From your first container to production-grade Kubernetes operators in Rust. 24 hands-on master labs, 54 architectural tool deep-dives, and 340+ curated open-source tools with interactive visual diagrams. Zero paywalls, built by practitioners.
Built for the Global Community
We believe world-class Kubernetes education should be completely accessible. No paywalls, no vendor bias, and no superficial "hello world" demos.
Complex distributed systems shouldn't be black boxes. We turn etcd quorums, eBPF kernel hooks, CNI packet traversal, component threat models, and Operator reconcile loops into responsive, interactive visual mental models.
Explore visual threat model →24 battle-tested master labs covering the full CKA, CKAD, and CKS curriculum, Linux container namespaces, Kyverno policies, Argo CD GitOps, Karpenter autoscaling, and building memory-safe operators in Rust with kube-rs.
Browse all 24 labs →The definitive open-source index of cloud-native projects across 27 domains—from eBPF networking and AI model inference to cost optimization and cluster triage—complete with live GitHub star telemetry.
Search the tool stack →Comprehensive, deep-dive technical articles breaking down real-world gotchas, production YAML manifests, benchmark comparisons, and disaster recovery procedures tested against real clusters.
Read field guides →Explore cluster attack vectors, multi-engine admission policies, CIS/NIST hardening scores, MITRE ATT&CK container matrices, and incident containment runbooks in one unified studio.
Multi-sheet interactive architecture with pan, zoom, layer inspection, and instant deep-linking to defense controls.
Switch instantaneously between Kyverno v1, In-Tree CEL (ValidatingAdmissionPolicy), and OPA Gatekeeper Rego.
20 real-world checks across 5 domains. Benchmark your cluster posture and export missing policies in 1-click.
10 tactics & 28 container-specific techniques mapped to threat vectors with export to MITRE ATT&CK Navigator.
Executable shell scripts for KinD/Minikube with dual-mode exploit simulation and defensive policy validation.
Emergency operational runbooks for pod quarantine, token revocation, node evacuation, memory checkpointing, and IMDS blocking.
