If you're having trouble spinning this up on Windows, with an error message in the "fastapi-react-project-frontend", that looks like this:

fastapi-react-project-frontend-1  | /app/run.sh: line 2: $'\r': command not found
fastapi-react-project-frontend-1  | /app/run.sh: line 3: syntax error near unexpected token `$'in\r''

You can open up fastapi-react-project\frontend\run.sh in Notepad++ and replace "\r\n" (carriage-return, new-line) with "\n" (new-line). Make sure you've got the "Search mode" of "Extended" selected when you do this replacement. This fixed the problem for me!
