构建Node / Docker时无法获取uid / gid

Question

我的Dockerfile使用Alpine并在全球范围内安装react-scripts。尝试安装时，失败并显示“无法获取uid / gid”错误。我在npm install -g命令中添加了“ --unsafe-perm”选项。docker容器已成功创建，但是容器中的权限已通过消息通知已安装的文件。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中，但这无济于事。

RUN npm -g config set user root

建立错误

Error: could not get uid/gid

Answer 1

检查这是否链接到nodejs / docker-node问题813：

根本原因似乎是：线程堆栈大小

新线程的默认堆栈大小glibc是根据控制主线程堆栈（RLIMIT_STACK）的资源限制确定的。
它通常最终为2-10 MB。

有三种可能的解决方案：

• 与高山团队讨论以解决此问题。已经有一些讨论
• 如下所示在节点docker alpine映像中修复它
• npm_config_unsafe_perm=true在解决之前，请在Docker映像中将default设置为解决方法。

您已经尝试了第三种选择，但也请考虑：

或者，您应该切换到苗条（Debian）变体，直到Alpine团队解决此问题为止。

当我在对我的React应用程序进行Docker处理时，我在Docker中遇到了节点高山图像的相同问题

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"]
