Bcfg2: Open-Source Configuration Management System

A highly scalable and customizable solution for maintaining computer configurations, enabling administrators to define desired states and automatically correct discrepancies

What is Bcfg2?

Bcfg2 is an open-source configuration management system created to help system administrators maintain consistent configurations across a large number of computers. It was originally developed to manage Linux/UNIX systems but also supports managing Windows, Mac OS X, network devices and more.

Bcfg2 allows administrators to define the desired configuration states for various components of a system, like packages that should be installed, services that should be enabled/disabled, or files that should have specific contents. These desired states are defined in a structured way using XML, Python, YAML or JSON.

The Bcfg2 server then connects to all managed clients periodically and audits their current configuration. Any differences between the actual state and the defined desired state, referred to as 'configuration drift', is automatically corrected by installing/updating packages, modifying config files, enabling services etc. This helps ensure consistency and compliance to defined policies.

Key capabilities include:

  • Flexible and extendable architecture
  • idempotent configuration enforcement
  • configuration drift detection and remediation
  • structured configuration specifications
  • server/client architecture for scalability
  • reporting and auditing

Bcfg2 can integrate with other systems like LDAP, Amazon EC2, GitHub, automation tools through its plugins. It is used to enforce security compliance, track changes, and speed up provisioning of software configurations across an entire IT infrastructure.
