# Rails 6 on Docker demo application
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](https://github.com/ryanwi/rails7-on-docker)
## Requirements
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
```
## Initial setup
```
cp .env.example .env
docker compose build
docker compose run --rm web bin/rails db:setup
```
## Running the Rails app
```
docker compose up
```
## Running the Rails console
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
```
## Running tests
```
docker compose run --rm web bundle exec rspec
```
## Updating gems
```
docker compose run --rm web bundle update
docker compose up --build
```
## Updating Yarn packages
```
docker compose run --rm web yarn upgrade
docker compose up --build
```
## Webpacker retirement
Many Rails 6 apps will be or were created with the Webpacker gem. On January 19, 2022, [Webpacker announed its retirement](https://github.com/rails/webpacker#webpacker-has-been-retired-). As a result, it has been replaced in this repo with jsbundling-rails based on the recommendation in the announcement.
