我使用了 docker-compose build，然后是 docker-compose up -d，但是容器在創建構建后以某種方式設法退出。我想運行一個生產服務器，這就是我使用 npm run build 的原因。嘗試 serve -s build 但最終在加載網頁時出現 404 錯誤。
uj5u.com熱心網友回復：
您的命令似乎是您的編譯命令。
容器的 CMD 命令需要像這樣永遠運行
CMD node app.js
或者 CMD npm start
另外..一些與您的問題無關的東西，如果您使用 npm install 我認為您的鎖定檔案將被忽略并重新生成。要準確安裝鎖定檔案中的內容，請使用
RUN npm ci
抱歉 - 告訴你為什么它在我的手機上不起作用比如何讓它作業更容易
FROM node:14
WORKDIR /code
COPY ./code/package.json ./code/package-lock.json /code/
RUN npm ci # install what is in lock file no package file
COPY ./code /code
RUN npm run build
RUN npm install -g serve
CMD serve -s build 3000
然后如果你想在本地嘗試服務，你可以npm install serve在你的專案中添加并保存包和包鎖定檔案，然后你就不必serve在你的容器中全域安裝，所以它變成：
FROM node:14
WORKDIR /code
COPY ./code/package.json ./code/package-lock.json /code/
RUN npm ci # install what is in lock file no package file
COPY ./code /code
RUN npm run build
# the port for the following should match the one you are exposing with docker compose:
CMD ./node_modules/.bin/serve -s build 3000
將依賴項添加serve到專案后
