About

Capistrano PostgreSQL plugin abstracts and speeds up common administration tasks for PostgreSQL when deploying rails apps.

Here are the specific things this plugin does for your capistrano deployment process:

  • creates a new PostgreSQL database and database user on the server
  • generates and populates database.yml file on all release nodes (no need to ssh to the server and do this manually!)
  • zero-config
  • support for multi-server setup: separate db and app nodes (from version 4.0)

Note: gem version 4 introduces some breaking changes. If you installed gem version 3 or below you might want to follow the upgrade instructions.

Installation

Put the following in your application's Gemfile:

group :development do
  gem 'capistrano', '~> 3.2.0'
  gem 'capistrano-postgresql', '~> 4.2.0'
end

Then:

$ bundle install

Usage

If you're deploying a standard rails app, all you need to do is put the following in Capfile file:

require 'capistrano/postgresql'

Make sure the deploy_to path exists and has the right privileges on the server (i.e. /var/www/myapp).
Or just install capistrano-safe-deploy-to plugin and don't think about it.

To setup the server(s), run:

$ bundle exec cap production setup

Gotchas

Be sure to remove config/database.yml from your application's version control.
