Question

我能够从cmd启动代码并使用mongodb运行但是docker构建代码并且docker运行它会生成此错误：

/usr/src/app/node_modules/mongoose/node_modules/mongodb/lib/server.js:265
        process.nextTick(function() { throw err; })
                                      ^
MongoError: failed to connect to server [127.0.0.1:27017] on first connect
    at null.<anonymous> (/usr/src/app/node_modules/mongoose/node_modules/mongodb/node_modules/mongodb-core/lib/topologies/server.js:325:35)

我的app.js正在侦听端口8080，我在dockerfile上暴露了端口8080和27017。我可以知道我还应该做些什么来解决这个错误。我是初学者，请原谅我。

Answer 1

您只展示8080以及它无法连接27017的原因！而不是-p 8080:8080使用-P来暴露27017！所以你构建命令就是这样：

docker run -P -d ryan/edocker

无法从Docker化节点程序连接到Localhost Mongodb
