docker：npm 錯誤！ 恩恩恩恩

Question

您好，我有以下設置 docker：

docker-compose.yml：

version: "3"

services:
  micro-hr:
    build: ./backend/micro-hr
    entrypoint: ./backend/micro-hr/.docker/entrypoint.sh
    container_name: micro-hr
    environment:
      - CHOKIDAR_USEPOLLING=true
    ports:
      - 3001:3000
    volumes:
      - .:/home/node/app

dockerfile：

FROM node:12.14.0-alpine3.11

RUN apk add --no-cache bash git

RUN touch /home/node/.bashrc | echo "PS1='\w\$ '" >> /home/node/.bashrc

RUN npm config set cache /home/node/app/.npm-cache --global

WORKDIR /home/node/app

COPY --chown=node:node . ./

COPY package*.json .env ./

USER node

和入口點.sh

#!/bin/bash

npm config set cache /home/node/app/.npm-cache --global

cd /home/node/app

npm install
npm run start:dev

但我在 docker-compose 上遇到了這個錯誤：

micro-hr              | npm WARN saveError ENOENT: no such file or directory, open '/home/node/app/package.json'
micro-hr              | npm WARN enoent ENOENT: no such file or directory, open '/home/node/app/package.json'

我曾懷疑它與節點用戶有關，但我在沒有測試的情況下進行了測試，但不是我通過 docker-compose 日志得到的。

Answer 1

你的 docker-compose.yml 說

volumes:
      - .:/home/node/app

刪除這兩行，在本地構建應用程序（沒有 Docker），並且只在部署時構建 Docker 圖像。

有關進一步的解釋，請參閱此docker-compose 無法以 npm 啟動 ERR：enoent ENOENT，沒有此類文件或目錄。 打開“/usr/src/app/package.json”
