Install avahi-daemon into an Alpine Linux Container

docker-ubu-avahi

Installs avahi-daemon into an Ubuntu Linux container

Description

Avahi is a free zero-configuration networking (zeroconf) implementation, including a system for multicast DNS/DNS-SD service discovery

http://www.avahi.org/

Usage

docker create --name=avahi-daemon  \
  -v /etc/localtime:/etc/localtime:ro \
  -v /var/run/dbus:/var/run/dbus \
  -e DOCKUID=<UID default:106> \
  -e DOCKGID=<GID default:111> \
     digrouz/docker-ubu-avahi

Environment Variables

When you start the avahi image, you can adjust the configuration of the avahi instance by passing one or more environment variables on the docker run command line.

DOCKUID

This variable is not mandatory and specifies the user id that will be set to run the application. It has default value 111.

DOCKGID

This variable is not mandatory and specifies the group id that will be set to run the application. It has default value 106.

Notes

• The docker entrypoint will upgrade operating system at each startup.
• It is assumed that the host is running the dbus daemon and share the socket through /var/run/dbus with this container. This is a requirement to have mdns support.

docker-ubu-avahi's Issues

Doesn't work on synology

Just to save anyone else the trouble of trying this, I have been unable to get this to work on a Synology DS918+, despite the host running dbus:

avahi-daemon 0.6.32-rc starting up.
dbus_bus_get_private(): Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
WARNING: Failed to contact D-Bus daemon.
avahi-daemon 0.6.32-rc exiting.
