• Ruby 3.0.0
• Rails 6.1
• Needs mongo and redis

1. Make sure mongo and redis are running
2. bin/rails test

docker-compose up --build will set up 5 containers:

1. mongo
2. redis
3. web - the application running in development mode
4. checker - a small container that makes a GET /healthiness request every 2 seconds
5. tests - runs the test suite once

The application is shipped via a Docker image and is configured purely through environment variables. Here they are:

MONGODB_HOSTS=localhost:27017

REDIS_HOST=localhost
REDIS_DEFAULT_DB=0
REDIS_USER
REDIS_PASSWORD
