Question: network_mode: host really required?

[thomas-mc-work]

As the title says. Is there a reason why it's not calling a certain port?

network_mode: host allows caddy to listen on IPv4 AND ipv6 at the same time.

by default docker only listen on ipv4 so this is a workaround in order to have ipv6 reachability without touching the docker configuration.

but this has been discussed to change this behavior: #183

[thomas-mc-work]

What about using the respective directive, from the documentation:

https://docs.docker.com/engine/daemon/ipv6/

It can be enabled in for the the virtual network:

 networks:
   searxng:
     enable_ipv6: true

[unixfox]

That's exactly what I proposed here: #183

[thomas-mc-work]

You're right. Sorry for the confusion.
