Evalutating Chef for ec2 management


#1

I’m brand new to chef and looking at it as a possible solution for
configuring ec2 instances. The project I am working on is a job scheduler
that uses ec2 nodes. It’s designed to start up and configure ec2 nodes,
then hand out jobs to the running instances, monitor them, start/stop new
servers based on various conditions, etc… Similar to the Condor scheduler
but all in ruby/rails.

One of the main goals is to be able to use any ami, which means the system
has to be able to configure a new instance from the ground up when it
boots. So far I’ve been designing around using Capistrano + custom tasks.
Creating a bunch of rake tasks works fine, but something like Chef could
help standardize things more. Would Chef solo be a good fit here? Could I
push out recipes to a new instance with capistrano and run them without
having to use a Chef server?

Hi Chris. Welcome to the list.

Chef-solo will work fine in this situation. You could even pass a url
to chef-solo instead of having to push the recipes to the ami before
running chef-solo.

If you need something to install chef-solo on the ami I wrote a
sprinkle script that uses ssh to install chef:

Thanks, that looks simpler then pushing out recipies with capistrano.
