About kustomize

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.

What's new in 5.8.3

This release eliminates dependencies and compressed blobs that were an issue when bumping kustomize-in-kubectl.
No functional changes in kustomize.
