    Use Cases & Benefits

    • Customizes raw Kubernetes YAML configurations without templates, preserving original files for reuse.
    • Enables declarative, template-free customization of Kubernetes resources with native support for overlays and patches.
    • Use for managing environment-specific Kubernetes deployments with overlays for development, staging, and production.
    • Use for maintaining upstream Kubernetes resource bases while applying local customizations via overlays.
    • Use for generating customized Kubernetes manifests that can be directly applied with kubectl for streamlined deployment.

    Should you depend on it?

    General guidance from repository metadata, not legal advice. How we score

    From the README

    kustomize lets you customize raw, template-free YAML files for multiple purposes, leaving the original YAML untouched and usable as is.

    kustomize targets kubernetes; it understands and can patch kubernetes style API objects. It's like [make], in that what it does is declared in a file, and it's like [sed], in that it emits edited text.

    This tool is sponsored by sig-cli (KEP).

    To find the kustomize version embedded in recent versions of kubectl, run kubectl version:

    The kustomize build flow at v2.0.3 was added to kubectl v1.14. The kustomize flow in kubectl remained frozen at v2.0.3 until kubectl v1.21, which updated it to v4.0.5. It will be updated on a regular basis going forward, and such updates will be reflected in the Kubernetes release notes.

    For examples and guides for using the kubectl integration please see the kubernetes documentation.
