无法连接由Docker安装的Mongodb。
let dbRoute = "mongodb://mongo:27017/kgp_news"
const option = {
socketTimeoutMS: 30000,
keepAlive: true,
reconnectTries: 30000,
useNewUrlParser: true
};
mongoose.connect(dbRoute, option)
我使用docker安装了Mongo,它运行在27017端口。
当我运行脚本"node index.js"时,它可以工作。
但是,当我通过编写Dockerfile构建应用程序时,无法连接到Mongo。
