  | ap-port | Connect to an AP with a specified port. If no AP with that port is present a fallback AP will be used. Available ports are usually 80, 443 and 4070. -- | -- | --

That is the port of Spotify's Access Point you want to connect to, not the port librespot listens on.

I'm trying to run librespot on a specific port.

You can't do this. Librespot doesn't listen on any ports (other than for zeroconf). It connects to a Spotify Access Point server and communicates with other clients via this server.

EDIT: Actually, I can't' remember if this is true. Someone else can correct me here please.

There's --zeroconf-port, which sets the port that librespot listens on for zeroconf, which is probably what @yanover tries to do?

Yes this is the option I was looking for, I missed it in the documentation, thank you !

What is not clear to me is which port my Spotify client will listen on.

If I create a service that listens on my pod's port 4070, which port(s) should be exposed outside of the cluster to my client ?

I found in different place that spotify-connect listen on port TCP and UDP port 57621, is that correct ?
