Managing configuration files across multiple servers

Question

Running a Rails application on multiple servers (~20), I want to able to manage the configurartion files (mainly *.yml, but also SSL pem/certs files and other text based) from a single location such that any change to files, or a new file, is added to all servers.

I also want to have this content source controller via git.

Updated are not frequent and I want to keep the app untouched such that data is read from files as it is right now.

What are the available solution for that, is Zookeeper good fit?

Answer 1

I have not used Zookeeper but I believe you should be able to do something like you need with a tool such as Puppet or Chef.
