Visual for Control Plane Foundations

Program narrative

This bootcamp opens with a production-shaped lab where you provision a small HA-style control plane, capture manifests, and rehearse certificate rotation paths. You learn how admission hooks shape requests, how to read controller-manager logs when sync drifts, and how to document operational runbooks your teammates can reuse. The week closes with a tabletop incident where one control plane node misbehaves and you isolate the fault using only kubectl, journal units, and etcd metrics.

Inclusions

  • apiserver flags, secure ports, and aggregation layers
  • etcd member health, defragmentation planning, and backup drills
  • Scheduler predicates, priorities, and debugging pending pods
  • Cloud controller touchpoints without vendor lock-in storytelling
  • Quality standards checklists for change windows
  • Handoffs to platform teams with crisp evidence bundles

Outcomes you can evidence

  • Produce a stamped runbook for a control plane change
  • Restore etcd from snapshot into an isolated namespace rehearsal
  • Explain scheduler decisions with events and metrics in plain language

Common questions

No. Labs run on shared cloud capacity we operate. You receive credentials and teardown rules; bring your own editor and SSH client only.

From our cohorts

“The admission control lab finally made mutating webhooks feel predictable. I still reuse the worksheet from day two when onboarding interns.”

“Dense mornings, but the etcd backup drill was the first time I trusted my own restore notes.”
