Question

我有一个示例React项目，每次运行时

..npp install
..npm run
...
Compiled successfully!

You can now view material-kit-pro-react in the browser.

  Local:            http://localhost:3000
  On Your Network:  http://10.0.1.4:3000

Note that the development build is not optimized.
To create a production build, use npm run build.

服务器启动并运行（它使用了react-script）；但是，我的目的是对其进行dockerize，并在dockerfile下使用

FROM node:12
USER root
RUN mkdir -p /var/tmp/thermo && chown -R root:root /var/tmp/thermo
WORKDIR /var/tmp/thermo
COPY * ./
RUN npm install
EXPOSE 3000
CMD [ "npm", "run","start"]

我可以成功制作图像，但是当我运行docker文件时，由于该程序存在，因此我看到以下日志n

[root@*****]# docker logs 5edbd29016bd

> material-kit-pro-react@1.9.0 start /var/tmp/thermo
> react-scripts start

Could not find a required file.

在我的VM上不进行dockerization运行时，我看不到此类错误。

Answer 1

在您的dockerfile中更改

COPY * ./

到

复制。 ./

然后再次构建它，然后运行，将对其进行修复。

我的React应用程序可以在VM上运行，但不能在Docker上运行
