Docker container exiting immediately after starting when using npm init react-app

Question

I am trying to start a Docker container with a react project, the project is created using npm init react-app.

This is my docker file

# Specify a base image
FROM node:alpine

WORKDIR /usr/app

# Install some depenendencies
COPY ./package.json ./
RUN npm install
COPY ./ ./

# Default command
CMD ["npm", "run", "start"]

Docker build . creates an image successfully (with a lot of npm warnings) and then when I run Docker run <image> this is the output in my terminal

> mytest@0.1.0 start /usr/app
> react-scripts start

? ?wds?: Project is running at http://172.17.0.2/
? ?wds?: webpack output is served from 
? ?wds?: Content not from webpack is served from /usr/app/public
? ?wds?: 404s will fallback to /
Starting the development server...

Soon as it hits Starting the development server... it stops running in my terminal. If I check Docker ps I can see no containers are running, if I run Docker ps -a I can see a container was started up and then exited immediately.

Docker logs shows the terminal output above, anybody run into this situation? Its only with my npm init react-app project, my other nodejs + express projects run fine with the exact same docker file

Answer 1

我尝试降级，但没有奏效。对我有用的是docker-compose我添加的反应应用程序部门的文件：

stdin_open: true

此处也建议使用此解决方案：github 上的问题

Answer 2

docker run -it -p 80:3000 imagename 解决我的问题。

Answer 3

运行命令-it对我有用：

docker run -it -p 3001:3000 Imageid

Answer 4

我解决了这个问题。在 package.json 中将 "react-scripts": "3.4.1" 替换为 "react-scripts": "3.4.0"

然后重建图像，它的工作原理！他们搞砸了 react-scripts": "3.4.1" 只需使用 3.4.0 版
