将NodeJS MongoClient连接到使用Docker的localhost mongodb

macOS Sierra

MongoDB Enterprise> db.version（）=> 3.4.7

Node.js 8.9.0

Docker Image Inspect => gist

我有这个代码在Node中运行，然后在一个Docker容器中运行，现在不在Docker容器中运行，下面的容器错误输出。 错误引用了昨天和今天之间触发的拓扑问题。 我不知道那是什么意思。 我能想到的唯一的事情是将nvm从8.2.1切换到8.9.0。 转回没有帮助。 添加重新连接参数也没有帮助。 任何想法将不胜感激。

更新：如果我将uri更改为azure cosmosdb实例，则会运行相同的代码。 所以它只是连接到不想连接的本地mongodb的连接string。 再次，跑了昨天，只是更新。 不知道这里发生了什么….

Hi mongodb://localhost:27017/visafrenchtech MongoDB connecting to mongodb://localhost:27017/visafrenchtech MongoError: failed to connect to server [localhost:27017] on first connect [MongoError: connect ECONNREFUSED 127.0.0.1:27017] at Pool.<anonymous> (/app/node_modules/mongodb-core/lib/topologies/server.js:336:35) at emitOne (events.js:116:13) at Pool.emit (events.js:211:7) at Connection.<anonymous> (/app/node_modules/mongodb-core/lib/connection/pool.js:280:12) at Object.onceWrapper (events.js:317:30) at emitTwo (events.js:126:13) at Connection.emit (events.js:214:7) at Socket.<anonymous> (/app/node_modules/mongodb-core/lib/connection/connection.js:187:49) at Object.onceWrapper (events.js:315:30) at emitOne (events.js:116:13) 

Node.js输出是
