Distinct server names or routes to applications on UAT

[pgwillia]

Distinct server names or routes to applications instead of port ‘x’ is Jupiter, port ‘y’ is avalon, etc. Personally, I find names easier to remember than numbers. If the applications are containerised, a reverse proxy could handle the routing. Envoy or Traefik?

nginx-proxy looks to be another option. It can handle multiple virtual hosts and has thought about SSL using let's encrypt. There's an example for what this could look like as a docker-compose

Here's an article which describes Traefik where you add Traefik labels

version: "3"services:
  calibre:
    image: linuxserver/calibre-web
    container_name: calibre
    restart: unless-stopped
    ports:
      - "9083:8083"
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.cal.rule=Host(`books.mydomain.com`)"
      - "traefik.http.routers.cal.entrypoints=web"
      - "traefik.http.services.cal.loadbalancer.server.port=9083"

Wendy added a wildcard dns entry of *.uat.library.ualberta.ca will resolve to uat.serv01.library.ualberta.ca.
