This Ansible playbook collection provides scaffolding for automating launch and teardown of BDR node groups for testing purposes.

It's oriented toward testing from git, but can be easily adapted to test packaged releases too.

Currently it's focused on running BDR on multiple ports on the same host, but it's simply extensible to run on top of libvirt hosts (statically or dynamically provisioned), on AWS, etc.

Do not use this for any data you care about. It is entirely happy to rm -rf your data directory. This is a testing tool only.
