+# Rails 5 Docker boilerplate
+
+Boilerplate for Rails projects using Docker.
+
+
+## Building the project
+
+Run the following command to create a new Rails project scaffold with a postgres database.
+
+```bash
+docker-compose run web rails new . --force --database=postgresql --skip-bundle
+```
+
+In order to have a JavaScript runtime you have to uncomment this line in your Gemfile.
+```
+gem 'therubyracer', platforms: :ruby
+```
+
+After that build the project in order to install new Gems.
+
+```bash
+docker-compose build
+```
+
+## Database
+
+Use the following configuration for your **development** and **test** databases.
+
+```yaml
+development: &default
+  adapter: postgresql
+  encoding: unicode
+  database: postgres
+  pool: 5
+  username: postgres
+  password:
+  host: db
+
+test:
+  <<: *default
+  database: myapp_test
+```
+
+After this you can run the project and get ready to create the database.
+
+```bash
+$ docker-compose up
+```
+
+Run this command to create the database.
+
+```bash
+$ docker-compose run web rake db:create
+```
+
+## Running
+
+At this point your application must be running on localhost on port 3000, so head over to it and take a look!
+
+[http://localhost:3000](http://localhost:3000)
