CFEngine 3 is a popular open source configuration management system. Its primary function is to provide automated configuration and maintenance of large-scale computer systems.
CFEngine is comprised of several source code repositories. As you might be looking for another part of the open source code base, here is a list to ease navigation:
- core (This repo) - The C source code for core components, like cf-agent and cf-serverd.
- libntech (submodule in core) - Library of reusable C code, such as data structures, string manipulation, JSON parsing, file handling, etc.
- core/contrib (subdirectory in core) - User-contributed tools and scripts
- masterfiles - The Masterfiles Policy Framework (MPF) contains the default policy (.cf) files
- documentation - Documentation on how CFEngine components work, the policy language, the enterprise features, etc.
- cf-remote - Tooling to make deploying / testing CFEngine across many remote instances easy
- buildscripts - Scripts and files needed to build installer packages across a wide variety of supported platforms
(Each repo also contains some supporting code/files, such as tests, scripts, documentation, etc.).
Pre-built installers are available from our website:
To install from source please see the INSTALL file for prerequisites and build instructions.

In order to use the built cf-agent in the source tree you must add a $HOME/.cfagent/bin/cf-promises file:
$ pwd
/core
$ echo "cd
The following code demonstrates simple CFEngine output through a reports promise.
bundle agent main
{
reports:
"Hello, world";
}
The following policy code may be executed with cf-agent (the main CFEngine binary) as follows.
$ cf-agent/cf-agent ./hello.cf
R: Hello, worldAs this project uses autotools you must use libtool to run gdb/lldb/debuggers
./libtool --mode=execute <gdb|lldb|yourdebugger> ./cf-agent/cf-agent
Please see the CONTRIBUTING.md file.
CFEngine 3 is not a drop-in upgrade for CFEngine 2 installations. It is a significantly more powerful version, but it is incompatible with the CFEngine 2 policy language.
The server part of CFEngine 3 supports the network protocol of CFEngine 2, so you may upgrade your installation gradually.
CFEngine was originally created by Mark Burgess with many contributions from around the world. Thanks everyone!
