Working Rails 6.1 demo application with PostgreSQL, Docker, jsbundling-rails (with Webpack), and GitHub Actions
This app demonstrates Rails 6 with PostgreSQL and Webpack (with jsbundling-rails), all running in Docker.
NOTE: There is also an example Rails 7 application working in Docker without Webpack or node.js
Please ensure you are using Docker Compose V2. This project relies on the docker compose
command, not the previous docker-compose
standalone program.
https://docs.docker.com/compose/#compose-v2-and-the-new-docker-compose-command
Check your docker compose version with:
% docker compose version
Docker Compose version v2.10.2
cp .env.example .env
docker compose build
docker compose run --rm web bin/rails db:setup
docker compose up
When the app is already running with docker-compose
up, attach to the container:
docker compose exec web bin/rails c
When no container running yet, start up a new one:
docker compose run --rm web bin/rails c
docker compose run --rm web bundle exec rspec
docker compose run --rm web bundle update
docker compose up --build
docker compose run --rm web yarn upgrade
docker compose up --build
Many Rails 6 apps will be or were created with the Webpacker gem. On January 19, 2022, Webpacker announed its retirement. As a result, it has been replaced in this repo with jsbundling-rails based on the recommendation in the announcement.
