Description

Installs tilestache running under gunicorn, provides a vagrant environment for iterative testing

• website: https://github.com/mapzen/chef-tilestache.git

Usage

include_recipe 'tilestache'

It's recommended that you use a wrapper cookbook with tilestache. The setup is very simple: a single recipe that does an include_recipe tilestache, and provides a template to be placed in default[:tilestache][:cfg_path].

Supported Platforms

Tested on Ubuntu12.04LTS. You can probably get away with distributions similar to those, but as yet they have not been tested.

Requirements

• Chef >= 11.4
• Vagrant 2

Vagrant Environment

Installation

vagrant plugin install vagrant-berkshelf 
bundle install
berks install
vagrant up
vagrant ssh

What did that just do?

• installed berkshelf, installed our cookbook dependencies, and booted a virtualbox machine
• access the running tilestache instance: via http://localhost:8000

I don't like Vagrant

• well then sir, provision an Ubuntu12.04 LTS system with the provider of your choice, and then bootstrap with chef-solo: knife solo bootstrap root@${host} -r 'recipe[tilestache]'
• and re-cook with the following: knife solo cook root@${host} -r 'recipe[tilestache]'
• alternatively, you can add the tilestache cookbook to your chef server and wrap it as you see fit

Provisos

• only been tested on my laptop!!! (just kidding... mostly)
• for realz, only been tested on Ubuntu12.04LTS
