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

Bắt đầu với testcontainers/kafka/init.py và testcontainers/core/docker_client.py, tập trung vào các thay đổi về việc chờ và ánh xạ cổng giữa v4.13.1 và v4.13.2. Tái hiện đoạn mã KafkaContainer được cung cấp trên Windows với Ryuk bị vô hiệu hóa, sau đó xác minh rằng container khởi động và get_bootstrap_server() trả về một endpoint có thể sử dụng.
