Minikube Networking: Services, Ingress, DNS, and LoadBalancer Emulation#

Minikube networking behaves differently from cloud Kubernetes in ways that cause confusion. LoadBalancer services do not get external IPs by default, the minikube IP may or may not be directly reachable from your host depending on the driver, and ingress requires specific addon setup. Understanding these differences prevents hours of debugging connection timeouts to services that are actually running fine.

How Minikube Networking Works#

Minikube creates a single node (a VM or container depending on the driver) with its own IP address. Pods inside the cluster get IPs from an internal CIDR. Services get ClusterIPs from another internal range. The bridge between your host machine and the cluster depends entirely on which driver you use.

Minikube Add-ons for Production-Like Environments#

A bare minikube cluster runs workloads but lacks the infrastructure that production clusters rely on – metrics collection, ingress routing, TLS, monitoring, and load balancer support. Minikube’s addon system bridges this gap with one-command installs of production components.

This prints dozens of addons with their status. Most are disabled by default. The ones worth enabling depend on what you are testing, but a production-like setup typically needs five to seven of them.
