"Empty reply from server" 尝试 运行 webpack-dev-server 在 docker 容器内 docker-compose on windows 运行ning docker-工具箱

"Empty reply from server" when trying to run webpack-dev-server inside a docker container with docker-compose on windows running docker-toolbox

我在 docker-machine 中使用 docker-compose 访问 React 容器 运行 时遇到问题。我可以在容器内卷曲网页,但我无法在 docker-machine 内访问它(或在主机的浏览器上)。可以从 docker-machine 和主机的浏览器访问后端 Golang 容器(如代码片段所示,returns 未找到 404)。

在 docker-compose 日志中,一切似乎都 运行ning 顺利,webpack-dev-server 运行s 符合预期,我只是无法从外部访问它容器。

我正在为 windows 使用 docker 工具箱。

最好用一些片段来补充描述问题。

Docker-编写文件:

version: '2'
services:
    postgres:
        image: postgres
        environment:
            - POSTGRES_PASSWORD=postgres
    server:
        build: ./server
        command: gin
        volumes:
            - ./server:/go/src/app
        ports:
            - "8080:3000"
        environment:
            - POSTGRES_PASSWORD=postgres
    client:
        build: ./client
        command: npm start
        volumes:
            - ./client:/usr/src/app
            # mount node_modules as a workaround for it disappearing
            # after adding /client as a mounted folder
            - /usr/src/app/node_modules
        ports:
            - "9000:3000"

Docker节点容器文件:

FROM node:6.5.0-slim

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

COPY package.json /usr/src/app/
ENV NODE_ENV development
RUN npm install

docker-machine(默认)中以下命令的输出:

docker@default:~$ sudo iptables -t nat -L -n

主要问题来了:

docker@default:~$ curl 0.0.0.0:9000

curl: (52) Empty reply from server

docker@default:~$ curl 0.0.0.0:8080

404 page not found

docker@default:~$ docker ps

在节点容器内输出以下命令:

如有任何帮助,我们将不胜感激。

Webpack 开发服务器默认只监听本地主机。

如果您想在 Docker 容器之外公开它的端口,您需要明确指定要侦听的主机:

webpack-dev-server --host 0.0.0.0 --port 80
