Meru Infrastructure 🚀

Evaluate skills in systems administration, automation, and infrastructure management using core DevOps infrastructure using core DevOps technologies such as AWS, Docker, Kubernetes, Linux, Networking and Terraform.

Prerequisites

• AWS Account ans AWS CLI
• Terraform
• Docker
• Kubernetes

Installation

1. Clone the repository

   git clone https://github.com/alejandro945/meru-infrastructure.git

2. Change directory

   cd meru-infrastructure

3. Create a user for Terraform in AWS and attach admin policies (training purposes only)

   aws iam create-user --user-name cli_terraform
   aws iam attach-user-policy --policy-arn arn:aws:iam::aws:policy/AdministratorAccess --user-name cli_terraform
   aws iam create-access-key --user-name cli_terraform

   
4. Run the following commands to create the infrastructure

   aws configure
   cd iac
   terraform init
   terraform apply -auto-approve

   
5. To deploy the application in eks cluster

   aws eks --region us-east-1 update-kubeconfig --name meru-cluster
   # Ensure your user is attach in the access entries of the cluster with admin cluster policy
   kubectl get nodes -- Test the connection
   cd orchestation
   kubectl create namespace meru && helm upgrade --install meru-app ./compute -n meru && kubectl apply -f nginx.yaml -n meru

   
6. To access the application

   kubectl get svc -n meru
   # Copy the external ip and paste in the browser

   
7. To destroy the infrastructure

   terraform destroy -auto-approve

   

Tasks

1. Infrastructure Approvisioning using Terraform in AWS ✅

• Using Terraform, create an environment on AWS that includes:

  • An EC2 instance running Linux ubuntu. ✅
  • A Security Group that allows SSH (port 22) and HTTP (port 80) access. ✅
  • A public IP address assigned to the EC2 instance. ✅

• Make sure that the Terraform configuration file is modular and can be reused to deploy multiple instances. to deploy multiple instances. ✅

2. Containerization and Deployment ✅

• Create an optimized production Dockerfile that builds a Docker image for a simple web application (Node.js web application using nest framework, for example). ✅

• The Docker image should expose the application on port 80. ✅

• Create a docker-compose.yml file that allows the application to run in a container ✅

3. Kubernetes Container Deployment ✅

• Create a Kubernetes manifest (deployment.yml) that deploys the Dockerized application to a Kubernetes cluster. ✅

• Configure a LoadBalancer Service that exposes the application on a port accessible from outside the cluster. ✅

4. Linux Network and Security Configuration ✅

• On the EC2 instance created in Task 1, perform the following configurations:

  • Configure firewall rules (using iptables or ufw) to ensure that only traffic on ports 22 and 80 is allowed. traffic is only allowed on ports 22 and 80. ✅

  • Configure SSH to allow access with SSH keys only and disable password authentication. ✅

  • Install and configure Nginx as a reverse proxy that redirects HTTP traffic to port 80 of the web application inside the Docker container. ✅
