Kustomize

CKAD v1.35 · Application Deployment (20%) → "Kustomize" ALSO: CKA v1.35 · Cluster Architecture (25%) → "Use Helm and Kustomize to install cluster components" Target time: 12 minutes

A Kustomize base exists at:

scenarios/ckad/06-kustomize/base/

It defines Deployment reporter (1 replica, nginx:1.26-alpine) and a Service.

Create an overlay at:

scenarios/ckad/06-kustomize/overlays/prod/

that, WITHOUT editing any file under base/, produces:

1. everything in namespace kust
2. name prefix prod- (so the Deployment becomes prod-reporter)
3. replicas: 4
4. image tag 1.27-alpine
5. the label env=prod on every generated resource
6. a ConfigMap named reporter-settings generated from the literal TIER=gold, wired into the container as an envFrom

Then apply it: kubectl apply -k scenarios/ckad/06-kustomize/overlays/prod

The namespace kust already exists.
