Chef cookbook - rackbox (v0.1.2)

Setup a Rack-based application server to run Unicorn & Passenger apps.

It performs the following tasks when setup the server:

setup a ruby version manager (now using rbenv).
setup nginx as front-end server.
setup runit service.
setup Unicorn apps (if any).
setup Passenger apps (if any).

Install

To install with Berkshelf, add this into Berksfile:

cookbook 'rackbox'

And overwrite attributes to customize the cookbook.

See also teohm/kitchen-sample for rackbox usage example with chef-solo.

Troubleshooting & Log paths

runit run logs: /etc/sv/{app}/log/main/current
nginx logs: /var/log/nginx/{app}.log
unicorn logs: /home/apps/{app}/current/log/unicorn.stderr.log

Attributes

You should specify the ruby versions to be installed:

node["rackbox"]["ruby"]["versions"] (default: ["1.9.3-p385"]) - ruby versions to be installed.
node["rackbox"]["ruby"]["global_version"] (default: "1.9.3-p385") - set the system-wide ruby version.

To setup unicorn apps, provide a list of unicorn app entries:

node["rackbox"]["apps"]["unicorn"] (default: [])

# Example:
node["rackbox"]["apps"]["unicorn"] = [
  {
    "appname" => "app1",            # app name
    "hostname" => "app1.test.com"   # domain name
  },
  {
    "appname" => "app2",            # app name
    "hostname" => "app2.test.com",  # domain name
    "nginx_config" => {             # overwrite default config:
      ...                           #   node["rackbox"]["default_config"]["nginx"]
    },
    "runit_config" => {             # overwrite default config:
      "rack_env" => "staging"       #   node["rackbox"]["default_config"]["unicorn_runit"]
    }
  }
]

To setup passenger apps, provide a list of passenger app entries:

node["rackbox"]["apps"]["passenger"] (default: [])

# Example:
node["rackbox"]["apps"]["passenger"] = [
  {
    "appname" => "app3",            # app name
    "hostname" => "app3.test.com"   # domain name
  },
  {
    "appname" => "app4",            # app name
    "hostname" => "app4.test.com",  # domain name
    "nginx_config" => {             # overwrite default config:
      ...                           #   node["rackbox"]["default_config"]["nginx"]
    },
    "runit_config" => {             # overwrite default config:
      "rack_env" => "staging"       #   node["rackbox"]["default_config"]["passenger_runit"]
    }
  }
]
