Migrate from Docker Compose to Helm without throwing away your Compose setup. Use kompose, hybrid CI stages, and run both in parallel during the transition.

Traefik, ingress-nginx, or HAProxy on k3s? ingress-nginx retired in March 2026. Install commands, IngressRoute vs Ingress, and the ServiceLB port trap.

etcd snapshots and Velero on k3s: the native S3 upload flags, the local-path hostPath trap that silently skips your PV data, and a restore drill that works.

Give your bare-metal Kubernetes cluster load-balanced services with MetalLB. Layer 2, BGP, IPAddressPools, and when to use each.

Longhorn is opinionated and simple. OpenEBS is modular with more levers. How the two storage drivers differ on architecture and speed for a 3-node k3s.

ArgoCD runs GitOps on k3s: install it, lay out the repo, and manage apps declaratively from Git. Covers sealed-secrets, sync waves, and app-of-apps.

Master Helm templating sanity. Values files, smart defaults, when to skip Helm entirely, and why nested variables aren't always the answer.

Build a three node Kubernetes cluster on mini PCs with k3s: static IPs, firewall ports, local-path storage, and a first deployment that actually answers.

Vector vs Fluent Bit log shippers: Rust-based transforms and sinks vs lightweight C agent. Config, VRL, footprint, and when each wins.

Daemonless OCI image builds in CI without Docker-in-Docker risks. Kaniko vs Buildah compared, when each fits, and which one suits your pipeline.

ArgoCD ApplicationSets let one template generate dozens of GitOps Applications across clusters. Covers List, Cluster, Git, Matrix, and PR generators with real patterns.

OPA and Rego aren't just Kubernetes gatekeepers. Block :latest tags in CI, enforce Terraform resource tags, and filter HTTP APIs.
