我正在將 react 應用程式推送到 heroku 容器。Build 本身當然比較小。
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
但是當我運行時heroku container:push -a app-name web會生成令人難以置信的大小

在移動設備上作業時 - 很痛。
每個人都是這樣還是我做錯了？
謝謝
編輯：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" ]
package.json/scripts 的作業部分
"start:prod": "serve -s build",
uj5u.com熱心網友回復：
使用.dockerignore檔案（與 Dockerfile 相同的目錄）從 Docker 映像中排除不必要的內容
.env
.github
node_modules
檢查您是否可以添加其他檔案夾/檔案（檔案？）
