Rails Starter

This repo is a new rails installation in a docker container.

The application consists of

• Rails 5.1
• Rspec
• Guard
• Postgres database
• Support for background job processors through a Redis image

Prerequisites

You must have a working docker environment with docker-compose support. If you need help getting that set up, go here

Setup

After cloning the repo...

docker-compose build
docker-compose run --rm web bin/setup

Once you're all set up, nuke this git history and start fresh:

rm -rf .git
git init

This allows you to add your own remote and go from there. I hope this makes getting started with Rails in docker a little easier.

Usage

run the app

docker-compose up web

console

  docker-compose run --rm web rails c

generate a new model

docker-compose run --rm web rails g model model_name attributes:text

migrate

docker-compose run --rm web rake db:migrate

run guard

docker-compose run --rm web guard

run specs

docker-compose run --rm web rspec

Nib

Nib is a fantastic tool for ruby/rails development in a docker-compose environment

the above commands would be:

nib up web
nib console web
nib run web rails g model model_name attributes:text
nib rake web db:migrate
nib run web guard
nib run web rspec

Additional benefits include

• shell history inside a container (!!)
• irb/pry history inside a console (!!)
