在docker中无法连接到MongoDB

使用docker集线器的官方mongo镜像，我运行以下命令使其运行：

 docker run --name api -p 127.0.0.1:27017:27017 -p 127.0.0.1:28017:28017 -d mongo

然后从另一个terminalshell，我运行mongo

但是，我不断收到以下错误：

 MongoDB shell version: 3.2.3 connecting to: test 2016-02-18T13:52:08.110-0700 I NETWORK [thread1] Socket recv() errno:104 Connection reset by peer 127.0.0.1:27017 2016-02-18T13:52:08.110-0700 I NETWORK [thread1] SocketException: remote: (NONE):0 error: 9001 socket exception [RECV_ERROR] server [127.0.0.1:27017] 2016-02-18T13:52:08.110-0700 E QUERY [thread1] Error: network error while attempting to run command 'isMaster' on host '127.0.0.1:27017' : connect@src/mongo/shell/mongo.js:224:14 @(connect):1:6 exception: connect failed

我检查了容器的日志，一切似乎都正确：

docker或Mongo有什么问题？我到处寻找答案，到目前为止没有任何工作。 docker工人还是蒙戈人？

编辑：我做了一些调查，发现我不能从容器内访问互联网。我通过运行docker exec -ti api /bin/bash连接到它，然后尝试ping Google或其他东西，并且该命令只是挂起。

我似乎只能通过在--net=host docker run命令中使用--net=host来从容器到外部世界获得互联网连接。

这里的问题是 – 如果一个容器在127.0.0.1上侦听，那么主机不能将端口映射到它。

你需要听取0.0.0.0或类似的，然后-p可以到达容器的界面。

您必须告诉容器使用它自己的IP地址而不是本地主机。

例如，假设您使用expressjs生成脚手架代码， expressjs必须使用routes/index.js编写expressjs代码

 var mongodb = require('mongodb'); router.get('/thelist', function(req, res){ // Get a Mongo client to work with the Mongo server var MongoClient = mongodb.MongoClient; // Define where the MongoDB server is var url = 'mongodb://172.17.0.5:27017/dbname'; // Connect to the server MongoClient.connect(url, function (err, db) { .........

其中172.17.0.5是$CONTAINER_IP

你可以通过$ docker inspect $CONTAINER_NAME | grep IPAddress容器ip来$ docker inspect $CONTAINER_NAME | grep IPAddress $ docker inspect $CONTAINER_NAME | grep IPAddress

如果没有互联网的容器

用sudo sudo vim /etc/NetworkManager/NetworkManager.conf打开sudo vim /etc/NetworkManager/NetworkManager.conf并注释掉dns=dnsmasq这行，所以你现在有了：

 [main] plugins=ifupdown,keyfile,ofono #dns=dnsmasq [ifupdown] managed=false

编辑：服务名称，而不是IP

您现在可以使用服务名称而不是容器的IP地址，例如：

  // Define where the MongoDB server is var url = 'mongodb://api:27017/dbname';
