🚀 Kubernetes Deployment Automation: Ansible → EKS

Automated Kubernetes deployments on Amazon EKS using Ansible, demonstrating infrastructure-as-code and cloud-native automation workflows.

---

📌 Overview

This project showcases an end-to-end Kubernetes automation setup:

• Provisioned an EKS cluster using Terraform
• Configured Ansible for local and remote execution
• Deployed a Kubernetes namespace (my-app) via playbooks
• Verified cluster connectivity and deployment using kubectl
• Deployed an NGINX application to the cluster

---

⚙️ Workflow

1. Infrastructure Provisioning

• Created EKS cluster using Terraform
• Configured networking and cluster access

2. Ansible Configuration

• Set up inventory for local and remote hosts
• Enabled Ansible to interact with Kubernetes cluster

3. Kubernetes Deployment

• Executed Ansible playbook to create namespace (my-app)
• Applied Kubernetes resources to cluster

4. Validation

• Verified namespace creation using kubectl
• Confirmed application deployment (NGINX)

---

🧰 Tech Stack

• AWS EKS (Managed Kubernetes)
• Terraform (Infrastructure as Code)
• Ansible (Automation & Orchestration)
• kubectl (Kubernetes CLI)
• DigitalOcean (Optional test hosts)

---

💡 Key Skills Demonstrated

• Writing Ansible playbooks for Kubernetes resources
• Managing kubeconfig and EKS cluster access
• Automating Kubernetes deployments
• Understanding cloud networking and API access patterns
• Integrating Terraform and Ansible workflows

---

⚠️ Challenges & Fixes

• EKS connectivity issues → Resolved private vs public API endpoint access
• SSH host key verification → Managed known_hosts for remote connections
• YAML parsing errors → Fixed formatting issues in Ansible playbooks

---

✅ Outcome

• ✔ Automated creation of Kubernetes namespace (my-app)
• ✔ Verified deployment directly in EKS cluster
• ✔ Successfully deployed NGINX application
• ✔ Established repeatable Kubernetes deployment workflow

---

🧪 Takeaway

This project demonstrates how to automate Kubernetes deployments using Ansible on top of Terraform-provisioned infrastructure. It highlights real-world challenges in cluster connectivity, configuration management, and YAML-based automation—while reinforcing best practices for reliable cloud-native deployments.
