Docker image for the Avahi mDNS/DNS-SD daemon. Built on Alpine Linux to make the image as small as possible. Highly configurable through environment variables to support most usecases which need an Avahi Daemon.
Basic usage consists of running the docker container with the appropriate environment variables and volumes to achieve your desired behaviour.
docker run robostlund/avahi
Environment variables are made available for all of the options of avahi-daemon.conf. The variable names are in the format <SECTION>_<OPTION> where <SECTION> is the capitalised section name from the configuration file and <OPTION> is the capitalised option name with - replaced by _.

If you find an option you require is missing, report this or make a PR adding that feature.
This sections contains several example usages for the. If you use this container for a common scenrio or if any of the examples can be improved, please let me know the configurtion you have used so that I can improve this documentation.
To reflect mDNS broadcasts between two docker networks (net1 and net2 in the example given) the reflector should be enabled by setting REFLECTOR_ENABLE_REFLECTOR=yes.
# Create a container named mdns-reflector attached to net1
docker run -d --name=mdns-reflector \
--network net1 \
-e REFLECTOR_ENABLE_REFLECTOR=yes \
robostlund/avahi
# Attach the container to the net2 network
docker network connect net2 mdns-reflector
