獲取 pika.exceptions.StreamLostError：傳輸使用 pika 運行 python 腳本 docker 圖像時指示 EOF

Question

我正在使用 Python，它使用 RabbitMQ 作為輸入和 output。 我能夠在本地運行我的腳本而沒有任何錯誤，但是當我嘗試 Dockerize 該腳本並運行它時，它給了我以下錯誤：

Traceback (most recent call last):
File "./Kusto_connection_with_rabbitmq_2.py", line 1674, in <module>
 main()
File "./Kusto_connection_with_rabbitmq_2.py", line 1668, in main
 channel.start_consuming()
File "/usr/local/lib/python3.8/site-packages/pika/adapters/blocking_connection.py", line 1865, 
  in start_consuming
self._process_data_events(time_limit=None)
File "/usr/local/lib/python3.8/site-packages/pika/adapters/blocking_connection.py", line 2026, 
  in _process_data_events    self.connection.process_data_events(time_limit=time_limit)
File "/usr/local/lib/python3.8/site-packages/pika/adapters/blocking_connection.py", line 824, 
  in process_data_events
self._flush_output(common_terminator)
File "/usr/local/lib/python3.8/site-packages/pika/adapters/blocking_connection.py", line 523, 
in _flush_output
 raise self._closed_result.value.error
 pika.exceptions.StreamLostError: Transport indicated EOF

下面是我的 Python 代碼，它連接到 RabbitMQ：

credentials = pika.PlainCredentials(username, password)
parameters = pika.ConnectionParameters(host=Api_url,virtual_host=rmqvhost,credentials=credentials,heartbeat=0)
print (username,password)
connection = pika.BlockingConnection(parameters)
channel = connection.channel()

channel.queue_declare(queue='test',durable=True)


channel.basic_qos(prefetch_size=0,prefetch_count=1) # this is for acknowdeging packet one by one 
channel.basic_consume(queue='test', on_message_callback=callback,auto_ack=False)


print(' [*] Waiting for messages. To exit press CTRL+C')
channel.start_consuming()

我的 Dockerfile：

FROM python:3.8
WORKDIR /First_try
COPY requirements.txt .
RUN pip install -r requirements.txt
COPY Kusto_connection_with_rabbitmq_2.py .
CMD ["python","./Kusto_connection_with_rabbitmq_2.py"]

我運行我的 Docker 容器

docker run <image_name>

Answer 1

也許您的連接被中斷，而 pika 正在宣布您的客戶死亡。 嘗試將參數中的心跳設置為 30 左右。

Answer 2

我想您的問題是您無法從 docker-container 訪問 rabbitmq。

這是使用 docker-compose 的 python 中的 rabbitmq 使用的簡單示例，您應該嘗試依賴此示例來實現您的解決方案。
