Docker连接上的RabbitMq失败

Question

我正在学习RabbitMQ的基础知识，将其安装在容器上。检查容器时似乎没问题。

PS C:\Users\jvidin> docker port rabbitmq
25672/tcp -> 0.0.0.0:32776
4369/tcp -> 0.0.0.0:32779
5671/tcp -> 0.0.0.0:32778
5672/tcp -> 0.0.0.0:32777
PS C:\Users\jvidin> docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                                                                                                 NAMES

但是，当尝试通过Pika Python lib连接如下时，它会失败并显示以下消息

pika.exceptions.ConnectionClosed: Connection to 127.0.0.1:5672 failed: timeout

码

import pika
connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))
channel = connection.channel()

channel.queue_declare(queue='hello')
channel.basic_publish(exchange='', routing_key='hello', body='Hello World!')
print(" [x] Sent 'Hello World!'")
connection.close()

解决方案下面正确的连接信息

connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost', port=32777))

Answer 1

您需要配置您的python客户端以使用localhost:32777。

只需检查docker port rabbitmq的输出。它显示容器端口5672映射到docker主机上的端口32777。
