Minikube NGINX Setup: Deploying and Exposing NGINX on Kubernetes

Minikube-NGINX Setup

This guide will walk you through running an NGINX app on a Minikube cluster. Follow the instructions below to set up the necessary Kubernetes configurations and deploy your NGINX app.

Prerequisites

• Minikube installed and running
• kubectl installed
• Basic knowledge of Kubernetes and YAML configuration files

Steps

1. Start Minikube

First, start your Minikube cluster. This command will initiate a local Kubernetes cluster using Minikube.

minikube start

2. Create a Project Directory

Create a new directory for your project and navigate into it.

mkdir Project
cd ./Project/

3. Create Deployment File

Now, create a deployment.yaml file using the following command. You will edit this file to define the Kubernetes Deployment for NGINX.

New-Item deployment.yml
New-Item deployment.yaml
rm ./deployment.yml
notepad deployment.yaml

Edit the deployment.yaml file to define the NGINX deployment. Example 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

4. Apply the Deployment

Once the deployment.yaml file is ready, apply the deployment configuration to the Minikube cluster.

kubectl apply -f deployment.yaml

5. Create Service File

Next, create a service.yaml file to expose your NGINX app as a service.

New-Item service.yaml
notepad service.yaml

Edit the service.yaml file with the following content:

apiVersion: v1
kind: Service
metadata:
  name: access-app-service
spec:
  selector:
    app: nginx
  ports:
    - protocol: TCP
      port: 80
      targetPort: 80
  type: NodePort

6. Apply the Service Configuration

After editing the service.yaml file, apply the service configuration.

kubectl apply -f service.yaml

7. Verify Kubernetes Resources

Check the nodes and services to ensure that the deployment and service are running.

kubectl get nodes
kubectl get services

On AKS // Expose through browser

kubectl expose deployment access-app-deployment \
  --name=access-app-service \
  --type=LoadBalancer \
  --port=80 \
  --target-port=80

8. Access the Service

To access your NGINX app, use the following command to open the service in your default browser.

minikube service access-app-service

This will expose your NGINX app on a Minikube local IP.

Conclusion

Now you have successfully deployed an NGINX application on Minikube and exposed it through a Kubernetes service. You can modify the deployment and service configurations as needed.

For more information, check the Minikube documentation and the Kubernetes documentation.
