无法连接到 Mongodb。由 Docker 安装的

let dbRoute = "mongodb://mongo:27017/kgp_news"

const option = {
    socketTimeoutMS: 30000,
    keepAlive: true,
    reconnectTries: 30000,
    useNewUrlParser: true 
};

mongoose.connect(dbRoute, option)

我通过docker安装mongo。它运行端口 27017。

当我通过脚本“node index.js”运行项目时。这是工作。

但是当我通过编写 Dockerfile 构建应用程序时。无法连接到 Mongo。 MongoNetworkError: connection timed out
