Minimal boiler plate to create a dockerized Ruby on Rails 7 application.
git clone https://github.com/betogrun/prelude.git your_application
# or
git clone [email protected]:betogrun/prelude.git your_application
Change the application name on Dockerfile
WORKDIR /usr/src/your_applicationChange the application name on docker-compose.yml
web:
build: .
entrypoint: ./entrypoint-dev.sh
command: bash -c "bundle exec foreman start -f Procfile.dev -p 3000"
tty: true
volumes:
- .:/usr/src/your_application
Generate an application with Postgres database, esbuild and Tailwind CSS. Feel free to change the options, but keep in mind the next steps may be affected.
docker-compose run --rm --no-deps web bundle exec rails new . --force -d postgresql -j esbuild --css tailwind
docker-compose run --rm web bundle add foreman --group "development, test"
Change the files ownership if you are using Linux.
sudo chown -R $USER:$USER .
Add the following content to config/database.yml default entry.
default: &default
adapter: postgresql
encoding: unicode
host: <%= ENV.fetch("DATABASE_HOST") %>
username: <%= ENV.fetch("DATABASE_USER") %>
password: <%= ENV.fetch("DATABASE_PASSWORD") %>
# For details on connection pooling, see Rails configuration guide
# https://guides.rubyonrails.org/configuring.html#database-pooling
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>docker-compose run --rm web bundle exec rails db:create
Add the following content to package.json
"scripts": {
"build": "esbuild app/javascript/*.* --bundle --sourcemap --outdir=app/assets/builds",
"build:css": "tailwindcss -i ./app/assets/stylesheets/application.tailwind.css -o ./app/assets/builds/application.css --minify"
}
$ docker-compose up
Get the id for the web container
