Avahi multicast DNS / mDNS / Zeroconf Docker image (auto-updated)
10K+
The image is maintained and published here: https://github.com/ensody/avahi
This is a simple Avahi Docker image.
The CI automatically checks for updates (e.g. security fixes) several times daily and publishes a new image only when necessary. So, this image could be used with podman-auto-update or Watchtower.
There's a default avahi-daemon.conf.
Usually you can just add one or more service definitions to /etc/avahi/services.
For more customization you can add your own /etc/avahi/avahi-daemon.conf or override the whole /etc/avahi folder.
This will add a Samba service for auto-discovery on Linux and macOS, including Time Machine support.
