  "github_readme_excerpt": "# kustomize\n\n`kustomize` lets you customize raw, template-free YAML\nfiles for multiple purposes, leaving the original YAML\nuntouched and usable as is.\n\n`kustomize` targets kubernetes; it understands and can\npatch [kubernetes style] API objects.  It\u0027s like\n[`make`], in that what it does is declared in a file,\nand it\u0027s like [`sed`], in that it emits edited text.\n\nThis tool is sponsored by [sig-cli] ([KEP]).\n\n - [Installation instructions](https://kubectl.docs.kubernetes.io/installation/kustomize/)\n - [General documentation](https://kubectl.docs.kubernetes.io/references/kustomize/)\n - [Examples](examples)\n\n[![Build Status](https://prow.k8s.io/badge.svg?jobs=kustomize-presubmit-master)](https://prow.k8s.io/job-history/kubernetes-jenkins/pr-logs/directory/kustomize-presubmit-master)\n[![Go Report Card](https://goreportcard.com/badge/github.com/kubernetes-sigs/kustomize)](https://goreportcard.com/report/github.com/kubernetes-sigs/kustomize)\n\n## kubectl integration\n\nTo find the kustomize version embedded in recent versions of kubectl, run `kubectl version`:\n\n```sh\n\u003e kubectl version --client\nClient Version: v1.31.0\nKustomize Version: v5.4.2\n```\n\nThe kustomize build flow at [v2.0.3] was added\nto [kubectl v1.14][kubectl announcement].  The kustomize\nflow in kubectl remained frozen at v2.0.3 until kubectl v1.21,\nwhich [updated it to v4.0.5][kust-in-kubectl update]. It will\nbe updated on a regular basis going forward, and such updates\nwill be reflected in the Kubernetes release notes.\n\n| Kubectl version | Kustomize version |\n| --------------- | ----------------- |\n| \u003c v1.14         | n/a               |\n| v1.14-v1.20     | v2.0.3            |\n| v1.21           | v4.0.5            |\n| v1.22           | v4.2.0            |\n| v1.23           | v4.4.1            |\n| v1.24           | v4.5.4            |\n| v1.25           | v4.5.7            |\n| v1.26           | v4.5.7            |\n| v1.27           | v5.0.1            |\n\n[v2.0.3]: https://github.com/kubernetes-sigs/kustomize/releas",
