Kustomize Intermediate
Kustomize is a template-free Kubernetes configuration management tool that enables DevOps engineers and platform teams to customize, compose, and deploy application manifests across environments without duplication. Adopted in kubectl since v1.14, Kustomize eliminates the need for templating tools by using overlays and patches, improving deployment safety and auditability. Over 83% of Certified Kubernetes Administrators (CKA) report using Kustomize daily, reflecting its critical role in modern cloud-native workflows.
This course prepares learners for the Linux Foundation’s Certified Kubernetes Administrator (CKA) certification, where Kustomize is a tested competency. Koenig Solutions provides official vendor-authorized courseware, 30-day lab access, and Guaranteed-to-Run live training, empowering professionals to master declarative configuration and advance into senior DevOps and platform engineering roles.

Course Overview
The Kustomize course by Open Source is designed for DevOps engineers, Kubernetes administrators, and cloud application developers seeking to master template-free configuration management in Kubernetes environments. While there is no standalone Kustomize certification, this training directly supports preparation for the Certified Kubernetes Application Developer (CKAD) exam, a key credential in the cloud-native ecosystem. With Kubernetes adoption growing by 83% over recent years according to the Cloud Native Computing Foundation, organizations increasingly demand professionals skilled in declarative configuration tools like Kustomize to manage complex deployments efficiently and avoid manifest duplication.
This course covers core Kustomize functionalities including bases and overlays, transformers, patches (StrategicMerge and Json6902), ConfigMap and Secret generators, and component composition—all using plain YAML without templating. Students engage in hands-on labs within a dedicated cloud environment where they build real-world projects such as deploying a single application across development, staging, and production environments using overlay patterns. Using official tooling integrated into kubectl (v1.14+), learners configure cross-cutting fields, manage environment-specific customizations, and validate outputs with `kubectl kustomize` and `kubectl diff`, ensuring mastery of GitOps-aligned workflows that maintain auditable, reproducible deployments.
By completing this Kustomize training, participants strengthen their readiness for the CKAD certification, which is globally recognized and associated with a 15–22% salary premium over non-certified peers, with typical U.S. base salaries ranging from $115,000 to $160,000. Koenig Solutions enhances this learning experience with Guaranteed-to-Run public schedules and optional 1-on-1 instruction, ensuring personalized support and flexibility. Graduates gain not only technical proficiency but also a competitive edge in the job market, positioning themselves for advanced roles in cloud-native development and infrastructure management.
