Testcontainers work as expected, fail to map Docker port when run with pytest in VS Code

Describe the bug
I copied this code from the python-kafka tests in this repo.
I am able to run it successfully as a script. However, when I run in pytest, the docker container doesn't even start because it can't map to a port.

This behavior only happens when I run pytest.

The error code is as follows:

_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

self = <testcontainers.core.docker_client.DockerClient object at 0x0000016333B4DE90>
container_id = '0100dda1fb4811efbdf5743faf5208c2113f7952824e04799df9c3b497bd9864'
port = 9093

    def port(self, container_id, port):
        port_mappings = self.client.api.port(container_id, port)
        if not port_mappings:
>           raise RuntimeError(f'port mapping for container {container_id} and port {port} is not '
                               'available')
E           RuntimeError: port mapping for container 0100dda1fb4811efbdf5743faf5208c2113f7952824e04799df9c3b497bd9864 and port 9093 is not available

I believe this is a windows issue as I had to add os.environ['TC_HOST'] = 'localhost' because Windows has issues connecting to the localnpipe named pipe.

To Reproduce

from kafka import KafkaConsumer, KafkaProducer, TopicPartition
from testcontainers.kafka import KafkaContainer
import os

def test_kafka_confluent_7_1_3():
    kafka_container = KafkaContainer("confluentinc/cp-kafka:7.1.3")
    # set the advertised listeners to be the container's IP address
    with kafka_container as container:
        container.get_bootstrap_server()
        produce_and_consume_kafka_message(container)

def produce_and_consume_kafka_message(container):
    topic = 'test-topic'
    bootstrap_server = container.get_bootstrap_server()

    producer = KafkaProducer(bootstrap_servers=[bootstrap_server])
    producer.send(topic, b"verification message")
    producer.flush()
    producer.close()

    consumer = KafkaConsumer(bootstrap_servers=[bootstrap_server])
    tp = TopicPartition(topic, 0)
    consumer.assign([tp])
    consumer.seek_to_beginning()
    assert consumer.end_offsets([tp])[tp] == 1, \
        "Expected exactly one test message to be present on test topic !"

if __name__ == '__main__':
    test_kafka_confluent_7_1_3()

Runtime environment

Windows 10
Testcontainers 3.6.0
kafka-python 2.0.2

I am running the snippet above in pipenv, so it is not Docker in Docker.

Will update if I find a solution.

Exécuter l’extrait KafkaContainer fourni sous pytest sur Windows 10 avec Testcontainers 3.6.0, puis inspecter le point d’entrée DockerClient.port indiqué dans le traceback et le paramètre TC_HOST. C’est terminé lorsque le conteneur démarre avec son port mappé et que les assertions du producteur/consommateur Kafka réussissent sous pytest comme lors de l’exécution en tant que script.
