docker无法从本地主机访问容器

时间：2020-03-24 05:03:46

标签： node.js docker express

我无法从主机访问容器应用。我希望打http://localhost:3001/demo并得到一个简单的文本，但是容器似乎无法到达。没有防火墙处于活动状态。 这只是我为测试而构建的一个简单ExpressJS应用程序。 我正在使用Hyper-V运行Windows 10 Pro。

此外，在端口80上运行一个简单的nginx可以正常工作。 （docker run nginx -p 80:80）

这是docker version

代码和dockerfile下面（无需docker即可正常运行）

// index.js
const app = require('express')();

app.get('/demo', (req, res) => res.json('Demo!'));

const server = app.listen(process.env.PORT, () => {
    console.log(`Listening on ${server.address().address}:${server.address().port}`);
});

// Dockerfile
FROM node:latest

WORKDIR /src

ENV PORT=3001

COPY  ["express-app", "."]

EXPOSE 3001

ENTRYPOINT ["node", "index.js"]

我通过docker build -t express -f Dockerfile .构建图像

我通过docker run express -p 3001:3001

运行容器 
docker ps
4840aa7e327d  express  "node index.js -p 30…"  59 seconds ago  Up 58 seconds  3001/tcp wonderful_easley

docker logs 4840aa7e327d
Listening on :::3001

通过docker inspect 4840...进入容器进行检查

尝试禁用防火墙。

我建议转到设置并检查状态，然后将连接属性更改为专用，并仅禁用专用连接防火墙。

我有同样的错误，并且可以完全禁用防火墙。
