This template uses Sinatra internally, and the slim Docker image for Ruby to keep the image small. A native build toolchain is installed, which still results in a smaller image than the standard Ruby image on the Docker Hub.
Ruby version: 3.3.6.

response_headers = {"content-type" => "text/html"}
body = "<html>Hello world from the Ruby template</html>"
return body, response_headers, status_code
end
endAdd a gem to the homepage/Gemfile if you need additional dependencies.
