如何修复拒绝 /app 的 Dockerfile 权限？

Question

我有一个节点 js 项目，这是相关的 Dockerfile：

FROM node:14.16.0-alpine3.13

RUN addgroup app && adduser -S -G app app
RUN mkdir /app && chown app:app /app
USER app

WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .

EXPOSE 80

CMD ["npm", "start"]

如您所见，我授予了应用程序的相关访问权限，但是当我在 ubuntu 18 服务器上运行 docker-compose up 时，我收到此错误：

Step 6/9 : RUN npm install

注意：api是我的应用服务名称。

此外，这个具有相同 dockerfile 的项目正在我的本地系统上运行 (windows)。

根据我的反复试验，我意识到不是这个命令：

$ docker-compose build
$ docker-compose up -d

我应该使用 docker-compose up -d --build 然后就可以正常工作了。
