A docker container to generate mDNS CNAME entries for the virtual hosts used by jwilder/nginx-proxy.
The virtual hosts are held in the VIRTUAL_HOST Env Var of the proxied container.
docker pull hardillb/nginx-proxy-avahi-helper
Currently there are AMD64 and ARM64 based builds.
To work this needs the following 2 volumes mounting:
-v /var/run/docker.sock:/tmp/docker.sock
This allows the container to monitor docker
-v /run/dbus/system_bus_socket:/run/dbus/system_bus_socket
And this allows the container to send d-bus commands to the host OS's Avahi daemon
docker run -d -v /var/run/docker.sock:/tmp/docker.sock -v /run/dbus/system_bus_socket:/run/dbus/system_bus_socket hardillb/nginx-proxy-avahi-helper
If you are running on system with AppArmor installed you may get errors about not being able to send d-bus messages. To fix this add
--privileged to the command line.
This is a temp workaround until I can work out a suitable policy to apply.
This uses and borrows heavily from mdns-publisher
