A container running its own avahi-daemon collides with the host's on :5353. Instead publish to the host avahi over its mounted D-Bus socket using avahi-tools (avahi-publish). Needs apparmor=unconfined (docker-default blocks the D-Bus publish). Documented host prereqs incl. allow-interfaces for multi-bridge hosts. Tested: publish reaches host avahi and registers the names; on hosts with many docker bridges avahi self-collides until restricted to the LAN interface.
