Question

我有在React上运行的应用程序，该应用程序在Docker上运行。我正在寻找一种调试方法。我正在使用Visual Studio Code。这是我的Docker文件和Docker-compose文件

FROM node:boron


ARG build_env

RUN mkdir /usr/share/unicode && cd /usr/share/unicode && wget ftp://ftp.unicode.org/Public/UNIDATA/UnicodeData.txt

COPY package.json /tmp/package.json

RUN cd /tmp && npm install

COPY ./shim/RelayDefaultNetworkLayer.js /tmp/node_modules/react-relay/lib/RelayDefaultNetworkLayer.js
COPY ./shim/buildRQL.js /tmp/node_modules/react-relay/lib/buildRQL.js

RUN mkdir -p /var/www && cp -a /tmp/node_modules /var/www/

WORKDIR /var/www

COPY . ./

RUN if [ "$build_env" != "development" ]; then npm run build-webpack && npm run gulp; fi

EXPOSE 8080

CMD ["npm", "run", "--debug=5858 prod"]

我的docker-compose文件看起来像

我希望能够调试在Orion前端容器下运行的应用程序。我尝试了各种选择，但都没有成功。我已经尝试过https://codefresh.io/docker-tutorial/debug_node_in_docker/和https://blog.docker.com/2016/07/live-debugging-docker/。

对于npm run的命令语法，我可能是错的（在npm docs中找不到此命令），但是您可能需要将--debug=5858和prod参数分开，像这样：

CMD ["npm", "run", "--debug=5858", "prod"]
