如何讓我的 NodeJS 應用程序在 Docker 中啟動

Question

我有一個 NodeJS（版本 8）應用程序，我試圖在 Docker 本地運行。

在構建后使用docker-compose up ，我收到此錯誤：

app_1       | /app/backend/node_modules/.bin/node: 1: /app/backend/node_modules/.bin/node: �����H: not found
app_1       | /app/backend/node_modules/.bin/node: 2: /app/backend/node_modules/.bin/node: ���H__PAGEZERO__TEXT: not found

app_1       | npm ERR! app-backend@ start:production: `cross-env NODE_ENV=production nodemon ./server.js`
app_1       | npm ERR! Exit status 2

嘗試使用 docker run --rm -it my_app sh直接運行容器並嘗試cd backend && npm run start:production我得到同樣的錯誤。 調試日志說：

任何幫助將不勝感激。

Answer 1

把你的 NODE_ENV 放在 docker 像這樣組成：

  server:
    image: your_image
    environment:
      - NODE_ENV=production

然后你可以將你的 CMD 簡化為 CMD ["nodemon", "./server.js"]

Answer 2

在這里回答我自己的問題，以防有人看到類似的錯誤：在我的 package.json 中，我依賴於節點：

"dependencies": {
    ...
    "node": "^8.10.0",
    ...
  }

刪除此行后，docker 容器正確啟動。
