Developer's Guide
Getting Started
If you are new to ironic, this section contains information that should help you get started as a developer working on the project or contributing to the project.

The following pages describe the architecture of the Bare Metal service and may be helpful to anyone working on or with the service, but are written primarily for developers.

These pages contain information for PTLs, cross-project liaisons, and core reviewers.

Writing Drivers
Ironic's community includes many hardware vendors who contribute drivers that enable more advanced functionality when Ironic is used in conjunction with that hardware. To do this, the Ironic developer community is committed to standardizing on a Python Driver API that meets the common needs of all hardware vendors, and evolving this API without breaking backwards compatibility. However, it is sometimes necessary for driver authors to implement functionality - and expose it through the REST API - that can not be done through any existing API.
To facilitate that, we also provide the means for API calls to be "passed through" ironic and directly to the driver. Some guidelines on how to implement this are provided below. Driver authors are strongly encouraged to talk with the developer community about any implementation using this functionality.

Testing Network Integration
In order to test the integration between the Bare Metal and Networking services, support has been added to devstack to mimic an external physical switch. Here we include a recommended configuration for devstack to bring up this environment.

Testing Boot-from-Volume
Starting with the Pike release, it is also possible to use DevStack for testing booting from Cinder volumes with VMs.
