Digital Rebar
~~~~~~~~~~~~~

*simple, fast and open-ecosystem infrastructure automation with strong Infrastructure as Code (IaC) design.*

`Digital Rebar (aka DRP) <http://rebar.digital>`_ is a `RackN <https://rackn.com>`_ licensed-core platform with an open ecosystem suite of both licensed and open `APLv2 <https://raw.githubusercontent.com/digitalrebar/provision/v4/LICENSE>`_ components.  The fourth generation platform provides a simple yet complete API-driven DHCP/PXE/TFTP provisioning and workflow system.

Digital Rebar Platform and Ecosystem are designed together to be a complete data center provisioning, content scaffolding and infrastructure workflow platform with a cloud native architecture that completely replaces Cobbler, Foreman, MaaS, Ironic or similar technologies. DRP offers a single golang binary (less than 30MB) with no dependencies capable of installation on a laptop, RPi or switch supporting both bare metal and virtualized infrastructure.

Key Features:

  Platform Capabilities:
    * API-driven infrastructure-as-code automation
    * Multi-boot workflows using composable and reusable building blocks
    * Event driven actions via Websockets API
    * Extensible Plug-in Model for public, vendor and internal enhancements
    * Dynamic Workflow Contexts (allows using APIs when agents cannot be run)
    * Distributed Multi-Site Management
    * Integrated Secure Boot, SSO and Highly Available options.
    * Supports ALL orchestration tools including Chef, Puppet, Ansible, SaltStack, Bosh, Terraform, etc

  Open Ecosystem Plugins:

    * Cloud-like pooling capabilities
