kubernetes - Internal nginx besides a k3s setup on one vps

Question

currently I run a nginx on a vps and I want to install k3s. The vps has two public reachable IP addresses and I want that the nginx on the vps itself only react to one specific of these two addresses.

Where can I realize that I can run the internal nginx besides the k3s?

Answer 1

You can do that with NodePort. You can create Nginx Service in K3S of the NodePort type.

Node port will expose your service to host on specific port.
