Note
This document is a work-in-progress. Unfilled sections will be worked in follow-up patchsets. This version is to get a basic outline and index done so that we can then build on it. (krtaylor)
This document provides tips and guidelines for third-party driver developers setting up their continuous integration test systems.

Problem¶
If you are using actual hardware as target machines for your CI testing then the problem of two jobs trying to use the name target arises. If you have one target machine and a maximum number of one jobs running on your ironic pipeline at a time, then you won’t run into this problem. However, one target may not handle the load of ironic’s daily patch submissions.
Solutions¶
Zuul v3¶
Molten Iron¶
molteniron is a tool that allows you to reserve hardware from a pool at the last minute to use in your job. Once finished testing, you can unreserve the hardware making it available for the next test job.
