🚀 DevSecOps Journal - Episode 5: Infrastructure as Code with Ansible + KVM
Taking automation to the next level! In this episode, I'm replacing shell scripts with declarative Infrastructure as Code using Ansible to manage our KVM virtual infrastructure.

🔄 The Evolution:
1️⃣ From manual shell scripts to structured Ansible playbooks
2️⃣ From hard-coded configurations to template-driven provisioning
3️⃣ From imperative commands to declarative infrastructure definitions

This transformation represents a fundamental shift in how we think about and manage our virtual environments.

👉

📋 Ansible Implementation Highlights:
✅ Templated Configuration - Using Jinja2 templates for cloud-init
✅ Idempotent Operations - Safe, repeatable playbook execution
✅ Centralized Variable Management - Clean separation of config and code
✅ Declarative Syntax - Describing the desired state, not the steps
✅ Full Lifecycle Management - From creation to destruction

The Architecture Stack:
1️⃣ Template Layer - Dynamic cloud-init configurations
2️⃣ Orchestration Layer - Ansible playbooks and roles
3️⃣ Provisioning Layer - KVM and libvirt integration
4️⃣ Verification Layer - Automated SSH connectivity testing

Why This Matters:
While shell scripts get the job done, Ansible brings:
• Auditability - Clear, readable infrastructure definitions
• Reusability - Templates and roles that scale across environments
• Maintainability - Centralized variable management
• Community - Access to thousands of pre-built modules and roles

From Scripts to Systems:
This isn't just about creating VMs - it's about establishing patterns that scale. The same principles apply whether we're managing 5 VMs or 500, on-premise or in the cloud.

🤔 How are you managing your infrastructure: scripts, configuration management, or full IaC?
