构建 Node/Docker 时无法获取 uid/gid

Question

我的 Dockerfile 正在使用 alpine 并全局安装 react-scripts。当它尝试安装它时，它会因“无法获得 uid/gid”错误而失败。我在 npm install -g 命令中添加了“---unsafe-perm”选项。 docker 容器已成功创建，但容器中的权限已针对已安装的文件发出消息。我看到所有用户名和组都设置为 1000。我尝试在安装步骤之前将以下命令添加到 Dockerfile，但这没有帮助。

RUN npm -g config set user root

编译错误

Error: could not get uid/gid
[ 'nobody', 0 ]

UPD 修复了in nodejs@12.4.0?

检查这是否链接到nodejs/docker-node issue 813：

根本原因似乎是：Thread stack size

glibc 上新线程的默认堆栈大小取决于管理主线程堆栈的资源限制 (RLIMIT_STACK)。
它通常最终为 2-10 MB。

有三种可能的解决方案：

• 与 Alpine 团队交谈以解决此问题。有some discussions already
• 在node docker alpine image as follows 中修复它
• 在 docker 映像中设置默认 npm_config_unsafe_perm=true 作为解决方法，直到它被修复为止。

您已经尝试过第三个选项，但也请考虑一下：

或者，您应该切换到 slim (Debian) 变体，直到 Alpine 团队在上游修复此问题。

当我对我的 react 应用程序进行 dockerizing 时，我在 Docker 中遇到了节点高山映像的相同问题

我通过以下 dockerfile 配置解决了。

FROM node:8.10.0-alpine

# Set a working directory
WORKDIR /usr/src/app

COPY ./build/package.json .
COPY ./build/yarn.lock .

# To handle 'not get uid/gid'
RUN npm config set unsafe-perm true

# Install Node.js dependencies
RUN yarn install --production --no-progress

# Copy application files
COPY ./build .

# Install pm2
RUN npm install -g pm2 --silent


# Run the container under "node" user by default
USER node

CMD ["pm2", "start", "mypm2config.yml", "--no-daemon", "--env", "preprod"]
