Deploy Full Stack Project (Angular And Spring boot) to Kubernetes, Using Helm Chart, and Nexus registry

I have a project in github (https://github.com/utrains/fastfood.git) containing :
- a frontend (Angular)
- a backend (Spring boot)
- a database in RDS.

I want to deploy these codes in kubernetes (EKS):
1- send the docker images of these codes in nexus (done through a pipeline)
2- generate the helm chart for this project, taking the images in Nexus,
3- deploy the project using the Helm Chart generator folder
4- explain and document the solution

Notes :
The backend database is a Mysql database on RDS.
