This repository documents four weeks of intense, end-to-end Kubernetes and Cloud Native operations. It serves as a practical demonstration of advanced skills in declarative infrastructure, operational resilience, and hybrid cloud management, directly confirming competencies in all respective domains.
All experiments were executed independently, resulting in a robust environment spanning Google Cloud Platform (GCP) and On-Premises Hypervisors (ProxMox/KVM).
| Pillar | Key Achievement | Demonstrated Expertise |
|---|---|---|
| Hybrid IaC | Provisioned and tore down compute resources declaratively across GCP and ProxMox using Terraform. | GCP (IAM, Billing, Secrets), ProxMox RBAC, Multi-Cloud Automation. |
| Resilience & HA | Engineered and validated self-healing application lifecycle and robust Persistent Volume (PV/PVC) storage. | Deployments (Rollbacks, Rollouts), ReplicaSets, Pod Troubleshooting, Stateful Workloads. |
| Advanced Operations | Implemented a Service Mesh (Istio) for L7 traffic control and established a comprehensive Prometheus observability stack. | Istio Gateways, Service Accounts, Certificate Management, Bash Automation. |
Detailed, timestamped documentation of all operational procedures, troubleshooting steps, and successful validations can be found in the accompanying OPERATIONS_LOG.md file.
