Kubernetes Fundamentals
Core Cluster Foundations
Install, upgrade, and observe a multi-node lab until kubectl muscle memory feels natural.
From 980,000 KRW — informational only, no checkout on this site.
Overview
Week one focuses on control plane vocabulary without drowning in slides. You bring a laptop; we provide namespaces, sample workloads, and deliberate breakages to repair. Each afternoon ends with a short retro on what slowed you down so the next lab opens cleaner.
What is included
- Hands-on cluster provisioning in shared lab tenants
- Resource model drills for pods, services, and storage classes
- NetworkPolicy sketches you can reuse at work
- Observability hooks wired into sample apps
- Incident replay cards with instructor debrief
- Printed runbook templates for change windows
- Office hours block for workplace-specific questions
Outcomes
- Explain how scheduling decisions surface in events
- Draft a sensible resource request profile for a stateless service
- Walk teammates through a safe kubectl-based health check

FAQ
Do I need prior container experience?
Yes—comfort with Dockerfiles and basic Linux networking is assumed. If you are brand new to containers, ask us for a primer list; we do not cover container basics inside this week.
Is the lab environment shared?
You receive a dedicated namespace with quotas. Some network exercises use a shared service mesh sandbox.
What is not included?
We do not sit the official exam for you, and we do not ship hardware. Enterprise data stays in your policies—no production credentials in our classroom.
Recent learner notes

The NetworkPolicy afternoon finally made taints and tolerations click because we traced a real timeout together.
-
Labs are opinionated in a good way—less YAML wallpaper, more 'why did this rollout pause?'
