How do i fix pod discovery in a Minikube cluster with CNI issues?

[Addison_R]

I’ve been trying to set up a local Kubernetes cluster on my home server using Minikube, but I keep hitting a wall with the container networking. Every time I deploy a simple multi-pod application, the pods can’t discover each other, and I’m not sure if my issue is with the configuration of the CNI plugin or something deeper in my network setup.

I had something similar last month. Minikube booted a simple multi pod app but the pods couldn't discover each other. It felt like the network was never there. I tracked it down to how the pod network was provisioned across nodes and switching the CNI plugin fixed the cross node communication.

DNS and service discovery still gave me grief even after IPs looked healthy. I watched kubelet and kube-proxy logs for signs of policy blocks, and gradually learned that small config changes could flip traffic.

Could the real blocker be something outside Kubernetes like your home router firewall or NAT blocking the pod CIDR ranges?

Another time I wandered off into the VM driver settings and ended up chasing performance and occasional hangs, then realized I was chasing symptoms rather than the root cause.
