Understood. Both Traefik and NGinx are reverse proxy apps which allows access from the outside world to your server. Unfortunately, Traefik is not currently offered in the iX application catalog, but NGInx is. With the release of Electric Eel, apps are now handled in Docker containers instead of Kubernetes containers, and you can upload a yaml file for an application.
Like I said, check Nginx Proxy Manager - Configuration Tips (especially if you are stuck at Deploying) for my notes. If you scroll down, you can see some screenshots on how I created the mappings.
Question about the configuring the apps are best asked in the Apps and Virtualization forum. It is possible to upload a yaml file for a custom install, but I haven’t done that yet.
