[Help Requested] Utilising Unraid Avahi for Docker Apps (like Homebridge, scrypted)

[shanelord]

Hi,

 

I'm trying to utilise the underlying avahi-daemon and dbus services for scrypted. I'm using the scrypted app from Unraid apps.

 

If I apply everything I think I need to (see below), I get this error in the scrypted homekit log:

The selected advertiser, "avahi", isn't available on this platform. Reverting to "bonjour-hap"

 

I've pulled everything I think that scrypted docker-compose states it needs out of it and applied it to the services, volumes and security_opt sections, which I've added to my config:
 

# Avahi can be used for network discovery by passing in the host daemon
# or running the daemon inside the container. Choose one or the other.
# Uncomment next line to run avahi-daemon inside the container.
# See volumes and security_opt section below to use the host daemon.
# - SCRYPTED_DOCKER_AVAHI=true


# - /var/run/dbus:/var/run/dbus
# - /var/run/avahi-daemon/socket:/var/run/avahi-daemon/socket


# Uncomment the following lines to use Avahi daemon from the host

# Without this, AppArmor will block the container's attempt to talk to Avahi via dbus
# security_opt:
#     - apparmor:unconfined

 

1. I added the variable SCRYPTED_DOCKER_AVAHI=true to the app config

2. I added the volumes "/var/run/dbus" and "/var/run/avahi-daemon/socket" as extra volume maps

3. I've put "--security-opt apparmor=unconfined" in the extra parameters field

4. I set the container to "Privileged" mode

 

In the container log, I see this:

 

Starting Avahi daemon...
Found user 'avahi' (UID 105) and group 'avahi' (GID 106).
Successfully dropped root privileges.
avahi-daemon 0.8 starting up.
bind(): Address already in use
avahi-daemon 0.8 exiting.
Starting dbus...
dbus-daemon[839]: Failed to start message bus: The pid file "/run/dbus/pid" exists, if the message bus is not running, remove this file

 

Any ideas?

 

Thanks,

Shane.

I guess (a) no-one that has done this wants to share how, (b) no-one else has done this or (c) no-one wants to do it or they don't have time to discuss?

 

I'm hoping an unraid dev could assist - ideally it would be good to only have one mdns solution running to avoid conflicts etc.
