Copiloting Rails

Example Ruby on Rails application deployed to AWS with copilot-cli.

How to

Create a Rails application

rails new copiloting_rails --database=postgresql
cd copiloting_rails

Initialize Copilot application and environments

copilot app init copiloting-rails
copilot env init -n production

You'll want to add more than one environment, but here I'll just create one for simplicity.

Generate secret

secret=$(docker compose run --rm --no-deps web rails secret)
copilot secret init -n SECRET_KEY_BASE --values "production=$secret"

Create the web service

Make sure to create the SECRET_KEY_BASE secret before continuing as the application won't start without it.

copilot svc init -n web -t "Load Balanced Web Service" --dockerfile ./Dockerfile

Then edit copilot/web/manifest.yml and add the following:

secrets:
  SECRET_KEY_BASE: /copilot/${COPILOT_APPLICATION_NAME}/${COPILOT_ENVIRONMENT_NAME}/secrets/SECRET_KEY_BASE

Finally deploy the service

copilot svc deploy -n web -e production
