README: Setting Up EKS Cluster and Applications

This README provides a step-by-step guide for setting up an Amazon EKS (Elastic Kubernetes Service) cluster and deploying various applications using Terraform. Follow the instructions below to seamlessly configure your environment.

Amazon EKS Cluster Setup

1. Navigate to the eks-setup directory:

   cd eks-setup

2. Deploy the EKS cluster:

   terraform init
   terraform apply

3. Connect to the EKS cluster:

   aws eks update-kubeconfig --region us-east-1 --name eks-cluster-traking-project

ArgoCD Setup

1. Navigate to the ArgoCD setup directory:

   cd ../argo-cd-setup

2. Deploy ArgoCD:

   terraform init
   terraform apply

3. Port-forward the ArgoCD service:

   kubectl port-forward svc/argocd-server -n argocd 8080:443

4. Fetch and decrypt the password to connect to the ArgoCD server:

   kubectl get secrets argocd-initial-admin-secret -o yaml -n argocd | grep password: | sed 's#.*password: ##g' | base64 -d

5. Deploy the configurations in ArgoCD. Create a new app and paste the YAML configuration provided.

apiVersion: argoproj.io/v1alpha1 kind: Application metadata: name: mahat spec: destination: name: '' namespace: project server: 'https://kubernetes.default.svc' source: path: . repoURL: 'https://github.com/ZivAmram/mahat-project-configs.git' targetRevision: HEAD sources: [] project: default syncPolicy: automated: prune: true selfHeal: true syncOptions: - CreateNamespace=true - ServerSideApply=true - ApplyOutOfSyncOnly=true syncInterval: 3m # Set the sync interval to 3 minutes

Prometheus Setup

1. Navigate to the prometheus-setup directory:

   cd ../prometheus-setup

2. Deploy Prometheus:

   terraform init
   terraform apply

3. Port-forward the Prometheus service:

   kubectl port-forward svc/prometheus-operated -n monitoring 9090:9090

• Port-forward Grafana service:

  kubectl port-forward svc/kube-prometheus-stackr-grafana 3000:80 -n monitoring

  • Username: admin
  • Password: prom-operator

• Port-forward the app and mongo services:

  kubectl port-forward svc/trading-app-svc 5000:8080 -n project
  kubectl port-forward svc/mongo 27017:27017 -n project

Additional Steps (Optional)

• To view the cluster in the AWS website, apply the view-pods-role.yaml file:

  kubectl apply -f view-pods-role.yaml

Destroy

1. On the AWS console, delete the load balancer and the S3 bucket that contains the Terraform state.

2. Navigate to the eks-setup directory:

   cd eks-setup

3. Destroy the EKS cluster:

   terraform destroy

Follow these instructions carefully to ensure a smooth setup and teardown process for your EKS cluster and associated applications.
