Deploying OpsMate Platform on AWS EKS

Business Scenario

Manager:
We have successfully created the AWS EKS cluster and configured Kubernetes resources. Now it's time to deploy the complete OpsMate platform on EKS and make it available to users.

DevOps Engineer:
That's correct. We will deploy all OpsMate components, including Deployments, Services, ConfigMaps, and Secrets, into the EKS cluster and verify that they are running properly.

Manager:
How will this improve our application availability?

DevOps Engineer:
EKS will ensure high availability, automatic scaling, self-healing, and centralized management of the OpsMate platform in a production environment.

Manager:
What is our deployment plan?

DevOps Engineer:
We will apply the Kubernetes manifests, verify Pod and Service status, expose the application, and test connectivity across all components.

DevOps Engineer to Team:
Team, we will deploy the OpsMate platform on AWS EKS, validate all Pods and Services, confirm ConfigMap and Secret integration, and ensure the application is accessible and running smoothly.

Team:
Understood. We will deploy the complete OpsMate platform on AWS EKS and verify that it is scalable, secure, and fully operational for production use.

Pre-Lab Preparation

  • Create Kubernetes namespaces

  • Organize OpsMate resources

  • Deploy the OpsMate application

  • Verify Pods and Deployments

  • Expose applications using Kubernetes Services

  • Access the application from outside the cluster

Task 1: Verify EKS Cluster Connectivity

Connect to your EC2 administration server.

Verify cluster access:

kubectl cluster-info

Verify worker nodes:

kubectl get nodes

View current context:

kubectl config current-context

Check existing namespaces:

kubectl get namespaces

Task 2: Understand Kubernetes Namespaces

What is a Namespace?

A Namespace is a logical partition inside a Kubernetes cluster.

Instead of placing every application in the default namespace, we can organize workloads separately.

Example:

EKS Cluster

│

├── development

├── testing

├── production

└── monitoring

This helps teams manage resources more efficiently.

For the OpsMate project, we will create a dedicated namespace.

Task 3: Create OpsMate Namespace

Create namespace:

kubectl create namespace opsmate

Verify namespace:

kubectl get namespaces

View namespace details:

kubectl describe namespace opsmate

Task 4: Set Default Namespace Context

Instead of specifying the namespace every time, configure kubectl to use the OpsMate namespace.

kubectl config set-context --current --namespace=opsmate

Verify:

kubectl config view --minify | grep namespace

Task 5: Create OpsMate Deployment

Create deployment file:

nano opsmate-deployment.yaml

Apply deployment:

kubectl apply -f opsmate-deployment.yaml

Verify deployment:

kubectl get deployments

Verify Pods:

kubectl get pods

Describe deployment:

kubectl describe deployment opsmate-app

Task 6: Expose OpsMate Application

Currently Pods are running only inside the cluster.

External users cannot access them.

Create a Service.

nano opsmate-service.yaml

Apply configuration:

kubectl apply -f opsmate-service.yaml

Verify Service:

kubectl get svc

Task 8: Access the Application

Copy the external DNS name:a123456.us-east-1.elb.amazonaws.com

Task 9: Scale OpsMate Application

Increase replicas:

kubectl scale deployment opsmate-app --replicas=4

Verify:

kubectl get pods

Verify deployment:

kubectl get deployment

Task 10: Validate Application Availability

View deployment status:

kubectl rollout status deployment opsmate-app

View endpoints:

kubectl get endpoints

Verify Services:

kubectl get svc

Verify Pods:

kubectl get pods -o wide

View all namespace resources:

kubectl get all

Cleanup Resources

Delete Service:

kubectl delete -f opsmate-service.yaml

Delete Deployment:

kubectl delete -f opsmate-deployment.yaml

Delete Namespace:

kubectl delete namespace opsmate

Verify cleanup:

kubectl get namespaces

Delete the cluster 

 eksctl delete cluster --name opsmate-cluster --region us-east-1

Verify the cluster  

eksctl get cluster --region us-east-1

 

Great job!

  • Created an OpsMate namespace, deployed the application using Kubernetes Deployment, and verified Pods, Deployments, and workload organization.
  • Exposed the application using a LoadBalancer Service, accessed it through AWS Load Balancer, and scaled workloads inside the cluster.

Task 1: Understanding BRD

Before you start building anything, you need to clearly understand what the client actually wants.So, let’s begin by understanding the BRD (Business Requirement Document) shared by the client.

BRD Full Form is Business Requirement Details.BRD like a plan for building a house. This plan helps the builder understand what to build.In the same way,BRD tells developers what the client wants to build

Click to download BRD : BiteBox_BRD.pdf

Activity

After going through BRD list down the Core Features and  Web Pages in the tabulated Format as shown Below.

Col 1Col 2Col 3
Row 1
Row 2
Row 3

Formula

Profit = Revenue - Cost

Task 2: Create WireFrame

Now that you understand the requirements, don’t jump into coding yet. Before development, we always visualize the layout.

Now lets  create a simple wireframe for the homepage.

A wireframe is like a layout plan of a house. Before building, you decide where rooms, doors, and windows will be placed.Similarly, a wireframe helps you plan where elements like headers, images, and buttons will appear on a webpage—before adding design or colours.

Task 3: Code Editor Installation

Good work on completing the planning phase.

Now we will start development. Before that, make sure your system is ready with the required tools.

In this step we will install the VS code editor that will help to Write code efficiently,Organize files , Run and test your application

Go to the visual studio code official website
