Question

我有一个在本地运行的mongoDB docker，称为“ some-mongo”。在同一台计算机上，我还运行了后端服务器（由nodeJS制成）。问题是使用“ mongoose”模块将我的nodeJS服务器连接到本地mongo docker。

我通过运行以下命令启动了mongoDB docker：

docker run --name some-mongo -d mongo

我的nodeJS服务器尝试按以下方式连接到mongo docker：

const mongoose = require('mongoose');
const app = express();
//Connect to db
mongoose.connect('mongodb://local-host:27017/some-mongo')
  .then(db => console.log('DB Mongo: connected'))
  .catch(err => console.log(err));

问题是出现以下错误：

Server on port 3000
{ MongoNetworkError: failed to connect to server [local-host:27017] on first connect [MongoNetworkError: getaddrinfo ENOTFOUND local-host local-host:27017]

如果在单个Docker容器中运行它，则必须像这样公开端口buckets：

但是将docker run --name some-mongo -d mongo -p 27017:27107与mongoDB和app一起用作容器化应用程序将是一种更为安全的方法。这样，您就不必在docker基础架构外部暴露mongo端口。

无法使用nodeJS连接到我的mongoDB docker
