Setup Minikube
We will use minikube in to run kubernetes cluster in your local machine. You can download and install minikube from their official website: https://minikube.sigs.k8s.io/docs/.
Start and Configure a Kubernetes Cluster
Start Minkube
minikube start --kubernetes-version=v1.31.0 --cpus=2 --memory=4096This starts a cluster with 2 CPUs and 4GB of memory, running Kubernetes version 1.31.0.
You can check the cluster status:
kubectl cluster-infoWhich should return below information:
Kubernetes control plane is running at https://127.0.0.1:57821
CoreDNS is running at https://127.0.0.1:57821/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.View Cluster Configuration
Check Node information.
kubectl get nodes
kubectl describe node minikubeList system components of kubernetes such as API Server, Scheduler, Controller Manager, CoreDNS, etc.
kubectl get pods -n kube-systemAbove command should return you list like below.

Although Minikube is single-node by default, simulate multi-node behavior using Minikube profiles. Here's how to add a new Node in minikube.
minikube node addGet list of nodes again using kubectl get nodes and it should return newly added nodes.
