This is a work in progress configuration management system using Haskell
and Git.
The design is intentionally very bare bones: A git repository holds the
source to a program that ensures that the system meets a set of properties,
taking action as necessary when a property is not yet met.
Once set up, a system will have this git repository cloned to it, and
the program will be built and run periodically by a cron job. Or something
can ssh in and run it.
For bootstrapping, the program compiles to a single binary file,
which can be transferred to a host and run.
Properties are defined using Haskell. There is no special language as used
in puppet, chef, ansible, etc, just the full power of Haskell. Hopefully
that power can be put to good use in making declarative properties that are
powerful, nicely idempotent, and easy to adapt to a system's special needs.
Also avoided is any form of node classification. Ie, which hosts are part
of which classes and share which configuration. It might be nice to use
reclass[1], but then again a host is configured using simply haskell code,
and it should be easy to factor out things like classes of hosts in an
ad-hoc fashion.
