CKA v1.35 · Cluster Architecture, Installation and Configuration (25%) → "Use Helm and Kustomize to install cluster components" → "Understand CRDs, install and configure operators" Target time: 15 minutes
A chart lives at scenarios/cka/11-helm-crd/chart (defaults: 1 replica, nginx:1.26-alpine, tier bronze).
Part 1 — Helm
Install it as release telemetry in namespace platform (create the
namespace as part of the install), overriding:
replicaCount = 3
image.tag = 1.27-alpine
tier = gold
The release must show STATUS deployed, and the Deployment must be 3/3.
Part 2 — CRDs
Create a CustomResourceDefinition for a namespaced resource: group platform.k8s-muscle.io version v1 (served, storage) kind Probe (plural probes, shortName pr) schema spec.target (string, required), spec.intervalSeconds (integer)
Then create a Probe named heartbeat in platform with
target "https://example.com ↗" and intervalSeconds 30.
kubectl get pr -n platform must list it.
