Docker container: connection refused

Since https://unboundtest.com/ currently returns 502 Bad Gateway, I wanted to run the current version in my network.
I cloned the project, built and started the current version from main branch (tag v0.1.0) using Docker.
Unfortunately, when testing a domain, the following logs are printed:

Query results for CAA example.com
----- Unbound logs -----
Dec 29 18:08:31 unbound[38:0] debug: creating udp6 socket ::1 1053
Dec 29 18:08:31 unbound[38:0] error: can't bind socket: Address not available for ::1 port 1053 (len 28)

Error running query: read udp 127.0.0.1:47050->127.0.0.1:1053: read: connection refused

The last line suggests that unbound probably won't start with the current Dockerfile.

Okay, i did some research. In my setup IPv6 is not activated and used.
This is the reason why unbound stops working instead of skipping IPv6 support.

When i disable IPv6 support in the unbound.conf and rebuilt the image then the service is running as expected.

I could close the issue or let it open for a feature request:
Make IPv6 optional :)
