Kubernetes for Linux Sysadmins — From Server to Cluster
"You don't need to start from zero. You need to evolve."
Every Kubernetes concept is taught through the lens of what you already know from Linux. No fluff — just hands-on labs.
iptables → Services, systemd → Pods, /etc/fstab → PersistentVolumes. Your Linux knowledge is your superpower.
All core labs run locally with Kind — no cloud account needed. Challenges 14 and 18–20 cover cloud and VM-based labs.
Learn by breaking things. Every challenge includes troubleshooting scenarios with deliberate bugs to diagnose and fix.
Every command and YAML manifest verified against official Kubernetes v1.36 documentation. CI validates on every commit.
No setup needed — open in GitHub Codespaces and get a full Kubernetes cluster with kubectl, Kind, Helm, and k9s ready in ~3 minutes. Free for 60h/month.
Every exam domain from all three Kubernetes certifications is covered with hands-on labs.
Validated against the official CNCF Curriculum · Practice exams at Killer.sh
Progressive difficulty — from your first container to CKA/CKAD/CKS certification readiness.
Build, run, and inspect containers — the foundation Kubernetes orchestrates.
Hand your containers to Kubernetes with YAML manifests and kubectl.
Build your own multi-node Kubernetes cluster with Kind.
Scale, update, and rollback applications with zero downtime.
ClusterIP, NodePort, DNS discovery, and NetworkPolicy.
Route external traffic with Ingress and the modern Gateway API.
PVs, PVCs, StorageClasses, StatefulSets, and the sidecar pattern.
Externalize configuration and manage sensitive data securely.
ServiceAccounts, Roles, Pod Security Admission, and SecurityContext.
HPA, VPA, KEDA — scale your workloads automatically.
Package management and environment overlays for Kubernetes.
Prometheus, Grafana, probes — the three pillars of observability.
8 broken deployments to diagnose and fix. The ultimate test.
Graduation day — deploy on AKS, EKS, or GKE.
Taints, tolerations, affinity, quotas, LimitRanges, and PodDisruptionBudgets.
Multi-stage Dockerfiles, private registries, Podman, and image security.
Blue/green, canary, recreate strategies, and API deprecation migration.
Bootstrap clusters, upgrade control planes, backup etcd, explore CRDs. Requires VMs.
CIS benchmarks, audit logging, TLS Ingress, Secrets encryption. Requires VMs.
Trivy, cosign, AppArmor, seccomp, Falco — the CKS capstone.
