dcchambers / rails-docker-launchpad

A mirror of our rails 5 docker :whale: containerized app template ("launchpad" :rocket:) repo from our Enterprise GH.

rails-docker-launchpad

A launchpad 🚀 to get you started with a new containerized 🐳 rails 5 app!

How to Use This

This repo contains a Dockerfile and docker-compose.yml file to get you started with a pretty basic rails dev environment running in a docker container.

• It will create a new docker image with Ruby, Rails, and NodeJS.
• It will create a docker image with a postgres database.
• It will start both containers and link them in a docker network.

---

• Fork (or clone) this repository (or download the ZIP).
• Run docker-compose up --build -d
• Run docker-compose run <app name> rails new . --force --database=postresql
• Files created by docker are owned by root, so you'll probably have to adjust the file permissions or ownership.
  • sudo chown -R $USER:$USER . should solve the problem.
  • You might have to make the files in the database directory (/tmp/db by default) owned by user postres or change the permissions.
• This generates a new Gemfile. You'll want to run docker-compose build again.
• Replace the contents of config/database.yml with the following:

default: &default
  adapter: postgresql
  encoding: unicode
  host: db
  username: postgres
  password:
  pool: 5

development:
  <<: *default
  database: myapp_development


test:
  <<: *default
  database: myapp_testdefault: &default   

• Run docker-compose up again.
• Create the database. Run docker-compose run app rake db:create
• Rails should now serve up your app at http://localhost:3000
