Home Assistant on Docker Compose without Network Mode Host

Installation
1

Hi everyone,

I’m running Home Assistant using Docker Compose, and for security reasons, I prefer not to enable the network_mode: host option. However, I’ve encountered a problem where many integrations, such as Apple TV, don’t work because broadcast packets aren’t received in this setup.

From my research, it seems that the root cause is the lack of proper handling for mDNS broadcasts within this configuration. A possible solution I found is to set up an mDNS repeater to bridge this gap, but I’m not sure how to proceed with this.

Could anyone provide specific guidance or examples of how to set up an mDNS repeater in conjunction with Docker Compose? Alternatively, are there other secure solutions that would allow me to use these integrations without relying on network_mode: host?

Thanks in advance for your help!

macvlan allows mdns

you must create macvlan network then attach your container to the network

To add some detail to the previous answer, macvlan gives the container it’s own virtual interface with it’s own MAC address, Just as if it were a separate device on your network.

Details on my setup here;

This setup worked fine on regular and raspberry flavored Debian 10/11, and is currently running on my Unraid server with only a couple of small tweaks.

Cheers.
