在退出代码为0的Docker容器中退出的React应用 [英] React app exiting in docker container with exit code 0

问题描述

我正在尝试使用nginzx，flask和react创建一个docker-compose安装程序.我以react-create-app( https://github.com/facebook/create-react-app )，并且尚未对其进行任何更改.

I am trying to create a docker-compose setup with nginzx, flask, and react. I started my react app with react-create-app (https://github.com/facebook/create-react-app) and haven't changed anything from it yet.

我的react应用程序的Dockerfile是:

My Dockerfile for the react app is:

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:

烧瓶和nginx容器启动正常，react的输出为:

The flask and nginx containers start fine, the output for react is:

react    | > react-scripts start

推荐答案

在我的docker-compose文件中添加:stdin_open: true解决了我的问题.

Adding: stdin_open: true to my docker-compose file fixed my issue.
