Angora

Dependencies

• Docker https://docs.docker.com
• Docker Compose https://docs.docker.com/compose/

Running

Run the below code:

docker-compose up web

Setup

You need execute migrations to neo4j and populate database with default test data to see the system works.

docker-compose run web rails neo4j:migrate RAILS_ENV=development
docker-compose run web rake db:seed

Testing

Run the below code:

docker-compose run web rails test

Debugging with byebug inside the Docker

app:
  tty: true
  stdin_open: true

This also makes it possible to after the containers are up do docker attach angorah_web_1 which seems to work fine.
