Ruby / Rails

Prerequisites

• Dependencies managed by bundler, via Gemfile

Optional configuration

• Specify a web process with a Procfile

Add a database

Options for AWS-managed database add-ons include RDS MySQL and Postgres.

By default the connection and authnetication details are sent to the app via the environment variable DATABASE_URL, which Rails handles automatically by default.

Sqlite

To use Sqlite you can add-on an EFS volume, mounted on /workspace/sqlite and then point to it by setting the env var:

$ tapit set variable DATABASE_URL sqlite3:///workspace/sqlite/production.db

Set environment variables

$ tapit set variable SECRET_KEY_BASE `bundle exec rails secret` secret=yes

Migrate database

To run commands interactively at a shell prompt:

$ tapit run bash

To create a background task (without console interactions, ideal for scripting) for DB migration:

$ tapit create task 'bundle exec rake db:setup'`

$ tapit create task 'bundle exec rake db:migrate'`
