docker：在创建新用户后，无法运行npm安装 [英] docker: having trouble running npm install after creating a new user

问题描述

所以我有另一个后续问题，关于在CoreOS上的Docker下安装一个基于node.js的框架，每个这篇文章。

So I have another follow-up question regarding installing a node.js-based framework under Docker on CoreOS, per this post.

所以，因为 npm 关于从 package.json 通过root进行安装，我不得不创建一个非根sudo用户来安装软件包。这是我的 Dockerfile 目前看起来像我们的回购内部，构建了一个ubuntu映像：

So, because npm is finicky about installing from package.json via root, I've had to create a nonroot sudo user in order to install the package. This is what my Dockerfile currently looks like inside of our repo, building off of an ubuntu image:

# Install dependencies and nodejs
RUN apt-get update
RUN apt-get install -y python-software-properties python g++ make
RUN add-apt-repository ppa:chris-lea/node.js
RUN apt-get update
RUN apt-get install -y nodejs

# Install git
RUN apt-get install -y git

# Bundle app source
ADD . /src

# Create a nonroot user, and switch to it
RUN /usr/sbin/useradd --create-home --home-dir /usr/local/nonroot --shell /bin/bash nonroot
RUN /usr/sbin/adduser nonroot sudo
RUN chown -R nonroot /usr/local/
RUN chown -R nonroot /usr/lib/
RUN chown -R nonroot /usr/bin/
RUN chown -R nonroot /src

USER nonroot

# Install app source
RUN cd /src; npm install

我知道这是一个不利的方式来做事情，但我在另一个关于如何在这里完成npm安装的损失。当我尝试以上的时候，我们在尝试安装时收到所有软件包的错误：

I know that this is an inelegant way to do things, but I'm otherwise at a loss as to how to complete an npm install here. When I try the above, I get errors on all of the packages as they try to install:

 Error: Attempt to unlock javascript-brunch@1.7.1, which hasn't been locked
     at unlock (/usr/lib/node_modules/npm/lib/cache.js:1304:11)

 ...

有关如何修改Dockerfile的任何想法？我只能假设这是一个许可的问题，与我已经设置了可能对Docker框架特有的 nonroot 用户的方式有关;我没有问题，只是在一个香草ubuntu安装上，虽然不是从脚本。

Any thoughts as to how I should modify my Dockerfile? I can only assume that this is some permissioning issue having to do with the way that I've provisioned the nonroot user above that might be particular to the Docker framework; I have no problem doing this kind of thing on just a vanilla ubuntu install, albeit not from script.

推荐答案

所以事实证明这可能是与docker的问题。

so it turns out that this may be an issue with docker.

可以通过从 USER nonroot 切换到 RUN / bin / su nonroot 来解决这个问题之后，一切正常。

was able to get around this by switching from USER nonroot to RUN /bin/su nonroot instead, afterwards everything worked fine.
