无法从docker容器内的python连接redis

Dockerfile

FROM python:3.6-slim

ENV PYTHONUNBUFFERED 1
WORKDIR /usr/src/duck

COPY ./ /usr/src/duck

RUN apt-get update
RUN apt-get install -y redis-server

RUN pip install -r requirements.txt

CMD ["/bin/bash","-c","python manage.py runserver 0.0.0.0:8000"]

python代码：

import redis
red = redis.StrictRedis(host="redis", port=6379, db=0)
red.set("working", "yes")

在这里，我试图对python和redis进行dockerize。 上面是我的Dockerfile和python代码

Traceback (most recent call last):

    response = get_response(request)

    red.set("working", "yes")

    return self.execute_command('SET', *pieces)

    connection = pool.get_connection(command_name, **options)

    connection.connect()
File "/usr/local/lib/python3.6/site-packages/redis/connection.py", line 497, in connect
    raise ConnectionError(self._error_message(e))
redis.exceptions.ConnectionError: Error -2 connecting to redis:6379. Name or service not known.

这让我犯了以下错误：

在运行python代码时

    response = get_response(request)

请看一看。

容器只运行python服务器，而不是redis。 您应该在另一个容器上启动redis服务器（可能redis默认映像也可以）。让python服务器指向它

您很幸运，因为compose文档有一个python应用程序和Redis服务器的示例。

Redis可能没有在容器内运行。仅仅在docker中安装redis服务器并不足以启动它。您可能需要这样的东西：在docker中运行多个进程（python+redis）。redis可能没有在容器中运行。仅仅在docker中安装redis服务器并不足以启动它。您可能需要这样的东西：在docker中运行多个进程（python+redis）。是否可以不使用docker compose？正如@rdas所评论的，您可以让您镜像运行这两个应用程序。他建议：我在生产中使用了这个：您可以

docker运行这两个容器，而无需特别编写。您还需要
docker network创建anyname
，并确保在
--net anyname
上启动两个容器，以便它们可以看到对方。每个容器一个进程通常被认为是最佳实践。是否可以不使用docker compose？正如@rdas评论的那样，您可以让映像运行这两个应用程序。他建议：我在生产中使用了这个：您可以
