Yes it is possible.

You have two choices, either to deploy ceph yourself and integrate it with openstack-ansible by providing a reference to the ceph monitors, or you can have openstack-ansible act as a thin wrapper around ceph-ansible to deploy ceph at the same time as openstack.

Having said this - I would not recommend doing a converged deployment like this other than for test purposes.

It's slightly unclear if you want an entire deployment with ceph in a single node, if that is the case then you can look at the all-in-one deployment here https://docs.openstack.org/openstack-ansible/latest/user/aio/quickstart.html, configured with the environment variable SCENARIO=aio_lxc_ceph. This is strictly a test environment (exactly what we use for our CI tests) and not a production deployment.

Hello everyone!

Is it possible with OpenStack-Ansible to deploy converged nova compute and ceph storage on a single node?

Thank you!
