Deploy Apache HTTPD on Kubernetes: Namespace, Deployment & NodePort Service

  Our course you can check :-   Udemy course  

Ques:- 

There is an application that needs to be deployed on Kubernetes cluster under Apache web server. Application development team has asked the DevOps team to deploy it. We need to develop a template as per requirements mentioned below:

Create a namespace named as httpd-namespace-devops.

Create a deployment named as httpd-deployment-devops under newly created namespace. For the deployment use httpd image with latest tag only and remember to mention the tag i.e httpd:latest, and make sure replica counts are 2.

Create a service named as httpd-service-devops under same namespace to expose the deployment, nodePort should be 30004.

Ans:-

Here's a complete Kubernetes manifest template that fulfills the requirements you've described:

raj@jumphost ~$ cat pod.yaml 

apiVersion: v1

kind: Namespace

metadata:

  name: httpd-namespace-devops

---

apiVersion: apps/v1

kind: Deployment

metadata:

  name: httpd-deployment-devops

  namespace: httpd-namespace-devops

spec:

  replicas: 2

  selector:

    matchLabels:

      app: httpd-app

  template:

    metadata:

      labels:

        app: httpd-app

    spec:

      containers:

      - name: httpd-container

        image: httpd:latest

        ports:

        - containerPort: 80

---

apiVersion: v1

kind: Service

metadata:

  name: httpd-service-devops

  namespace: httpd-namespace-devops

spec:

  type: NodePort

  selector:

    app: httpd-app

  ports:

  - protocol: TCP

    port: 80

    targetPort: 80

    nodePort: 30004

raj@jumphost ~$ kubectl apply -f pod.yaml 

namespace/httpd-namespace-devops created

deployment.apps/httpd-deployment-devops created

service/httpd-service-devops created

raj@jumphost ~$ kubectl get all -n httpd-namespace-devops

NAME                                           READY   STATUS    RESTARTS   AGE

pod/httpd-deployment-devops-7b796fdd95-6xqfz   1/1     Running   0          26s

pod/httpd-deployment-devops-7b796fdd95-wstn9   1/1     Running   0          26s

NAME                           TYPE       CLUSTER-IP     EXTERNAL-IP   PORT(S)        AGE

service/httpd-service-devops   NodePort   10.96.165.52   <none>        80:30004/TCP   26s

NAME                                      READY   UP-TO-DATE   AVAILABLE   AGE

deployment.apps/httpd-deployment-devops   2/2     2            2           26s

NAME                                                 DESIRED   CURRENT   READY   AGE

replicaset.apps/httpd-deployment-devops-7b796fdd95   2         2         2       26s

raj@jumphost ~$ 

Ensure both pods are in Running state and the service is exposing port 30004.

Access the app in your browser at:

http://<NodeIP>:30004

Replace <NodeIP> with your Kubernetes node’s external IP.

Conclusion:-

Learn how to deploy an Apache HTTPD web server on a Kubernetes cluster using a hands-on YAML template. In this step-by-step tutorial, we’ll cover:

• Creating a custom namespace for DevOps teams
• Building a deployment with the httpd:latest image and 2 replicas
• Exposing the deployment using a NodePort service on port 30004

This video is perfect for DevOps engineers, Kubernetes beginners, and anyone looking to understand real-world deployment scenarios. By the end, you’ll be able to confidently deploy web applications on Kubernetes using best practices.
