I am pretty new to Docker and I want to dockerize my react app, the index.html file is under my public folder in the react project. When I run the docker image, it fails and gives me an error stating that the index.html file is missing.
The error:
[email protected] start react-scripts start
Could not find a required file. Name: index.html Searched in: /app/public npm notice npm notice New minor version of npm available! 8.11.0 -> 8.19.2 npm notice Changelog: https://github.com/npm/cli/releases/tag/v8.19.2 npm notice Run

Below is the code of my Dockerfile:
