# Kustomize roadmap 2022 Presented at the [January 26, 2022, SIG-CLI meeting](https://youtu.be/l2plzJ9MRlk?t=1321) kustomize maintainers: @knverey, @natasha41575 [Objective: Improve contributor community](#objective-improve-contributor-community) [Objective: Improve end-user experience](#objective-improve-end-user-experience) [Objective: Improve extension experience](#objective-improve-extension-experience) ## Objective: Improve contributor community **_WHO: End user who also contributes source code._** Top priority: - Kustomization v1 (also end-user impact) ([PROJECT](https://github.com/kubernetes-sigs/kustomize/projects/12)) - Remove the following fields: - [vars](https://github.com/kubernetes-sigs/kustomize/issues/2052) - [patchesJson6902, patchesStrategicMerge (consolidate on \`patches)](https://github.com/kubernetes-sigs/kustomize/issues/4376) - [helmChartInflationGenerator, helmCharts, helmGlobals](https://github.com/kubernetes-sigs/kustomize/issues/4401) - all long-deprecated fields in Kustomization v1 such as \`bases\` and those being accommodate by kustomize edit \[[see code snippet](https://github.com/kubernetes-sigs/kustomize/blob/ee4b7847f0beb6c0d2070673b10f23f7b3e92e82/api/types/fix.go#L15)\] - Ensure that \`kustomize edit fix\` handles migrations for all those, and that anything it changes is not still present in v1. - [Add reorder field](https://github.com/kubernetes-sigs/kustomize/issues/3913). Default should be FIFO and legacy should also be supported (could add alphabetic and custom sort support eventually). Replaces -reorder flag. - [Reconcile openapi and crds field](https://github.com/kubernetes-sigs/kustomize/issues/3944) - [Consider deprecating configurations field](https://github.com/kubernetes-sigs/kustomize/issues/3945) (old, pre-plugin, pre-openapi global configuration) - [Add a field to enable the managedby label](https://github.com/kubernetes-sigs/kustomize/issues/4047) Second priority: - Improve contributor documentation - [Instructions to upgrade kustomize-in-kubectl](https://github.com/kubernetes-sigs/kustomize/issues/3951) Also very valuable to the project: - [Improve the release process](https://github.com/kubernetes-sigs/kustomize/issues/3952) to support regular biweekly releases [PROJECT](https://github.com/kubernetes-sigs/kustomize/projects/7) - Release sigs.k8s.io/kustomize/api v1.0.0 [PROJECT](https://github.com/kubernetes-sigs/kustomize/projects/5) - [Reduce the public surface of the API module](https://github.com/kubernetes-sigs/kustomize/issues/3942) - [Vendor all transitive deps](https://github.com/kubernetes-sigs/kustomize/issues/3706). Since kustomize is in kubectl, we must do as kubectl does to manage deps, exposing new transitive deps in code review. - Project administration - [Rename master branch to main](https://github.com/kubernetes-sigs/kustomize/issues/3954) ## Objective: Improve end-user experience **_WHO: End user that wants kustomize build artifacts (binaries, containers)._** Top priorities: - Bug fixes: - Fix bugs in basic anchor support: [issue query](https://github.com/kubernetes-sigs/kustomize/issues?q=is%3Aopen+is%3Aissue+label%3Aarea%2Fanchors) - integer keys support: [#3446](https://github.com/kubernetes-sigs/kustomize/issues/3446) - kyaml not respecting \`$patch replace|retainKeys\`: [#2037](https://github.com/kubernetes-sigs/kustomize/issues/2037) - kustomize removing quotes from namespace field values: [#4146](https://github.com/kubernetes-sigs/kustomize/issues/4146) - Kustomize doesn’t support metadata.generateName: [#641](https://github.com/kubernetes-sigs/kustomize/issues/641) - Send kustomize CLI version number into kubectl ([kubectl issue](https://github.com/kubernetes/kubectl/issues/797) / [kustomize issue](https://github.com/kubernetes-sigs/kustomize/issues/1424)) - Kustomize performance investigations/improvements [PROJECT](https://github.com/kubernetes-sigs/kustomize/projects/13) - [Support generic resource references in name reference tracking](https://github.com/kubernetes-sigs/kustomize/issues/3418) - [KEP 4267: retain the resource origin and transformer data in annotations](https://github.com/kubernetes-sigs/kustomize/pull/4267) Secondary priorities: - kustomize cli v5 ([PROJECT](https://github.com/kubernetes-sigs/kustomize/projects/14)) - [Drop the --reorder flag](https://github.com/kubernetes-sigs/kustomize/issues/3947) - [Graduate cfg read-only commands out of alpha](https://github.com/kubernetes-sigs/kustomize/issues/4090). - [Drop the –enable-managedby-label](https://github.com/kubernetes-sigs/kustomize/issues/4047) - Drop old plugin-related fields in favor of [the Catalog-style fields](https://github.com/kubernetes/enhancements/tree/master/keps/sig-cli/2906-kustomize-function-catalog). - [Drop the helm flags](https://github.com/kubernetes-sigs/kustomize/issues/4401) - [Confusion around namespace replacement](https://github.com/kubernetes-sigs/kustomize/issues/880). Also very valuable to the project: - [Overinclusion of root directory error in error messages](https://github.com/kubernetes-sigs/kustomize/issues/4348) - [Add kustomize localize command](https://github.com/kubernetes-sigs/kustomize/issues/3980) - [Fix Windows support in test suite](https://github.com/kubernetes-sigs/kustomize/issues/4001) - Improve end-user documentation [PROJECT](https://github.com/kubernetes-sigs/kustomize/projects/9) ## Objective: Improve extension experience **_WHO: Plugin developers: end users who extend kustomize, but don’t think about internals._** This objective is described in detail in the [Kustomize Plugin Graduation KEP](https://github.com/kubernetes/enhancements/tree/master/keps/sig-cli/2953-kustomize-plugin-graduation) / [PROJECT](https://github.com/kubernetes-sigs/kustomize/projects/15) . Top priorities: - Fix core usability issues with KRM Function extensions: - [Better errors for function config failures](https://github.com/kubernetes-sigs/kustomize/issues/4398) - [Container KRM Mounts are not mounting via function parameters](https://github.com/kubernetes-sigs/kustomize/issues/4290) - [Resolution of local file references in extensions transformer configuration](https://github.com/kubernetes-sigs/kustomize/issues/4154) - [Do not silently ignore plugins when config has typo](https://github.com/kubernetes-sigs/kustomize/issues/4399) - [KRM Exec Function can't locate executable when referencing a base](https://github.com/kubernetes-sigs/kustomize/issues/4347) - Once core usability issues are fixed, [deprecate legacy exec and Go plugin support](https://github.com/kubernetes/enhancements/tree/master/keps/sig-cli/2953-kustomize-plugin-graduation) - [Catalog KEP](https://github.com/kubernetes/enhancements/tree/master/keps/sig-cli/2906-kustomize-function-catalog) Secondary priorities: - [Remove Starlark support](https://github.com/kubernetes-sigs/kustomize/issues/4349) - [Composition KEP](https://github.com/kubernetes/enhancements/pull/2300). The implementation is complete in [#4223](https://github.com/kubernetes-sigs/kustomize/pull/4323), but depends on: - [Convert resources and components to be backed by a reusable generator](https://github.com/kubernetes-sigs/kustomize/issues/4402) - [Enable explicitly invoked transformers to use default fieldSpecs](https://github.com/kubernetes-sigs/kustomize/issues/4404) - [Enable built-in generators to be used in the transformers field ](https://github.com/kubernetes-sigs/kustomize/issues/4403) Also very valuable to the project: - [Improve docs for kyaml libraries](https://github.com/kubernetes-sigs/kustomize/issues/3950), especially by adding examples. - [Create a reserved field for plugin runtime information](https://github.com/kubernetes-sigs/kustomize/issues/4405) - [Develop new standard process for implementing builtin transformers](https://github.com/kubernetes-sigs/kustomize/issues/4400)
