node.js - 无法基于 Node :8. 1 镜像为 Node 应用程序构建 Docker 容器

Question

我正在尝试使用以下 Dockerfile 基于 node:8.1 镜像为我的应用创建一个容器:

FROM node:8.1.4


RUN mkdir /home/node/.npm-global ; \
    mkdir -p /home/node/app ; \
    chown -R node:node /home/node/app ; \
    chown -R node:node /home/node/.npm-global
ENV PATH=/home/node/.npm-global/bin:$PATH
ENV NPM_CONFIG_PREFIX=/home/node/.npm-global

USER node

WORKDIR /home/node/app

# Just for dev
RUN npm install mocha knex nodemon -g --quiet

# Opting for COPY over ADD as there is no need of auto extracting any compressed file
COPY . /home/node/app

RUN npm install --quiet

CMD node

但是，当它运行npm install --quiet时，我收到以下消息:

npm WARN deprecated <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a5cbcac1c088d0d0ccc1e5948b918b92" rel="noreferrer noopener nofollow">[email protected]</a>: Use uuid module instead

npm WARN checkPermissions Missing write access to /home/node/app/node_modules/sqlite3/node_modules/node-pre-gyp/node_modules/npmlog/node_modules/are-we-there-yet/node_modules/delegates

对于 package.json 中的每个包都会重复该消息。

最后是:

以前使用node:7.1时，我无需将当前用户更改为node即可使其工作。

如何让我的应用程序部署与此镜像的最新版本一起使用？

通过将 USER 指令移至 FROM 指令正下方并从主机卷中删除现有的 node_modules 文件夹，问题得到了解决。
