Question

我正在使用mongo-express。

安装在AWS EC2上，它已启动。

$ node app
Mongo Express server listening on port 8081 at localhost
Database connected
Connecting to db...
Database db connected

但是，无法从浏览器连接到端口8081。

我可以在ec2上使用wget命令下载mongo-express的index.html。

$ wget http://admin:pass@localhost:8081
--2016-02-22 02:22:25--  http://admin:*password*@localhost:8081/

顺便说一句，ec2安全组中的端口8081对我的IP开放。

config.js的以下设置是原因

site: {    // baseUrl: the URL that mongo express will be located at - Remember to add the forward slash at the stard and end!
baseUrl: '/',
cookieKeyName: 'mongo-express',
cookieSecret:     process.env.ME_CONFIG_SITE_COOKIESECRET   || 'cookiesecret',
host:             process.env.VCAP_APP_HOST                 || 'localhost',
port:             process.env.VCAP_APP_PORT                 || 8081,
requestSizeLimit: process.env.ME_CONFIG_REQUEST_SIZE        || '50mb',
sessionSecret:    process.env.ME_CONFIG_SITE_SESSIONSECRET  || 'sessionsecret',
sslCert:          process.env.ME_CONFIG_SITE_SSL_CRT_PATH   || '',
sslEnabled:       process.env.ME_CONFIG_SITE_SSL_ENABLED    || false,
sslKey:           process.env.ME_CONFIG_SITE_SSL_KEY_PATH   || '',
},

主机的值更改为“0.0.0.0”，现在可以从浏览器连接到mongo-express。

Answer 2

就我而言，我遇到了这个问题，因为我想在另一个端口 (4301) 上公开我的容器。

但快递仍在监听 8081。

要修复它，必须确实指定 VCAP_APP_HOST 和 VCAP_APP_PORT。

你可以直接在运行 cmd 中指定它，如：

docker run --network YOUR_NETWORK --name YOUR_MONGO_EXPRESS_CONTAINER_NAME -e ME_CONFIG_MONGODB_SERVER=YOUR_MONGO_SERVER_IP -e VCAP_APP_HOST=0.0.0.0 -e VCAP_APP_PORT=4301 -p 4301:4301 mongo-express

我无法从外部连接到mongo-express
