使用npm init react-app启动后，Docker容器立即退出 [英] Docker container exiting immediately after starting when using npm init react-app

问题描述

我正在尝试使用react项目启动Docker容器，该项目是使用npm init react-app创建的。

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

这是我的Docker文件

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。成功创建一个映像（带有很多npm警告），然后当我运行 Docker run< image> 时，在我的终端机中输出

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

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

很快就会出现启动开发服务器... ，它在我的终端中停止运行了。如果我检查 Docker ps 我看不到任何容器在运行，如果我运行 Docker ps -a 我可以看到一个容器已启动，然后立即退出。

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日志显示上面的终端输出，任何人都遇到这种情况？仅在我的npm init react-app项目中，我的其他nodejs + express项目在完全相同的docker文件下运行良好

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

推荐答案

我尝试降级，但是没有用。对我有用的是我添加的react应用程序部门中的 docker-compose 文件：

I tried downgrading but it didn't work. What worked for me is in docker-compose file in the react app sector I added:

stdin_open: true

此处也建议使用此解决方案：在github上发布
