Utilizing a cups/avahi stack in the default balenalib/raspberrypi3-debian image – unable to see the AirPrint service even though it’s configured correctly.
Set up vanilla Raspberry Pi 3 with Raspbian and installed the same packages used for the stack above, and am able to see the AirPrint service from other iOS devices on the WLAN.
I think the breakdown is something to do with mDNS protocols within the container. Verified that building with a custom docker-compose.yml with the
network-mode: host does not help.
