Step-by-Step Kubernetes Deployment Using Commands Only

We will deploy the ram1uj/easy-recipes application in Kubernetes without YAML files, using only kubectl commands.

---

Steps to Deploy the Application

1. Start Kubernetes Cluster (if not running)
2. Create a Deployment
3. Expose the Deployment as a Service
4. Verify Deployment and Access the Application

---

Step 1: Start Kubernetes Cluster

If you don’t have a running cluster, start Minikube (for local testing):

minikube start

Verify the cluster:

kubectl cluster-info

---

Step 2: Deploy the Application

Run the following command to create a Deployment with 2 replicas:

kubectl create deployment easy-recipes --image=ram1uj/easy-recipes --port=80 --replicas=2

This creates a Deployment named easy-recipes running ram1uj/easy-recipes.

---

Step 3: Expose the Deployment as a Service

Now, expose the deployment so it is accessible:

kubectl expose deployment easy-recipes --type=NodePort --port=80 --target-port=8080

This creates a Service named easy-recipes that maps port 80 to the application running on port 8080.

---

Step 4: Verify Deployment and Access the App

Check if the Pods are Running

kubectl get pods

You should see 2 running pods.

---

Check the Service Details

kubectl get svc easy-recipes

• If running in cloud, note the External IP.
• If using Minikube, get the URL:

  minikube service easy-recipes --url
  

---

Access the Application

• Open in your browser:

  http://<EXTERNAL-IP>:80
  

• Or, use Minikube to open it automatically:

  minikube service easy-recipes
  

---

Cleanup (Optional)

To delete the deployment and service:

kubectl delete deployment easy-recipes
kubectl delete service easy-recipes
