# 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 is also an example Rails 6 application working in Docker with Webpacker](https://github.com/ryanwi/rails-on-docker)
|
|
|
|
|
|
## Initial setup
|
|
```
|
|
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
|
|
```
