用 Docker 测试 Mongo

Question

给定以下文件 docker-compose

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

我尝试即时连接到 mongo 服务器。这个雄心勃勃的计划并没有取得太大进展。我假设服务器 Mongo 服务器是运行 docker 容器（名为 sut），例如我可以直接从 Python 使用

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

不幸的是，我遇到了触发上述问题的问题docker-撰写，例如：

非常感谢任何评论...

Answer 1

端口 27017 未发布到您的主机，因此您无法从本地主机连接到它。

您可以将 mongo 块更改为

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

我前段时间遇到过同样的问题，还有一些，所以我写了一篇简短的 article/guide 关于它：MongoDB in Docker-compose - installation in few steps (2019)

抱歉在我自己的博客上做无耻的广告，但我希望它能节省别人的时间...
