   Leveling Up My Homelab

   A detailed account of rebuilding a personal homelab from a basic setup with limited compute and manual configuration into a production-grade Kubernetes cluster. The new infrastructure features 8 worker nodes, Talos Linux with PXE boot, GitOps via Argo CD, 10G networking, and plans for GPU workloads and multi-site clustering. The rebuild addresses previous limitations around orchestration, disaster recovery, scalability, and remote access while enabling serious experimentation with modern cloud-native technologies.

   Building a Kubernetes Platform — Think Big, Think in Planes

   Introduces a mental model for building Internal Developer Platforms by thinking in horizontal 'planes' rather than vertical layers. Explains five key planes (Developer, Integration/Delivery, Monitoring/Logging, Security, and Resource) and provides deep dives into Control, Observability, and Service planes. Uses OpenChoreo as a case study to demonstrate how this architecture enables scalable, secure-by-default platforms that centralize control while distributing scale across multiple Kubernetes clusters.

   Simplifying the Kubernetes CI/CD Pipeline

   Devtron simplifies Kubernetes CI/CD pipeline setup by providing an intuitive UI that abstracts complex YAML configurations. The platform offers Kubernetes-native builds running in pods, GitOps integration, multiple deployment strategies (rolling, blue-green, canary), and unified observability. It includes pre-built templates, multi-cluster support, security scanning, and cost management features. The guide walks through installing Devtron and creating a complete CI/CD workflow from repository connection to deployment, demonstrating how platform teams can manage builds, deployments, and operations from a single dashboard without extensive Kubernetes expertise.

   Manage Multi-Cluster Deployments with ArgoCD

   ArgoCD ApplicationSets automate Kubernetes deployments across multiple clusters using a declarative GitOps approach. The guide demonstrates how to set up ArgoCD, configure ApplicationSets with generators for multi-cluster management, and reduce deployment times by 83% while ensuring consistency. It covers installation, cluster registration, ApplicationSet configuration with parameter substitution, troubleshooting common issues, and explains how generators create parameter sets that render into individual ArgoCD Applications for each target cluster.
