CKAD — Helm & Kustomize
Helm & Kustomize
Deploying applications in Kubernetes often requires multiple YAML files — Deployments, Services, ConfigMaps, Secrets, and more. Managing these manually gets complex fast. Helm and Kustomize solve this problem in different ways.
This chapter covers the Application Deployment domain (20% of the CKAD exam). You need to know how to use Helm to install, upgrade, and rollback packages, and how to use Kustomize to patch and customize manifests.
