Capistrano::Foreman

Capistrano V3 for foreman

WIP

There be dragons, proceed at your own risk.

Installation

Add this line to your application's Gemfile:

gem 'capistrano3-foreman-precogs'

And then execute:

$ bundle

Or install it yourself as:

$ gem install capistrano3-foreman-precogs

Usage

Require in Capfile to use the default task:

require 'capistrano/foreman'

Export Procfile to upstart

This task will be run before deploy:restart as part of Capistrano's default deploy, or can be run in isolation with:

cap production foreman:export

NOTE

In order for foreman to export to upstart your deploy user must have sudoer privileges

Options

Custom ENVIRONMENT variables for foreman (see here).

set :foreman_env,  '/remote/path/to/your.env'         # Default none
