This is a database-less rails application meant for deployment into kubernetes clusters for pipeline evaluation.
The app can be deployed in two modes (frontend and backend) which is selected using config/mode.yml
Frontend mode exposes the /guests endpoint which makes a request to the backend found at the location specified in config/backend.yml and then presents the results in HTML.
Backend mode exposes /guest_from_db endpoint which responds with some JSON representing a list of guests.
Dockerfile builds the app and exposes the endpoints on port 9000 in the resulting image.
A 200 response from the /health endpoint indicates the app is healthy and able to respond to requests independent of health status of external dependencies.
A 200 response from the /deep_health endpoint indicates that the app and all external dependencies are healthy. The results of each check are listed in a table in the response.
