Hướng nghiên cứu

Trước tiên, kiểm tra testcontainers/core/container.py tại Reaper.get_instance(), _create_instance() và DockerContainer.init, sau đó theo dõi quá trình khởi tạo DockerClient đến _retrieve_server_version trong docker/api/client.py được hiển thị trong trace. Tái hiện vấn đề bằng ví dụ test_containers được cung cấp và DOCKER_HOST; hoàn thành khi đường dẫn 4.15 không còn đệ quy và regression được bao phủ.

Mô tả

Describe the bug

It seems there is a regression after upgrading from 4.14.2 to 4.15

I was able to reproduce locally (podman) and on Kubernetes (via kubedock) and DOCKER_HOST='tcp://localhost:2475'

To Reproduce

def test_containers():
    with PostgresContainer(
        "<custom_domain>/postgres:16.4"
    ) as postgres:
        engine = sqlalchemy.create_engine(postgres.get_connection_url())
        with engine.begin() as connection:
            result = connection.execute(sqlalchemy.text("select version()"))
            (version,) = result.fetchone()
            client = TestClient(app)
            response = client.get("/api/todos/1")
            assert response.status_code == 200
            assert response.json() == {"completed": False, "id": 1, "title": "Todo 1"}
            response = client.get("/api/todos")
            assert response.status_code == 200

FAILED app/test_main.py::test_containers - docker.errors.DockerException: Error while fetching server API version: maximum recursion depth exceeded

Runtime environment

WSL podman but same behavior on kubedock (Docker API for K8S)
