- A temporary password for the `admin` user will be printed to the container log on startup. Change it immediately to a static one that does not change again.
You can follow parts of [this Youtube tutorial](https://youtu.be/LD8-Qr3B2-o?si=49RQxJ5KRcoETCiQ&t=740) on how to configure most of the arr applications.
**Note**: As all arr containers live within the same Docker network, you can easily reference container names instead of IPs. Docker will resolve the container names automatically to the current docker containers' IP. No need for port mappings or defining your Docker server's IP address. Use Docker networks! The only exception is qbittorrent, which uses the vpn killswitch network of the gluetun container. Here, the gluetun container will expose qbittorrent's web ui on TCP/8080 and the IP address of your docker host server. Setup qbittorrent in all arr-applications using your server's local IP address, on which port 8080 is mapped to.
During the setup of Emby in a web browser (HTTPS via Traefik) you may notice errors in the developer console, which prevent the web page from loading properly.
Those errors occur, if you have configured secure HTTP response headers such as X-Content-Type-Options with the directive "nosniff".
To complete the web-based setup, you either have to temporarely disable the HTTP header or browse the Emby instance without Traefik as reverse proxy.
After the setup was completed, the errors are gone and you can use Emby regularly with Traefik, HTTPS and any X-Content-Type-Options header configuration.
