After having Jenkins up and running with the ports exposed, you need to expose the application to the WEB. In order to do that you should create an Ingress.
But for more simplicity you can deploy jenkins using helm, see the following link
Not sure how did you install the Harbor.
First, you should create a load balancer in AWS with DNS harbor.local, then you could get it’s external IP Address.
Second, deploy harbor with the loadBalancer settings.
After deploy complete, you can add harbor.local to your DNS or updating /etc/hosts of the client machine.
Then try login to harbor with
https://harbor.local
