docker 容器中安装的 npm 不可靠

Question

我在Dockerfile.

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

当我这样做时，docker build .成功完成构建的机会很小。在几分钟内，如果我定期运行相同的命令而不对我的Dockerfile或其他任何内容进行任何更改，则构建将会成功。大多数时候我都明白这一点；

...
npm WARN tar ENOENT: no such file or directory, open '/usr/src/app/node_modules/.staging/bluebird-5b126a50/js/browser/bluebird.js'
npm ERR! code ENOTFOUND

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

因为构建失败，我无法检查/root/.npm/_logs/2018-06-26T08_18_44_426Z-debug.log（至少据我所知）。该错误表明它是一个连接问题，但在线 npm 存储库是否有某种限制？或者 docker 的作用就像一个代理吗？

有没有一种方法可以将 npm 与 docker 一起使用来避免这个我不知道的错误？

为什么不将docker build无入口点和docker run有入口点分开呢？

尝试：

Dockerfile

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

之后，创建图像：

docker build -t your_image_name .

使用网络模式=主机运行命令以避免一些与网络相关的问题：

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

如果不起作用，您可以通过两种方式检查您的日志：

1. 启动共享卷的容器：：docker run -d -v /tmp/any_dir:/root/.npm/_logs/ ...可从主机获取。
2. 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
