Introduction

Kubernetes is an open-source platform designed to automate deploying, scaling, and operating application containers. In this guide, you will learn how to create your first deployment on a Kubernetes cluster. This setup can be effectively hosted on a Windows VPS UK for optimal performance.

Prerequisites

• A Kubernetes cluster up and running (can be a local cluster like Minikube or a cloud-based cluster)
• kubectl installed on your local machine
• Basic knowledge of Linux commands and YAML syntax

Step 1: Verify Kubernetes Cluster

Check if your Kubernetes cluster is running by executing:

kubectl cluster-info

You should see information about the Kubernetes master and the DNS services.

Step 2: Create a Deployment Configuration File

Create a YAML file for your deployment configuration. You can name it deployment.yaml:

nano deployment.yaml

Add the following content to define a simple Nginx deployment:

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

Step 3: Apply the Deployment

Use the following command to create the deployment on your Kubernetes cluster:

kubectl apply -f deployment.yaml

This command will create the deployment as specified in your YAML file.

Step 4: Verify the Deployment

Check the status of your deployment with:

kubectl get deployments

You should see your nginx-deployment listed with the desired number of replicas.

Step 5: Expose the Deployment

Expose your deployment to make it accessible from outside the cluster:

kubectl expose deployment nginx-deployment --type=NodePort --port=80

Step 6: Access Your Application

To access your Nginx application, you need to find out the NodePort assigned:

kubectl get services

Note the port number and access your application at http://:.

Step 7: Conclusion

You have successfully created your first deployment on a Kubernetes cluster. This foundational knowledge allows you to efficiently manage applications in a containerized environment. Hosting your Kubernetes cluster on a Windows VPS can enhance performance and reliability.
