在Docker之外,redis和rabbitmq的ip地址被设置为' localhost'在我的django应用程序在ubuntu 16.04环境中。但是,我正在尝试将我的Web服务迁移到docker中。我使用Docker的官方存储库redis和rabbitmq。
在我的Django settings.py
中,我必须说明redis和rabbitmq的ip地址,以便在我的应用程序中连接它们。我不知道如何在Docker中确定他们的IP地址。在docker-compose.yml中,配置如下:
version: '2'
services:
# RabbitMQ
rabbit:
hostname: my-rabbit
image: rabbitmq:3
ports:
- "5672:5672" # we forward this port because it's useful for
debugging
- "15672:15672" # here, we can access rabbitmq management plugin
#Redis
redis:
image: redis:latest
#Data Processing WS
web:
build: .
command: python manage.py runserver 0.0.0.0:9060 --noreload
volumes:
- .:/srv
ports:
- "9060:9060"
links: ["rabbit", "redis"]
当我尝试将他们的IP设置为' localhost'时,会发生错误
settings.CONNECTION = pika.BlockingConnection(pika.ConnectionParameters(host=settings.RABBIT_MQ_
IP_ADDRESS, heartbeat_interval=0))
web_1 | File "/usr/local/lib/python2.7/dist-
packages/pika/adapters/blocking_connection.py", line 339, in __init__

web_1 | File "/usr/local/lib/python2.7/dist-

web_1 | File "/usr/local/lib/python2.7/dist-

web_1 | raise exceptions.ConnectionClosed()
web_1 | pika.exceptions.ConnectionClosed

在docker-compose.yml
my-rabbit
作为主机名,但在links
部分,您有rabbit
。这些需要匹配。
尝试将RabbitMQ主机名更改为rabbit
。
此外,对于web
服务,您应指定此网络应用depends on rabbit
和redis
。这样可以确保在rabbit
之前启动redis
和web
。根据您的错误,当网络启动时,RabbitMQ可能还没有完全启动。
depends_on:
- rabbit
- redis
