mDNS resolution from within a container in rootless mode

Docker Engine General
1

Hi,

Here is the setup, got 2 machines - m1 and m2 inside a LAN.
Both are able to see each other via ip (of course) and both have mdns configured so that ping m1.local is successful from m2 and ping m2.local is successful from m1.
So mDNS is functional at host level.

Now on m2 docker engine is installed and run in rootless mode.
I want from a container on m2, be able to ping m1.local.
Is there any way to achieve that without installing anything inside images?

If you run the container with host network it should hypothetical just work.

Otherwise you can manually supply a DNS entry to your container (--add-host) or use a mDNS relay/proxy.
