filter', 'label=config_id=tripleo_step2', '--format', '{{.Names}}']\" - retrying without config_id", "Did not find container with \"['podman', 'ps', '-a', '--filter', 'label=container_name=nova_compute_init_log', '--format', '{{.Names}}']\"", "Error executing ['podman', 'container', 'exists', 'create_haproxy_wrapper']: returned 1", "Did not find container with \"['podman', 'ps', '-a', '--filter', 'label=container_name=create_haproxy_wrapper', '--filter', 'label=config_id=tripleo_step2', '--format', '{{.Names}}']\" - retrying without config_id", "Did not find container with \"['podman', 'ps', '-a', '--filter', 'label=container_name=create_haproxy_wrapper', '--format', '{{.Names}}']\""* ] } I am also attaching ansible.log file for more information. Note: On Centos 8, there is no docker, so I didn't pass docker-ha.yml Can someone please help in resolving my issue Regards Anirudh Gupta
