Docker：npm安装在代理之后 [英] Docker: npm install behind proxy

问题描述

我有这个Docker文件：

I have this Dockerfile:

FROM node:argon

ENV http_proxy http://user:[e-mail]:3128
ENV https_proxy https://user:[e-mail]:3128

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

# Install app dependencies
COPY package.json /usr/src/app/
RUN npm install

# Bundle app source
COPY . /usr/src/app

EXPOSE 8080
CMD [ "npm", "start" ]

但是，在 npm安装步骤中，我收到此错误：

But I get this error, in npm install step:

npm信息它的工作，如果以ok npm信息结束npm@2.14.12 npm
信息使用node@v4.2.6 npm WARN package.json deployer-ui@1.0.0否

我猜是由于代理。我也试图把

I guess it is due to the proxy. I have also tried to put

RUN npm config set proxy http://user:[e-mail]:3128
RUN npm config set https-proxy http://user:[e-mail]:3128

，但仍然收到相同的错误。

but still getting the same error.

此外，在我的文件 /etc/systemd/system/docker.service.d/http- proxy.conf 我有：

Moreover, in my file /etc/systemd/system/docker.service.d/http-proxy.conf I have this:

Environment="HTTP_PROXY=http://user:[e-mail]:3128"
Environment="HTTPS_PROXY=https://user:[e-mail]:3128"

提前感谢

推荐答案

首先， https_proxy 应该使用 http 网址，而不是https url。

First the https_proxy should use an http url, not an https url.

其次，您不需要嵌入代理设置在您的Dockfile中：您可以使用构建时间变量

Second, you don't need to embed your proxy settings in your Dockfile: you can use build time variables

docker build --build-arg HTTP_PROXY = http：// user：[e-mail]：3128 - build-arg HTTPS_PROXY = http：// user：[e-mail]：3128。

最后，码头服务级别的代理设置允许docker守护进程从互联网上拉图像。这并不意味着由 docker build 执行的unix命令（ RUN 指令）将从中受益。因此，需要将它们作为生成环境变量。

Finally, proxy settings at the docker service level allows the docker daemon to pull images from internet. It does not mean the unix command executed (RUN directive) by docker build would benefit from them. Hence the need to pass them as build-time environment variables.
