在 docker 中运行的实时调试节点应用程序

Question

我在 Docker 上运行了内置于 React 的应用程序。我正在寻找一种调试它的方法。我正在使用 Visual Studio 代码。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

version: '2'

我希望能够调试在 orion-frontend 容器下运行的应用程序。我尝试了各种选择但没有成功。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/。

Answer 1

我可能对 npm run 的命令语法有误（在 npm 文档中没有找到此命令），但您可能需要将 --debug=5858 和 prod args 分开，如下所示：

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