【问题描述】:
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。它正在工作。
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

【问题讨论】:
-
mongo在 node.js 服务器中,你可以ping mongo吗?和 telnet 到端口27017 -
@ThanhNguyenVan 我尝试了这个结果:PING mongo.com (54.173.82.137) 56(84) 字节的数据。它似乎工作。
