Overview

Nginx acts as a reverse proxy in front of all CEDAR microservices, frontends, and Keycloak.

As such, each request to CEDAR arrives to nginx on the standard 443 https port. Based on the subdomain in the request, nginx will forward the request to one of the components. Nginx talks on plain http with all the microservices and the frontends. Nginx connects to Keycloak using https.

List of services behind nginx

This table summarizes the services that are proxied by nginx. The microservices are ordered in increasing port number order, which shows the evolution of CEDAR.

The frontend is delivered differently during development than on production.
