This README would normally document whatever steps are necessary to get the application up and running.

Things you may want to cover:

• Ruby version

• System dependencies

• Configuration

We have a docker-compose file set up to allow smoother local development. The compose structure includes services needed for running the stocks app locally, with preconfigured connections.

At present, these services are: postgres, redis, and the rails application.

To start the application, run docker compose up. Adding -d will free your terminal after the service boots. After the application starts, the site can be accessed at http://localhost:3000.

To set up the database the first time run, docker compose run --rm stocks bin/rails db:setup

The docker entrypoint takes care of installing updated gems, and running any pending database migrations before starting the rails application. Any gem or configuration changes can be applied by restarting the application server: docker compose restart stocks

To run rails commands, such as rails generate ..., it is easiest to step into a console:

$ docker compose run --rm stocks bin/rails generate ....

If a console is needed for multiple commands, you can launch a shell in a running the container:

$ docker compose run --rm stocks bash

To run RSpec tests in the container:

docker compose run --rm stocks rspec

Or a specific file/directory may be specified to narrow the scope:

docker compose run --rm stocks rspec spec/features
