I am building a dockerfile from a SPA using very basic js and html

I want to copy only some files to the docker image, but I am really struggling to do so as following: docker file commands

I have also tried several variations, i.e removing ./ from the index html, also doing it on one line using "array" style... But all these tries end up in writing the index.html content to all files, for example I will see the index html content inside the style.css,seeing it from the dev Tools on chrome. Therefore the page won't work as expected

The only workaround I have managed to get working is making a script using copy and placing everything on a "dist" folder, then copying everything on the folder to the docker image. That way it would work, but I'd prefer not to use a script and instead copy everything needed from the dockerfile straight away.

Any help is appreciated
