Bootstrap a dockerized rails app

Script to quickly bootstrap a new dockerized rails app.

The ansible playbook provisions a vagrant box with a dockerized rails app with nginx, puma, redis, postgres and sidekiq.

Requirements

Vagrant

Ansible

Getting started

Clone the repo

git clone https:/otaviomedeiros/ansible-docker-rails.git

cd ansible-docker-rails

Run vagrant box

vagrant up

This command will provision the vm and bootstrap a new dockerized rails app.

Now ssh into the machine

vagrant ssh

Cd into the app folder

cd /vagrant/railsapp

Run the app

docker-compose up

To create the database

docker-compose run app rake db:create

The docker-compose.yml is described bellow
