码头建设+私人NPM（+私人码头中心） [英] docker build + private NPM (+ private docker hub)

问题描述

我有一个在Docker容器中运行的应用程序。它需要公司的私有NPM注册表（Sinopia）中的一些私有模块，并且访问这些模块需要用户认证。 Docker文件是 FROM iojs：latest 。

我尝试过：

1）在项目根目录下创建一个.npmrc文件，这实际上没有区别，npm似乎忽略它
2）使用env变量 NPM_CONFIG_REGISTRY ， NPM_CONFIG_USER 等，但用户没有登录。

本质上，我似乎有没有办法在 docker build 进程中验证用户。我希望有人可能已经遇到这个问题（似乎是一个明显的问题），并且将有一个很好的解决方法。

（顶一下，我使用Docker Hub上的自动构建（触发推送），以便我们的服务器可以使用预构建的映像访问私有Docker注册表。）

有很好的方法以下任一项：
1）在构建时注入NPM的凭据（所以我不必将凭据提交给我的Docker文件）OR
2）以另一种方式，我没有想到
？

解决方案

我发现一个有点优雅的ish解决方案为你的node.js / io.js创建一个基本的图像容器（ you / iojs ）：

1. 登录到您的私人npm注册表您要用于docker的用户


2. 复制生成的 .npmrc 文件






示例 .npmrc ：

  registr y = https：//npm.mydomain.com/ 
 username = dockerUser 
 email = [e-mail] 
 strict-ssl = false 
 always-auth = true 
 //npm.mydomain.com/:_authToken=\"someAuthToken
  







3. 创建一个 Dockerfile ，可以适当地复制 .npmrc 文件。



这是我的 Dockerfile （根据 iojs：onbuild ）：

  FROM iojs：2.2.1 
 
维护者YourSelf 
 
＃从图像中排除NPM缓存
 VOLUME /root/.npm 
 
＃创建应用程序目录
 RUN mkdir -p / usr / src / app 
 WORKDIR / usr / src / app 
 
＃复制npm配置
 COPY .npmrc /root/.npmrc 
 
＃安装应用程序
 ONBUILD COPY包.json / usr / src / app / 
 ONBUILD RUN npm install 
 ONBUILD COPY。 / usr / src / app 
 
＃运行
 CMD [npm，start] 
  







4. 使所有的node.js / io.js容器 FROM你/ iojs 和你很好去。






I have an application which runs in a Docker container. It requires some private modules from the company's private NPM registry (Sinopia), and accessing these requires user authentication. The Dockerfile is FROM iojs:latest.

I have tried:

1) creating an .npmrc file in the project root, this actually makes no difference and npm seems to ignore it 2) using env variables for NPM_CONFIG_REGISTRY, NPM_CONFIG_USER etc., but the user doesn't log in.

Essentially, I seem to have no way of authenticating the user within the docker build process. I was hoping that someone might have run into this problem already (seems like an obvious enough issue) and would have a good way of solving it.

(To top it off, I'm using Automated Builds on Docker Hub (triggered on push) so that our servers can access a private Docker registry with the prebuilt images.)

Are there good ways of either: 1) injecting credentials for NPM at build time (so I don't have to commit credentials to my Dockerfile) OR 2) doing this another way that I haven't thought of ?

解决方案

I found a somewhat elegant-ish solution in creating a base image for your node.js / io.js containers (you/iojs):

1. log in to your private npm registry with the user you want to use for docker
2. copy the .npmrc file that this generates

Example .npmrc:

registry=https://npm.mydomain.com/
username=dockerUser
email=[e-mail]
strict-ssl=false
always-auth=true
//npm.mydomain.com/:_authToken="someAuthToken"

3. create a Dockerfile that copies the .npmrc file appropriately.

Here's my Dockerfile (based on iojs:onbuild):

FROM iojs:2.2.1

MAINTAINER YourSelf

# Exclude the NPM cache from the image
VOLUME /root/.npm

# Create the app directory
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

# Copy npm config
COPY .npmrc /root/.npmrc

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

# Run
CMD [ "npm", "start" ]

4. Make all your node.js/io.js containers FROM you/iojs and you're good to go.
