推送到 heroku 容器时 - 生成大量数据

Question

我正在将 React 应用程序推送到 heroku 容器。 build本身当然比较小

pl@hp:~/Desktop/proj/node/fastify-react/build$ du -h .
12K ./static/css
1,5M    ./static/js
144K    ./static/media
1,6M    ./static
1,7M

但是当我运行 heroku container:push -a app-name web 时会生成令人难以置信的尺寸

The project was built assuming it is hosted at /.
You can control this with the homepage field in your package.json.

The build folder is ready to be deployed.
You may serve it with a static server:

  npm install -g serve
  serve -s build

在移动设备上工作时很痛。

大家是这样还是我做错了？

谢谢

编辑：使用的 Dockerfile

FROM node:alpine

# app inside container
WORKDIR "/app"

COPY ./package.json ./

RUN npm install

COPY . .

RUN npm run build

CMD [ "npm", "run", "start:prod" ]

包的工作部分。json/scripts "start:prod": "serve -s build",

使用 .dockerignore 文件（与 Docker 文件相同的目录）从 Docker 图像中排除不必要的内容

.env
.github
node_modules

检查是否可以添加其他 folders/files（文档？）
