用DockertestingMongo
给了docker-compose的以下文件
version: '2' services: sut: build: . command: /bin/bash #nosetests depends_on: - mongo mongo: image: mongo 我尝试连接到一个mongo服务器。 这个雄心勃勃的计划，我没有太多的了解。 我假设Mongo服务器在docker容器（名为sut）上运行的服务器，例如我可以直接从Python进行寻址
MongoClient(host="localhost", port=27017)
不幸的是，我面临着解决上述docker问题的问题 – 例如：

任何意见都非常感谢…
端口27017不会发布到您的主机，所以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)
