🪙 PennyWise-K8s

An automated Cloud Governance & Cost Optimization platform built inside a localized Kubernetes (KinD) environment. It tracks real-time cluster spend, flags resource inefficiencies, and triggers self-healing Ansible playbooks to optimize node allocation.

🚀 Tech Stack

• Infrastructure: KinD (Kubernetes in Docker)
• Cost Tracking: Kubecost (Simulated Cloud Pricing)
• Observability: Prometheus & Grafana
• Automation Engine: Ansible Core (Kubernetes Collections)

🏗️ Architecture Flow

1. KinD Cluster runs simulated cloud workloads.
2. Kubecost & Prometheus scrape resource usage and calculate real-time dollar waste.
3. Prometheus Alertmanager flags when efficiency falls below 50%.
4. A webhook triggers the Ansible Playbook which safely cordons and drains underutilized nodes.

🛠️ How to Setup Locally

1. Spin up the KinD Cluster

kind create cluster --config kind-config.yaml --name pennywise-cluster

# Install Prometheus & Grafana
helm install monitoring prometheus-community/kube-prometheus-stack -n monitoring --create-namespace

# Install Kubecost
helm install kubecost kubecost/cost-analyzer -n kubecost --create-namespace

# Run Playbook
cd ansible/
ansible-playbook scale_down_inefficient.yml
