Upstream apps

• Creates capistrano directory structure for an app
• Creates an nginx vhost configured as an upstream server
• If a rack app is detected, creates a unicorn config and upstart script to run the app.

Usage

Create an apps data bag

Create a data bag item for each app:

{
  "id": "app1",
  "unicorn_port": "8001",

  "server_roles" : [ "appserver" ],

  "production": {
    "domains": [
      "example.com",
      "origin.example.com"
    ]
  },

  "staging": {
    "domains": [
      "origin-staging.example.com",
      "staging.example.com"
    ]
  },

  "dev": {
    "domains": [
      "origin-dev.example.com",
      "dev.example.com"
    ]
  }
}

Domains

production, staging, and dev correspond to chef environents. So if the recipe is running on a node who's environment is staging, the recipe will insert those domains into the nginx vhost.

Server Roles

Also, the app will only be installed on nodes that have a role listed in the server_roles array. If server_roles is missing, the app will be installed by default.
