Create 3 Kubernetes Clusters with Minikube

Overview

Minikube allows you to run Kubernetes clusters locally for development, testing, and learning purposes. By creating multiple Minikube profiles, you can run several independent Kubernetes clusters on a single machine.

In this example, three separate Kubernetes clusters are deployed:

Cluster 1 (cluster1)
Cluster 2 (cluster2)
Cluster 3 (cluster3)

Each cluster has its own Kubernetes control plane, worker nodes, networking, and resources.

Architecture

Cluster 1

The first Minikube cluster contains:

Control Plane Components

kube-apiserver
etcd
kube-scheduler
kube-controller-manager

Worker Components

kubelet
kube-proxy
Pods and Containers

Cluster 2

The second cluster operates independently from Cluster 1.

Benefits

Separate workloads
Independent networking
Dedicated Kubernetes resources
Different application versions can be tested safely

Cluster 3

The third cluster can be used for additional environments such as staging or CI/CD testing.

Typical Usage

Development Environment
Testing Environment
Staging Environment

How It Works

Step 1: Create Cluster 1

minikube start -p cluster1

Minikube creates a Kubernetes cluster named cluster1.

Step 2: Create Cluster 2

minikube start -p cluster2

A completely separate Kubernetes cluster is created.

Step 3: Create Cluster 3

minikube start -p cluster3

The third cluster is deployed locally.

Step 4: Verify Running Clusters

List all available Minikube profiles:

Example output:

cluster1
cluster2
cluster3
