Bug: Testcontainers in Docker container

method get_container_host_ip(self) in testcontainers/core/container.py

have the following code commented (you drive me crazy) and should be uncommented

    # # check testcontainers itself runs inside docker container
    # if inside_container() and not os.getenv("DOCKER_HOST") and not host.startswith("http://"):
    #     # If newly spawned container's gateway IP address from the docker
    #     # "bridge" network is equal to detected host address, we should use
    #     # container IP address, otherwise fall back to detected host
    #     # address. Even it's inside container, we need to double check,
    #     # because docker host might be set to docker:dind, usually in CI/CD environment
    #     gateway_ip = self.get_docker_client().gateway_ip(self._container.id)

    #     if gateway_ip == host:
    #         return self.get_docker_client().bridge_ip(self._container.id)
    #     return gateway_ip

Commencez dans testcontainers/core/container.py, au niveau de get_container_host_ip(self), et lisez la logique de détection de l’hôte environnante ainsi que la branche Docker-in-Docker commentée. Vérifiez les tests existants pour la résolution de l’hôte du conteneur, puis vérifiez que la branche est active et que le comportement attendu de l’IP de l’hôte ou de la bridge est couvert.
