在Docker中的webpack-dev-server
我从中提起docker文件

# Dockerfile (tag: v3) FROM node:4.7 RUN npm install webpack -g WORKDIR /webCode/ COPY package.json . RUN npm config set registry http://registry.npmjs.org/ && npm install WORKDIR /usr/src/app COPY . /usr/src/app/ RUN cp -a /webCode/node_modules /usr/src/app/ RUN webpack CMD npm run start EXPOSE 8080 我在我的package.json文件中"start": "webpack-dev-server --host 0.0.0.0" 。
在terminal它运行良好。 但是，当我使用浏览器连接到本地主机：8080它显示拒绝连接错误。
以下是我从docker run -t容器得到的内容

在terminal上，当我运行webpack-dev-server –host 0.0.0.0它工作正常。 我想知道为什么我不能通过运行docker命令查看主页。
你忘了映射你的端口？ 尝试
docker run -p 8080:8080 your_image
