Deploying DO Kubernetes cluster and linking to DO 1-click Wordpress site

Hello, I followed through the Flask app on a DO Kubernetes cluster guide here ([https://www.digitalocean.com/community/meetup_kits/getting-started-with-containers-and-kubernetes-a-digitalocean-workshop-kit]) and am looking to integrate this into an existing Worpress site I have that I made through DO’s Ubuntu 1-click install feature on a 1GB droplet.

I am wondering if it is possible to have a page on my WP site hold a public file upload box (iframe/contact form plug-in/whatever works) that sends uploaded files to my Flask app on Kubernetes. From there processing is done and the Flask app returns another file/results that I want to display on the original web page.

Alternatively I’m thinking I may need to simply send the viewer over to the web page hosting the flask app if the above isn’t possible…

Please let me know where to find guidance on this. Thanks! :)
