SSL certificates with traefik in kubernetes.

Hello, everyday a new style execise with digitalocean. I have to say I am already learning the whole kubernetes thing. I would like to attempt this kind of deployment: On a 3 nodes cluster, already payed and on wich I am doing experiments, I would like to run Traefik as load balancer and ssl certificate manager, and behind Traefik I would like to run something, let’s say a Tomcat just for the sake of the example. So far I’m documenting myself with this:

https://www.digitalocean.com/community/tutorials/how-to-use-traefik-v2-as-a-reverse-proxy-for-docker-containers-on-ubuntu-20-04

https://www.digitalocean.com/community/questions/how-do-i-set-up-tomcat-with-kubernetes-in-digitalocean

https://doc.traefik.io/traefik/https/acme/

https://doc.traefik.io/traefik/providers/kubernetes-ingress/

https://doc.traefik.io/traefik/getting-started/install-traefik/

I am trying to wrap the things together and use Traefik instead of certificate manager. I could give you all the commands issued so far but my question is a bit more wide. Is it possible to do in digital ocean kubernetes such infrastructure? Kubernetes -> Traefik as proxy and ssl cert manager -> redirecting to Tomcat. Do you suggest some documentation that can help me learn how to deploy that?
