Combining Ansible and Terraform for CI – better together love story based on OVN-CI project
summary
A CI workflow that uses Terraform to provision OpenStack test nodes and produce a dynamic Ansible inventory (example: two instances) and Ansible to configure them is described and shown working in OVN‑CI. Concrete techniques: terraform local_file + template to emit hosts.ini, ansible-terraform module registration to capture outputs into playbooks, and an ssh devtcp streaming hack for real-time log streaming. Terraform state gives reliable cleanup; ordering gather_facts after reachability avoids flaky runs.
