Dumbwaiter hoists your Rails application up to OpsWorks and ratchets deployment information back down.
Before Scalarium became OpsWorks, they maintained a gem that did the sorts of functions described here. Like Heroku Toolbelt, the Scalarium gem offered users a very basic workflow experience: upload and run Chef recipes, execute commands remotely and watch their output.
Dumbwaiter prescribes a very specific OpsWorks-centric workflow with the same feeling of the Scalarium gem's CLI:
- Create OpsWorks stacks, layers and instances via YAML files
- Assign a stack's custom Chef cookbooks as a custom GitHub repo
- Create an application corresponding to a GitHub repo
- Run versioned deployments, rollbacks and one-off recipes
Dumbwaiter only deals with OpsWorks workflow, excluding:
- Standing up VPCs
- Running CloudFormation templates
- One-off bash-level commands(^) and log tailing
^ Making a cookbook to run one-off commands is totally not unheard-of.
Add this line to your application's Gemfile:
gem 'dumbwaiter'
And then execute:
$ bundle
Or install it yourself as:
$ gem install dumbwaiter
Deploy the "cinnamon" branch of the "syrup" application to the "Pancake" stack:
