# Rails 7 on Docker demo application
This app demonstrates Rails 7 with PostgreSQL, import maps, turbo, stimulus and hotwire, all running in Docker.
**NOTE:** There are also examples Rails 8 and Rails 6 applications working in Docker
* [Rails 8 Applicaiton Docker Template](https://github.com/ryanwi/rails8-on-docker)
* [Rails 7 Applicaiton Docker Template](https://github.com/ryanwi/rails7-on-docker)
* [Rails 6 Application Docker Template](https://github.com/ryanwi/rails-on-docker)
## Features
* Rails 7
* Ruby 3.3
* Dockerfile and Docker Compose configuration
* PostgreSQL database
* Redis
* GitHub Actions for
* tests
* Rubocop for linting
* Security checks with [Brakeman](https://github.com/presidentbeef/brakeman) and [bundler-audit](https://github.com/rubysec/bundler-audit)
* Building and testing of a production Docker image
* Dependabot for automated updates
## 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 bin/rspec
```
## Updating gems
```
docker compose run --rm web bundle update
docker compose up --build
```
## Production build
(adjust tags as needed)
### with [BuildKit](https://docs.docker.com/build/buildkit/)
```
DOCKER_BUILDKIT=1 docker build --tag rails-on-docker --load .
```
Test the image can be used and Rails starts up, use a fake key for testing purposes only:
```
docker run --rm --env SECRET_KEY_BASE=dummy rails-on-docker
```
### With legacy builder (no BuildKit)
```
docker build --tag rails-on-docker .
```
Test the image can be used and Rails starts up, use a fake key for testing purposes only:
```
docker run --rm --env SECRET_KEY_BASE=dummy rails-on-docker
```
## Deployment
This app can be hosted wherever Ruby is supported and PostgreSQL databases can be provisioned.
#### Render
[](https://render.com/deploy?repo=https://github.com/ryanwi/rails7-on-docker)
NOTE: You will need to generate a production secret with `bin/rails secret` and set it as the `SECRET_KEY_BASE` environment variable.
