End-to-end-DevOps | Go Application

This repository contains scripts and Kubernetes manifests for deploying the Go application on an AWS EKS cluster with an accompanying ECR repository and EBS volumes. The deployment includes setting up an Ingress controller, monitoring with Prometheus and Grafana, and a continuous deployment pipeline.

Before you run the script

Update Script Variables:

The build.sh script contains a set of variables that you need to customize according to your AWS environment and deployment requirements. Here's how you can update them:

1. Open the build.sh script in a text editor of your choice.

2. Update the variables at the top of the script with your specific configurations:

   cluster_name="YOUR_EKS_CLUSTER_NAME"
   region="YOUR_AWS_REGION"
   aws_id="YOUR_AWS_ACCOUNT_ID"
   repo_name="YOUR_REPO_NAME"
   domain="YOUR_DOMAIN.com"
   namespace="go-survey"

3. Save the changes to the build.sh script.

Update application domain

1. Navigate to terraform/monitoring.tf
2. Update applications host with your domain
3. Do the same in k8s/app.yaml

    grafana:
      adminUser: admin
      adminPassword: admin
      enabled: true
      ingress:
        enabled: true
        ingressClassName: nginx
        annotations:
          cert-manager.io/cluster-issuer: letsencrypt-production
        hosts:
          - grafana.[YOUR_DOMAIN]
        tls:
          - secretName: grafana-tls
            hosts:
              - grafana.[YOUR_DOMAIN]

IMPORTANT: Ensure you have updated the domain for all the services, Grafana, Alertmanager and Prometheus

How to Run

1. Clone the repository and navigate to the root directory.

2. Make the deployment script executable:

   chmod +x build.sh

3. Run the deployment script:

   ./build.sh

4. Follow the post-deployment steps printed by the script to update your DNS records with the provided Ingress URL.
