AWS EKS Reference Architecture

Terraform

Layered Terraform 1.5+ blueprint delivering VPC, EKS control plane, data plane, and workloads with prefix delegation to break past pod IP limits. Designed for repeatable deployments across dev, UAT, and production.

  • • 4-layer state isolation improves team velocity
  • • Prefix delegation + custom networking for 250+ pods per node
  • • Deployment orchestrated with `deploy.sh` for environment parity
GitHub Architecture notes

Jenkins Cloud Native

Helm

Helm chart that runs Jenkins with ephemeral Kubernetes agents so CI pipelines scale based on workload demand. Includes opinionated values for cloud-networked masters, persistent storage, and autoscaling node pools.

  • • Master/agent separation with dynamic Pod templates
  • • Cloud-native defaults for RBAC, ingress, and storage classes
  • • Ready for GitOps adoption via Helmfile or Argo CD
GitHub Chart values

OSSB — Slim Builder

Research

Proof-of-concept single-binary container builder inspired by BuildKit with pluggable frontends and rootless execution. Demonstrates how to simplify image assembly while keeping content-addressable caching.

  • • Full Dockerfile parser and dependency graph solver
  • • Rootless execution with namespace isolation
  • • Extensible exporters and multi-architecture planning

eks-without-ip-limit

Terraform

Production-ready Amazon EKS reference architecture built with layered Terraform (VPC → control plane → data plane → workloads). Incorporates prefix delegation, custom VPC CNI networking, and modular state boundaries for safer team collaboration.

  • • `deploy.sh` automates environment bootstrap for dev/UAT/prod
  • • Remote state data sources chain outputs across layers
  • • Optional Cilium overlay and managed add-ons packaged in Layer 3

jenkins-cloud-native

Helm

Helm chart delivering a cloud-native Jenkins control plane with pod-based ephemeral agents. Targets teams running Kubernetes-first CI/CD with autoscaling build capacity and GitOps friendly configuration.

  • • Provides baseline values for ingress, storage classes, and RBAC
  • • Ships PodTemplate definitions for containerized build agents
  • • Designed to plug into Argo CD, Flux, or Helmfile workflows

ossb

Go

OSSB (Open Source Slim Builder) explores a single-binary alternative to BuildKit. Implements core concepts like dependency graph solving, content-addressable caching, and rootless isolation while documenting open gaps.

  • • CLI powered by Cobra with multi-architecture planning
  • • Pluggable frontends/executors/exporters for experimentation
  • • Public roadmap & LIMITATIONS.md outlining remaining work

About

OSSGenesis curates open source reference implementations so platform engineering teams can adopt proven infrastructure and operations practices without starting from scratch. We document the why, the how, and the trade-offs directly in the repositories and supporting guides.

  • • Infrastructure blueprints for AWS, Kubernetes, and Terraform
  • • Cloud-native CI/CD with Jenkins, GitOps, and automated quality gates
  • • Experimentation around container build tooling and supply chain hardening
  • • Governance artifacts: Agile frameworks, CAB integrations, service SLAs
