When I did some work on Puppet, I found the concept of the file server hella confusing as I had come from Chef. I also found the documentation on where to put template files and file-files confusing. (You should put templates in X dir but Puppet will look for them in Y dir first, WAT?)
In Chef, when you have a file or template associated with a cookbook, you can simply drop them in <cookbook>/templates/default and <cookbook>/files/default. There are more complex use cases as well, however, 99% of the time the default directory is good enough for what you want.
When referencing the files in recipes, you use the "source" attribute and chef will figure out where the file is starting by looking in those default cookbook directories.
cookbook_file "/etc/blah/blah.config" do
source "blah.config"
end
This is all in the resource reference page, but I figured it was worth talking about in more detail if you are used to Puppet and a file server. Chef and Puppet seem to come at this from odd directions if you are used to one over the other. I actually started a Puppet for Chef users series on my blog and was going to talk about files and templates, but figuring it out for Puppet kind of gave me some ragefaces. And by the time I was over it, I was working on something else. I may revisit.

Still trying to get bootstrapped myself :) Too bad there's know "knife-person bootstrap"...

- create a symlink to it in /etc/nginx/sites-enabled
- disable the /etc/nginx/sites-enabled/default symlink
You can drop a file in /etc/nginx/sites-available, and then use
nginx_site "name-of-your-file-in-sites-available" doenable trueend
to have Chef enable the site for you (reloading nginx's configuration as appropriate)
Or, to just replace the default config block directly and save the hassle of mucking around with multiple files.
What's the best way to go about this?
Recent versions of the nginx cookbook have an attribute node["nginx"]["default_site_enabled"] which you can set to false to disable the default site. You can then use the above recommendation to institute your own default site. You can set this from a recipe, role, environment, etc.
