Porting github.com/aws-samples/aws-saas-factory-eks-reference-architecture to DigitalOcean

[radrad]

I would like to port/replicate: Building a Multi-Tenant SaaS Solution Using Amazon EKS
https://github.com/aws-samples/aws-saas-factory-eks-reference-architecture
and use DigitalOcean managed kubernetes and an asp.net core based application level multitenant app: abp.io
This article and the youtube video at about 43:24 time mark show the process of a tenant oboarding which creates an isolated tenant creation in AWS kubernetes in its own namespace.

I would like to see how I can either new infrastructure and application deployment for a new tenat automatically and to adjust routes and TLS certificate to be associated with desired domain/subdomain name.
I have a question #195 where I mentioned using this new github.com/endless001/sail-proxy project to automate routing creationg for YARP reverse proxy can be integrated with Kubernetes as a reverse proxy managing HTTP/HTTPS traffic ingress to a Kubernetes cluster
https://github.com/microsoft/reverse-proxy/blob/main/docs/docfx/articles/kubernetes-ingress.md
Note that I am a c#.net develper so I would build this SaaS onboarding app in C# as mvc app with API.
So what is it that can accept my request for a new tenant from a web page and inform the user that he can login to the provisioned site with: https://www.newtenant1.com

Below are some of the pictures from AWS talk and article
