I want to run a single node Kubernetes cluster on my local machine. But how? Well, this step-by-step guide will take you through all the steps required to install Minikube on Debian 12 so that you can start to learn and experiment Kubernetes on your local development system.

Installing Minikube on Debian 12

So, what are the steps to install Minikube?

Prerequisites

Before you can use Minikube, there are a number of requirements that you need to consider;

Kubernetes Concepts;

What are the core concepts in Kubernetes?

System Resources

Ensure your system has;

  • At least 2 CPUs
  • At least 2GB of free RAM
  • At least 20GB of free Disk space

Minikube Drivers

Drivers are components that Minikube uses to interact with various virtualization technologies used to run Kubernetes cluster. They can be a container or virtual machine manager, such as:Β Docker,Β QEMU,Β Hyperkit,Β Hyper-V,Β KVM,Β Parallels,Β Podman,Β VirtualBox, orΒ VMware Fusion/Workstation.

You can check how to install Docker, VirtualBox or KVM on Debian 12 by following the links below;

How to Install Docker CE on Debian 12

Install VirtualBox 7 on Debian 12

Install KVM on Debian 12

We will be using Docker in this guide to run Minikube.

Internet Access

Ensure the system has Internet connection. This is required to download various Minikube components.

Install Kubectl

Install Kuberenetes command line tool, kubectl;

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

Verify the kubectl version;

kubectl version --client --output=yaml

clientVersion:
  buildDate: "2023-06-14T09:53:42Z"
  compiler: gc
  gitCommit: 25b4e43193bcda6c7328a6d147b1fb73a33f1598
  gitTreeState: clean
  gitVersion: v1.27.3
  goVersion: go1.20.5
  major: "1"
  minor: "27"
  platform: linux/amd64
kustomizeVersion: v5.0.1

Installing Minikube on Debian 12

Installing Minikube on Debian is as easy as executing the commands below;

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube_latest_amd64.deb
sudo apt install ./minikube_latest_amd64.deb

Once the installation is done, you should be able to proceed with using Minikube.

Let’s check the version;

minikube version

Sample output;

minikube version: v1.30.1
commit: 08896fd1dc362c097c925146c4a0d0dac715ace0

Starting Minikube

We are running the next commands with a non root user;

su - kifarunix

Add your user to Docker group;

sudo usermod -aG docker $USER

Log out and login as user again

Ensure you are part of the Docker group;

id
uid=1000(kifarunix) gid=1000(kifarunix) groups=1000(kifarunix),100(users),992(docker),995(vboxsf)

Minikube Help Page

Run the command below to check Minikube help information;

minikube --help

Start Local Kubernetes cluster

You can show start Minikube local kubernetes cluster by running;

minikube start --driver=docker

So what does this command do?

  • It starts control plane node minikube in cluster.
  • Pulls the base image required to create Kubernetes cluster
  • Next, it downloads preconfigured set of Kubernetes binaries to bootstrap the cluster.
  • Setup Kubernetes on Docker
  • Configures container networking interface
  • Enable some Minikube add-ons such as for storage.

See sample output;

Check Minikube Status

You can check Minikube status using the command below;

minikube status

minikube
type: Control Plane
host: Running
kubelet: Running
apiserver: Running
kubeconfig: Configured

Administering Kubernetes on Minikube

You should now be able to administer Kubernetes on Minikube.

Minikube SSH Login

You can SSH into minikube using the command below;

minikube ssh

You land into the the minikube docker shell.

Run docker commands inside;

docker ps

Get Kubernetes Cluster Resource Information

Let’s run a few Kubernetes commands;

  • Get Kubernetes cluster information;
kubectl cluster-info

Kubernetes control plane is running at https://192.168.49.2:8443
CoreDNS is running at https://192.168.49.2:8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
  • Lists all the nodes in the current namespace.
kubectl get nodes

NAME       STATUS   ROLES           AGE     VERSION
minikube   Ready    control-plane   7h52m   v1.26.3

List all services in the current namespace;

kubectl get services

NAME         TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   10.96.0.1            443/TCP   7h53m

You can basically manage your Kubernetes cluster just as would on any prod environment.

Deploy Simple Kubernets Application

Let’s create a simple Nginx manifest file to define the desired state;

vim nginx-deployment.yaml

Paste the following content;


apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  replicas: 2
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:latest
        ports:
        - containerPort: 80

Deploy Nginx;

kubectl apply -f nginx-deployment.yaml

List deployments;

kubectl get deployments

NAME               READY   UP-TO-DATE   AVAILABLE   AGE
nginx-deployment   0/2     2            0           13s

Check the pods. You should see two of them due to replica of 2;

kubectl get pods

NAME                                READY   STATUS    RESTARTS   AGE
nginx-deployment-6b7f675859-ljsh8   1/1     Running   0          7s
nginx-deployment-6b7f675859-qvnpn   1/1     Running   0          7s

Next, you need to expose this service for external access;

vim nginx-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: nginx-service
spec:
  type: NodePort
  selector:
    app: nginx
  ports:
    - name: http
      port: 80
      targetPort: 80
      nodePort: 30000  # Choose an available port number

Ensure no other service is being exposed via port 31500/tcp defined above.

Apply the service;

kubectl apply -f nginx-service.yaml

Check the services to find out an external port to access it;

kubectl get services

NAME            TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)        AGE
kubernetes      ClusterIP   10.96.0.1               443/TCP        60m
nginx-service   NodePort    10.107.130.31           80:30000/TCP   3s

get more details;

kubectl describe service nginx-service

Name:                     nginx-service
Namespace:                default
Labels:                   
Annotations:              
Selector:                 app=nginx
Type:                     NodePort
IP Family Policy:         SingleStack
IP Families:              IPv4

IPs:                      10.107.130.31
Port:                     http  80/TCP
TargetPort:               80/TCP
NodePort:                 http  30000/TCP
Endpoints:                10.244.0.8:80,10.244.0.9:80
Session Affinity:         None
External Traffic Policy:  Cluster
Events:

Accessing the Service. You can print the url or open service on the default browser;

minikube service nginx-service

Sample browser;

Install Minikube on Debian 12

and command line output;


|-----------|---------------|-------------|---------------------------|
| NAMESPACE |     NAME      | TARGET PORT |            URL            |
|-----------|---------------|-------------|---------------------------|
| default   | nginx-service | http/80     | http://192.168.49.2:30000 |
|-----------|---------------|-------------|---------------------------|
πŸŽ‰  Opening service default/nginx-service in default browser...

Unfortunately, our service is exposed via docker bridge interface IP and hence, makes it hard to access externally.

You can do port forwarding of Nginx target port to some other unused ports as follows;

kubectl port-forward service/nginx-service --address=0.0.0.0 8080:80

Sample output;

Forwarding from 0.0.0.0:8080 -> 80
Handling connection for 8080
Handling connection for 8080

Press CTRL+C to cancel.

You should now be able to access your App outside Minikube cluster, http://<server-IP>:8080.

Install Minikube on Debian 12

You can now proceed to explore Kubernetes!

Enable Minikube Addons

Addons are components that can be used to extend the functionality of Minikube;

There is quite a number of addons;
