ruby on rails 6 docker-compose skeleton

This is a small skeleton for kick starting a new ruby on rails 6 application based on yarn, postgreSQL and ruby on rails inside a docker-compose environment.

The basic rails project has been generated with: rails new rails-docker-compose-skeleton -d postgresql

tech specs

• ruby 2.7.1
• rails 6.0.3.2
• postgreSQL 10.5

usage

# clone this repository
git clone git@github.com:Loumaris/ruby-on-rails-6-docker-compose-skeleton.git <project-name>

# go into the new project and remove the git
cd <project-name>
rm -rf .git

# create a new git tracking
git init
git add .
git commit -m "init commit"

# create a new `/config/master.key`

# build and run docker-compose
docker-compose build

# create db
docker-compose run rails-app rails db:create

# run migrations
docker-compose run rails-app rails db:migrate

# start rails
docker-compose up

# access the rails container during the "uptime"
docker-compose exec rails-app bash

That's it ;-)
