Question

给出docker-compose的以下文件

version: '2'
services:
  sut:
    build: .
    command: /bin/bash  #nosetests
    depends_on:
     - mongo
  mongo:
    image: mongo

我尝试动态连接到mongo服务器。我对这个雄心勃勃的计划并没有走得太远。我假设Mongo服务器使用docker容器（名为sut）运行的服务器，例如我可以通过

直接从Python处理

MongoClient(host="localhost", port=27017)

不幸的是，我遇到了解决上述docker-compose的问题，例如：

非常感谢任何评论...

Answer 1

端口27017未发布到您的主机，因此您无法从localhost连接到它。

您可以将mongo阻止更改为

mongo: image: mongo ports: - 27017:27017

或通过docker容器名称从docker容器连接：

MongoClient(host="mongo", port=27017)

Answer 2

一段时间前，我遇到了同样的问题，还有更多，所以我写了一篇简短的文章/指南：MongoDB in Docker-compose - installation in few steps (2019)

很抱歉在我自己的博客上发布无耻的广告，但我希望它可以节省某人的时间...

使用Docker测试Mongo
