I am new to kubernetes and I was setting up my cluster using kubeadm where I will host some simple workloads, I initialised cluster on two VPS machines and made network for them using wireguard, I installed calico and openebs, now I have an issue, I need to install nginx ingress and make it listen 80 port on node, I know that k3s ServiceLB can do something like this, but it is exclusive for k3s, maybe we have something like this for k8s?
