运行 docker-compose up 给出了上面的输出,但是当我尝试在浏览器上连接到服务器时,我什么也没得到:

The server at 172.18.0.2 is taking too long to respond.

Firefox can’t establish a connection to the server at localhost:3000.

我输入了端口和地址:

http://172.18.0.2:3000/

http://localhost:3000/

我没有收到任何错误消息。我正在使用我用 npx create-react-app docker-app 创建的样板项目。

有什么不对。

这是我的码头文件:

version: '3'
services:
  web: 
    build:
      context: .
      dockerfile: Dockerfile.dev
    ports: 
      - "3000:3000"
    stdin_open: true
    tty: true
    volumes:
      - /app/node_modules
      - .:/app

Dockerfile.dev:

FROM node:11.10.1-alpine

WORKDIR '/app'

COPY package.json .
RUN npm install

COPY . .

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

标签: dockerreact-create-app

解决方案


我可以看看你的 Dockerfile.dev 吗?

它应该看起来像这样:

FROM node:13
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 3000
CMD [ "npm", "start" ]
