Simple Staging/Test Environment with Heroku – Ruby on Rails

Hey everyone,

This is just a quick guide on how to create a test/staging environment with Heroku.

-- Create staging environment
heroku create --remote staging
 
-- Push to staging app
heroku push staging master
 
-- Run rake db:migrate on staging app
heroku run rake db:migrate --remote staging
 
-- Add pgbackups add ons
heroku addons:add pgbackups --remote staging
heroku addons:add pgbackups --remote heroku
 
-- Create backup of production data
heroku pgbackups:capture --remote heroku
 
-- Copy to staging environemnt
heroku pgbackups:restore DATABASE `heroku pgbackups:url --remote heroku` --remote staging
 
-- Create a new config file called staging.rb (/config/environments/staging.rb)
 
-- Add environment variables
heroku config:add RACK_EVN=staging RAILS_ENV=staging --remote staging
 
-- Ready to go !

For those of you using git branches etc, the following may come in handy as well:

-- Create local development branch
git branch development
 
-- Switch to dev branch
git checkout development
 
-- Make your changes and commit them
git init
git add .
git commit -m "My changes"
 
-- Push to staging environment (local development branch to staging environment master branch)
git push staging development:master
