GitLessOps Release Agent — AI-Driven Infrastructure Automation Platform
Completed: January 2026

Successfully completed a 2-week intensive hackathon focused on building modern Agentic AI infrastructure on Kubernetes. The project demonstrates cutting-edge approaches to cloud-native automation and AI-native architecture.

Project Overview:

• Developed Release Agent that automates application deployments through OCI image tagging, enabling GitLessOps workflow where releases are promoted via tags instead of Git commits
• Implemented voice-controlled infrastructure operations through Agent-to-Agent (A2A) protocol integration
• Built complete end-to-end automation: voice command → agent processing → OCI tagging → Flux reconciliation → deployment verification

Technical Implementation:

AI Agents & Integration:

• KAgent framework (v0.7.7) with declarative agent definitions and MCP client support
• Release Agent with skills: version validation, OCI tagging, deployment verification, status reporting
• A2A Protocol integration enabling voice-controlled infrastructure operations
• MCP (Model Context Protocol) for standardized tool integration (Flux, Kubernetes, GCP APIs)

GitLessOps Architecture:

• Flux Image Automation with OCIRepository controllers tracking dev/stable/prod tags
• OCI artifacts for Kubernetes manifests stored in Google Artifact Registry
• ImagePolicy and ImageUpdateAutomation for zero-Git deployment workflow
• Tag-based promotion: gcloud artifacts docker tags add :v1.2.3 :prod triggers automatic deployment

Infrastructure & Platform:

• Agent Gateway (KGateway v2.1.2) for security, observability, and A2A routing with experimental WebSocket support
• Full observability stack with Prometheus, Grafana, Jaeger, and Loki integrated through Gateway API
• Multi-environment deployment (dev, staging, production) with Kustomize overlays
• Workload Identity for secure authentication between Kubernetes and GCP services

DevOps & Automation:

• GitHub Actions with Workload Identity Federation for OIDC-based authentication
• Automated Docker builds and OCI manifest packaging with version pinning
• SOPS encryption with Cloud KMS for secrets management in Git
• Terraform infrastructure-as-code for complete GKE cluster and services

Deliverables:

• GitHub repository with complete source code: SuperKuberTeam
• Architecture Decision Records (ADR) documenting key design decisions
• High-Level Design (HLD) with system architecture diagrams
• Comprehensive documentation and deployment guides
• Working demo application (React + Go) deployed across three environments

Technical Stack:

• Cloud & Orchestration: GCP, GKE, Terraform, FluxCD, Kustomize, Helm
• AI & Agents: KAgent, KGateway, MCP Protocol, A2A Protocol, OpenAI
