Propellor is a configuration management system using Haskell and Git. Each system has a list of properties, which Propellor ensures are satisfied.
Propellor is configured via a git repository, which typically lives
~/.propellor/ on your development machine. Propellor clones the
repository to each host it manages, in a
secure way. See components
Properties are defined using Haskell. Edit
to get started. 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.
- Get propellor installed on your development machine (ie, laptop).
cabal install propelloror
apt-get install propellor
propellorfor the first time. It will set up a
~/.propellor/git repository for you.
- If you don't have a gpg private key already, generate one:
propellor --add-key $KEYID, which will make propellor trust your gpg key, and will sign your
~/.propellorrepository using it.
~/.propellor/config.hs, and add a host you want to manage. You can start by not adding any properties, or only a few.
propellor --spin $HOST
- Now you have a simple propellor deployment, but it doesn't do
much to the host yet, besides installing propellor.
~/.propellor/config.hsto configure the host, add some properties to it, and re-run step 6.
Repeat until happy and move on to the next host. :)
- Optionally, set up a centralized git repository
so that multiple hosts can be updated with a simple
git commit -S; git push
- Write some neat new properties and send patches!
