Question: Cannot start KafkaContainer() (on windows(?))

I am trying to create a KafkaContainer for my integration test, but I have issues starting it.

Using testcontainers==4.12.0, the following snippet has no issues:

from testcontainers.kafka import KafkaContainer
kafka_container = KafkaContainer()
kafka_container.start()
kafka_bootstrap_servers = cls.kafka_container.get_bootstrap_server()

However, upgrading to testcontainers==4.14.2, the same snippet gives the following issue:

Traceback (most recent call last):
  File "...\test.py", line 42, in setUpClass
    cls.kafka_container.start()

    self.tc_start()

ConnectionError: Port mapping for container 06001694f7ed34dac7f89c4f3a3488d23a884338ec2cc8b367120c2452d39382 and port 9093 is not available

I did a simple investigation and found out that the waiting logic has changed between these two tags. When I use tag 13.0 and 13.1, there is a "legacy deprecation warning" but KafkaContainer can still be started.

...\test.py:40: DeprecationWarning: The wait_for_logs function with string or callable predicates is deprecated and will be removed in a future version. Use structured wait strategies instead: container.waiting_for(LogMessageWaitStrategy('ready')) or container.waiting_for(LogMessageWaitStrategy(re.compile(r'pattern')))
  wait_for_logs(cls.kafka_container, "started")

Specifically, the ConnectionError I mentioned above occurred when I upgraded 13.1 to 13.2. The changes I suspect could cause this would be this line

Not sure if this is caused by wrong usage of the library or my personal setup. It is worth noting that I have to disable Ryuk when running the code snippet (using TESTCONTAINERS_RYUK_DISABLED=true) and I am running the code snippet from Windows cmd.

Let me know if there are more information I could provide to investigate this further

Start with testcontainers/kafka/init.py and testcontainers/core/docker_client.py, focusing on the waiting and port-mapping changes between v4.13.1 and v4.13.2. Reproduce the supplied KafkaContainer snippet on Windows with Ryuk disabled, then verify that the container starts and get_bootstrap_server() returns a usable endpoint.
