You could use the fog gem to provision an instance, but when the instance is available (via ssh), you'd have to have something run the bootstrap command to tell the node to provision with chef.

This is a work-in-progress project I have to rewrite the bootstrapping process for knife. The code should be a good reference:

This is what we do at EA, more-or-less. We poke the API of the cloud in  
question to do some peripheral configuration (security groups, EIP, etc.),  
poke the API to create a box, spin until the box is up, spin again until  
the IP assignment is all done, and then bootstrap the box via ssh.

We do all of this from within an asynchronous job in Rails, in pure ruby  
(no shell-out) by re-using the classes the chef and knife gems provide,  
alongside some custom stuff to talk to RightScale.

So, to give you an answer: you need to get inside the knife and Chef code,  
understand how they do what they do, and then re-use their classes as  
appropriate in your own code. Chef:🔪:Bootstrap in  
./lib/chef/knife/bootstrap.rb (in your exploded gem) might be a good place  
to start. In simple terms, you need an appropriately populated Chef::Config  
and then you need to do something like:

bootstrap = Chef:🔪:Bootstrap.new  
...  
bootstrap.run
