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.
