Kustomize

Kustomize introduces a template-free way to customize application configuration that simplifies the use of off-the-shelf applications. Now, built into kubectl as apply -k.

Kustomize traverses a Kubernetes manifest to add, remove or update configuration options without forking. It is available both as a standalone binary and as a native feature of kubectl.

• Purely declarative approach to configuration customization
• Natively built into kubectl
• Manage an arbitrary number of distinctly customized Kubernetes configurations
• Available as a standalone binary for extension and integration into other services
• Every artifact that kustomize uses is plain YAML and can be validated and processed as such
