I currently have two environments in which I work: development
locally and production
on Heroku.
I would like to add a staging
environment on Heroku to see that everything goes as expected before pushing the app live to users. Preferably, the staging
environment should have the exact same settings and data as the production
environment.
What are the steps needed to accomplish the above?
Staging environment allows the testers to examine the product on a near-production level in a non-production environment. It offers a platform where the developers can perform an ultimate quality assurance check. This ensures that users get the best quality.
A staging environment (stage) is a nearly exact replica of a production environment for software testing. Staging environments are made to test codes, builds, and updates to ensure quality under a production-like environment before application deployment.
Think of it as a safe space where you can throw everything together and find out how it works. And to ensure your product performs exactly how you expect it to in the real world, you need both a testing and staging environment. The testing environment helps you ensure that each component does its job.
First the predispositions, i like to have my heroku git remotes set up as staging and production so you can easily use git push staging/production to deploy to each one of them. I'll be using that setup to explain how to make a staging env.
config/environments/staging.rb
which you will copy off `config/environments/production.rb'heroku plugins:install git://github.com/ddollar/heroku-config.git
heroku config:pull --remote production
RACK_ENV=staging RAILS_ENV=staging
so it will use the staging environment configuration.heroku fork -a production staging
(those are heroku appnames you want instead of production/staging)You can also read this tutorial, i think i used it to get started with multiple envs on heroku: https://devcenter.heroku.com/articles/multiple-environments#managing-staging-and-production-configurations
