React应用退出代码在Docker容器中退出的应用

docker

我正在尝试使用nginzx,flask和react创建一个docker-compose设置。我使用react-create-
app(https://github.com/facebook/create-react-
app)启动了我的react应用程序,但尚未对其进行任何更改。

我的react应用程序的Dockerfile是:

FROM node:10

WORKDIR /usr/src/app

# Install app dependencies
# A wildcard is used to ensure both package.json AND package-lock.json are copied
COPY package*.json ./
RUN npm install --verbose

# Bundle app source
COPY . .


EXPOSE 3000
CMD ["npm", "start"]

撰写脚本为:

version: '3.1'

services:
    nginx:
        image: nginx:1.15
        container_name: nginx
        volumes:
            - ../:/var/www
            - ./nginx-dev.conf:/etc/nginx/conf.d/default.conf
        ports:
            - 80:80
        networks:
            - my-network
        depends_on:
            - flask
            - react
    react:
        build:
            context: ../react-app/
            dockerfile: ./Dockerfile
        container_name: react
        volumes:
            - ../react-app:/usr/src/app
        networks:
            my-network:
                aliases:
                    - react-app
        expose:
            - 3000
        ports:
            - "3000:3000"
    flask:
        ...
networks:
    my-network:

flask和nginx容器启动正常,react的输出为:

添加:stdin_open: true到我的docker-compose文件的React组件中,解决了我的问题。
