Since Docker 20.10.6: Error starting userland proxy: listen tcp6

まずスタックトレースから GenericContainer.start() と ResourceReaper.start() をたどり、次にコンテナのポートバインディングが Docker にどのように渡されるかを調べます。IPv6 を無効にした状態で失敗を再現し、文書化されている 0.0.0.0 の回避策と比較します。この CI 環境で、明示的なネットワークインターフェースオプションを指定して Docker テストを正常に開始できれば完了です。

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;
