Creating A Load Balancer using kubernetes

Install minikube, kubectl on your system.

Minikube is used to create a local K8s cluster. After installing minikube, run the following commands to start a minikube cluster on docker.

• Create a Kubernetes cluster: You need to have a Kubernetes cluster running on Fedora. You can use a tool like kubeadm to create a cluster.
• Create a deployment: You need to create a deployment that defines the pods that will run your application. You can use a YAML file to define the deployment.
• Create a service: You need to create a service that exposes your deployment to the network. You can use a YAML file to define the service. In the YAML file, you can specify the type field as LoadBalancer to create a load balancer service.
• Deploy the service: You can deploy the service using the kubectl create command.

Step 1: minikube start --driver=kvm2

It will perform the following tasks:

• Starting control plane node minikube in cluster minikube
• Pulling base image ...

  gcr.io/k8s-minikube/kicbase..

• Preparing Kubernetes v1.28.3 on kvm.
• kubectl is now configured to use "minikube" cluster and "default" namespace by default

Step 2: Deployment of minikube(kubernetes cluster)

kubectl apply -f deployment.yaml

You should get an output similar to this:

    service/flask-test-service created
    deployment.apps/flask-test-app created

Step 3:

kubectl get po -A

kubectl get po

kubectl get svc

On the browser,

You can access your flask application in your local host browser.

minikube service flask-test-service
