A hands-on environment focused on real-world architecture and operations for cloud-native applications. This project illustrates the complete migration and scaling path of an application: starting with local containers and ending in a robust ecosystem on Kubernetes.
Modern full-stack systems require reproducible, declarative infrastructure. The challenge was transitioning an application from a local Docker Compose setup to an enterprise-grade Kubernetes cluster with automated GitOps, encrypted secrets, and high-availability storage without downtime.
Designed a progressive Infrastructure and DevOps Learning Path. It documents and automates the evolution of an application through 7 practical phases (00 to 06), moving from a simple Docker Compose setup to a complete Kubernetes cluster.
Implemented industry best practices including Infrastructure as Code with Helm, automated deployments via Argo CD (GitOps), configuration encryption with Sealed Secrets, distributed block storage with Longhorn, and advanced traffic routing using Envoy Gateway and Gateway API.
Phase 00: Local Compose. Phase 01 & 02: Kubernetes Basics & Raw YAMLs. Phase 03: Helm Package Management. Phase 04: Sealed Secrets for GitOps security. Phase 05: Longhorn Distributed Storage. Phase 06: Envoy Gateway API & Traffic Routing.
