Development

To provide a consistent experience on every system, docker and docker-compose is used during development and production.

Using Docker and Make (recommended)

Linux/Unix

1. Install Docker and Docker Compose

2. Start the development server

   make dev

   This will start a development server on http://localhost:3000

3. Seed the database.

   make dev-seed

   The development setup uses an SQLite 3 database, which can be found under /db/development.sqlite3

Windows

1. Install WSL (Windows Subsystem for Linux)
2. Follow the instructions for Linux/Unix above

Directly on your system

1. Install asdf
2. Install dependencies: asdf install
3. Install gems: bundle install
4. Migrate the db using bundle exec rails db:migrate
5. Seed the db using bundle exec rails db:seed
6. Start Tap by running bundle exec rails s

Production

You can generate a production docker image using:

make build

The image will be tagged under tap:latest

FAQ

Can I use Tap for development without setting up Tab?

Tap does not sync with Tab when in development mode. The user's balance is mocked by Ƶ12.34 instead.

How do I login as the "Koelkast" user?

In development, you can login as Koelkast using the link: https://localhost:3000/sign_in?token=token

I get a "mismatching_redirect_uri" error when trying to login

The Zeus authentication provider has a pre-configured list of hosts that are allowed to use the login. http://localhost:3000 is on this list and should be used for development.

Docker image build is stuck on "Fetching gems..." or another command

If you are connected to the **`eduroam`** network, Docker build will not have access to the internet. This is because eduroam and docker use the same IP range, which causes conflicts. To solve this you can [reconfigure Docker to use a different IP range](https://support.skyformation.com/hc/en-us/articles/360009195759-How-To-Change-the-Docker-IP-address-space). A recommended range can be `172.31.248.0/21` which is rarely used by other networks.

There are no transactions going from Tap to Tab

The delay job may not be running. You can start it using:

sudo -u tap RAILS_ENV=production /home/tap/production/current/bin/delayed_job start
