56/100 Deploy Nginx Web Server on Kubernetes Cluster

Some of the Nautilus team developers are developing a static website and they want to deploy it on Kubernetes cluster. They want it to be highly available and scalable. Therefore, based on the requirements, the DevOps team has decided to create a deployment for it with multiple replicas. Below you can find more details about it:

1. Create a deployment using nginx image with latest tag only and remember to mention the tag i.e nginx:latest. Name it as nginx-deployment. The container should be named as nginx-container, also make sure replica counts are 3.
2. Create a NodePort type service named nginx-service. The nodePort should be 30011.

First, create the yaml file which will be called nginx-deployment

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
        - name: nginx-container
          image: nginx:latest
          ports:
            - containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
  name: nginx-service
spec:
  type: NodePort
  selector:
    app: nginx
  ports:
    - port: 80
      targetPort: 80
      nodePort: 30011

Apply the configuration created above:

thor@jumphost ~$ kubectl apply -f nginx-deployment.yaml
deployment.apps/nginx-deployment created
service/nginx-service created

# Check the deployment has been successful and pods are available:
thor@jumphost ~$ kubectl get deployments
NAME               READY   UP-TO-DATE   AVAILABLE   AGE
nginx-deployment   3/3     3            3           31s
thor@jumphost ~$ kubectl get pods -l app=nginx
NAME                                READY   STATUS    RESTARTS   AGE
nginx-deployment-5b58668cfc-2zfjh   1/1     Running   0          86s
nginx-deployment-5b58668cfc-cwr5z   1/1     Running   0          87s
nginx-deployment-5b58668cfc-xdhld   1/1     Running   0          86s
