- Set up TripleO-quickstart undercloud (works-for-me via master.sh)
- Deploy juice-boxes (works-for-me via deploy-jeos.sh)
- Run mistral-ceph-ansible.sh which executes the workflow mistral-ceph-ansible.yaml
I have verified that the above works in my virtual environment. The run takes less than 30 minutes. An example is in session1.txt.
- Use deploy-mistral-ceph-hci.sh to deploy OpenStack to use an external Ceph cluster (which it will self-host)
- If the playbook is configured to use br-ex instead of eth0, then the same mistral workflow will install Ceph on the same hosts.
- Then you just need to restart nova, cinder, and glance to have those services use Ceph and you can do a sanity-check.sh.
see session2.txt.

The following deploys such an overcloud provided that init.sh has been run first.
[stack@undercloud tripleo-ceph-ansible]$ cat deploy.sh

- Use OS::Mistral::WorflowExecution to start the workflow so all I need to do is
openstack overcloud deploy ...(Goal2) - Use ceph-ansible docker to deploy Ceph in containers [ done ].
- Use Containerized Compute
- Use External Ceph to make the overcloud talk to the CephCluster stood up on overcloud nodes without OpenStack services.
Then all I would need to do is insert Tendrl in between Mistral and Ceph-Ansible and I would have implemented the main goal of the spec Integrate TripleO with Tendrl for External Storage Deployment/Management.
Assuming the the controller portion of the spec Deploying TripleO in Containers is finished, then I could converge them as follows:
- ContainerHost{1,2,3}: 2 containers: CephMon and OpenStackController
- ContainerHost{4..N}: 2 containers: NovaCompute and CephOSD
