[Propellor](https://propellor.branchable.com/) is a
configuration management system using Haskell and Git.
Each system has a list of properties, which Propellor ensures
[FreeBSD](http://propellor.branchable.com/FreeBSD/) are supported.
Propellor is configured via a git repository, which typically lives
in `~/.propellor/` on your development machine. Propellor clones the
repository to each host it manages, in a
[secure](http://propellor.branchable.com/security/) way. See
Properties are defined using Haskell in the file `~/.propellor/config.hs`.
There is fairly complete
which includes many built-in Properties for dealing with
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!
If using Haskell to configure Propellor seems intimidating,
see [configuration for the Haskell newbie](https://propellor.branchable.com/haskell_newbie/).
## quick start
1. Get propellor installed on your development machine (ie, laptop).
`cabal install propellor`
`stack install propellor`
`apt-get install propellor`
2. Run `propellor --init` ; this will set up a `~/.propellor/` git
repository for you.
3. Edit `~/.propellor/config.hs`, and add a host you want to manage.
You can start by not adding any properties, or only a few.
4. Run: `propellor --spin $HOST`
5. Now you have a simple propellor deployment to a host. Continue editing
`~/.propellor/config.hs` to further configure the host, add more hosts
etc, and re-run `propellor --spin $HOST` after each change.
6. Once you have a lot of hosts, and running `propellor --spin HOST` for
each host becomes tiresome, you can
7. Write some neat new properties and send patches!
