[Python] Unable to Connect to Azurite Container from Custom Engine Container in Integration...

I'm currently working on integration tests for my project, which consists of two main components: an application and an engine. Both components are deployed into Azure Container Apps. The engine scales using Azure Storage Queue. The workflow is as follows:

The application sends a request to the Azure queue. The engine consumes the request and processes it. I'm facing difficulties in establishing a connection to the Azurite container from my custom engine container. Below is the test case I'm using:

class TestEngine(BaseTestCase):

def test_integration_engine(self):
with Network() as network:
logger.info(f"Network {network.name}")
with AzuriteContainer() \
.with_network(network) \
.with_network_aliases("azurite_server") \
.with_exposed_ports(10000, 10000) \
.with_exposed_ports(10001, 10001) as azurite_container:
connection_string = azurite_container.get_connection_string()

with DockerContainer("57361aab4105730a7ff9d538e9bee44dfe9c24d57cc6e396edff7dbea2de5031") \
.with_env("blob_connection_string", connection_string) \
.with_network(network) \
.with_network_aliases("engine_app") \
.with_exposed_ports(80, 80) as container:
logger.info("Waiting for logs from engine!")
try:
wait_for_logs(container, "Starting handling", timeout=60)
logger.info("Engine processing started according to logs.")
except Exception as e:
logger.warning(f"Engine processing start logs not found within timeout: {e}")
logger.warning("Collecting logs and continuing anyway.")
# send_request_task(connection_string)

print(collect_logs(container, 200))



Note: The validation logic and docstrings have been omitted for brevity.

However, the engine process (running on a custom container) is terminated with the following error message:

raise error\nazure.core.exceptions.ServiceRequestError: <urllib3.connection.HTTPConnection object at 0x7fddad8b47c0>: Failed to establish a new connection: [Errno 111] Connection refused\n')]


Could someone help me understand why the connection to the Azurite container is being refused and how I can resolve this issue? Any guidance or suggestions would be greatly appreciated!
