Question

我正在Dockerfile中运行npm。

FROM node:9.11-alpine
COPY ./ /usr/src/app/
WORKDIR /usr/src/app/
RUN npm install && npm run build
ENTRYPOINT [ "npm", "run", "watch"]

当我做docker build .时，构建成功完成的可能性很小。在几分钟的时间内，如果我定期运行同一命令而不对我的Dockerfile或其他任何内容进行任何更改，则构建将成功。大多数时候，尽管我得到了

...

npm ERR! A complete log of this run can be found in:
npm ERR!     /root/.npm/_logs/2018-06-26T08_18_44_426Z-debug.log

由于构建失败，因此我无法检查/root/.npm/_logs/2018-06-26T08_18_44_426Z-debug.log（至少据我所知）。该错误表明存在连接问题，但在线npm存储库是否存在某种限制？还是码头工人像代理人一样？

是否可以通过docker使用npm来避免我不知道的错误？

Answer 1

为什么不将docker build与入口点分开，将docker run与入口点分开？

尝试：

Dockerfile

FROM node:9.11-alpine
COPY ./ /usr/src/app/
WORKDIR /usr/src/app/
RUN npm install && npm run build

然后，创建图像：

docker build -t your_image_name .

以网络模式=主机运行命令，以避免与网络有关的某些问题：

docker run -d --net=host your_image_name npm run watch

如果它不起作用，则可以通过两种方式检查日志：

启动容器共享卷：docker run -d -v /tmp/any_dir:/root/.npm/_logs/ ...：可从主机获取。
使用sh启动容器，进入容器，手动执行命令并检查日志文件：docker run -ti your_image_name sh

因此，连接问题确实是本地连接问题。我从其他位置使用了不同的wifi，我已经确认这是我所在公寓的wifi设置。由于这是我第一次同时使用npm和docker，所以我不能排除其他问题...

关于日志记录，我发现了两个很棒的docker选项，即使在容器无法构建时也可以找到日志；

docker logs <containerid>

和

docker cp <containerid>:/path/to/log.file ./local/path/of/log.file

适用于未运行的容器。这使我可以更有效地调试问题，而无需更改Dockerfile。
