yarn 不会在 docker 容器中创建 node_modules 文件夹

Question

我正在尝试使用 dockerfile 和 docker_compose 构建一个应用程序。 一切似乎都没问题，直到涉及到yarn命令，该命令不创建 node_module 也不安装依赖项。

docker-compose 文件：

version: '2'

services:
  mdisassistant:
    env_file: .env
    build:
      context: .
      args:
        - APP_NAME=${APP_NAME}
        - APP_USER=app
    ports:
      - ${APP_PORT}:${APP_PORT}

Dockerfile：

FROM node:10.15.2-alpine

ARG APP_NAME
ARG APP_USER

RUN adduser -D -s /bin/false -h /home/$APP_USER $APP_USER $APP_USER

ENV HOME=/home/$APP_USER
WORKDIR $HOME/$APP_NAME
COPY . .
RUN chown $APP_USER:$APP_USER -R $HOME
USER $APP_USER

RUN whoami

RUN yarn install

RUN ls -la 
RUN pwd

RUN yarn build

CMD ["node", "./dist/index.js"]

输出：

如何解决这个问题？

Answer 1

您可以尝试不创建用户吗

FROM node:10.15.2-alpine

WORKDIR /app
COPY package.json .

RUN whoami

RUN yarn install
RUN ls -la 
RUN pwd


COPY . .
RUN yarn build

CMD ["node", "./dist/index.js"]

Answer 2

问题出在我用来构建 docker 容器的 docker 和 OS 版本中。

我使用 docker 版本 18.x 运行 docker docker-compose ，操作系统是 Deepin 15.11 我切换到 EleebtaryOS 版本 5.1.2 Hera 并安装了 docker 版本 19.03.6，现在一切正常。

我不知道为什么在 Deepin OS 中会发生这种情况。
