setup-openstack fails at upgrade check, placement API endpoint not found

[shaji khan]

Train (20.0.0)

- setup-openstack fails while deploying the first compute node.
- infra nodes seem to work fine
- Failure in nova-status upgrade check to validate a healthy configuration task
- The upgrade check fails for "Placement API endpoint not found"

I'm following https://docs.openstack.org/project-deploy-guide/openstack-ansible/train/overview.html and using a setup similar to Production Environment.

I could not find anything in the docs about how to configure the placement service. Any help will be much appreciated.

Thanks,

Update:

The current deployment guide and user guide (the openstack_user_config section) do not clarify that we need to add placement hosts as well; in the openstack_user_config.yml file.

# placement
placement-infra_hosts:
  infra1:
    ip: 172.29.236.11
and so on... if you have more than one hosts used for Placement service.

This is related to a patch for a fixed .example file here (Thanks to jrosser for clarifying): https://review.opendev.org/#/c/701548/1/etc/openstack_deploy/openstack_user_config.yml.test.example

Overall, if you had this fail during deployment:
- Be sure to add placement host(s) within openstack_user_config.yml
- rerun "setup-hosts.yml" then "setup-infrastructure.yml" then "setup-openstack.yml"

I guess we've added extra mentions to that in docs:
https://review.opendev.org/#/c/702934/
https://review.opendev.org/#/c/701548/

Also upgrade guide itself has mention to launch playbook with placement_upgrade variable set. Also there was an extra improval of upgrade script after 20.0.0 (iirc it's already in for 20.0.1) - https://review.opendev.org/#/c/710786/1

If you feel that we still missing mentioning somewhere in docs, please let us know about it (or place a fix :))
