Since Docker 20.10.6: Error starting userland proxy: listen tcp6

Empieza rastreando GenericContainer.start() y ResourceReaper.start() a partir del stack trace y, después, inspecciona cómo se pasan a Docker las vinculaciones de puertos de los contenedores. Reproduce el fallo con IPv6 deshabilitado y compáralo con la solución alternativa documentada de 0.0.0.0. Se considera terminado cuando los tests de Docker pueden iniciarse correctamente en ese entorno de CI con una opción explícita de interfaz de red.

With Docker 20.10.6 docker is failing when ipv6 is disabled.
There seems to be a workaround by explicitly specifying the network interface. For example:

$ docker run --rm -d -p 0.0.0.0:8080:80 nginx:latest

Is there a possibility to specify the network inteface using the GenericContainer? I cannot find anything in the API. Any workaround is appreciated, since all docker tests are failing due to this issue and it is no possible to enable ipv6 on our CI environment.

The following is the actual error that occurs during running a testcontainer;
