|
|
||
| **Welcome to the Kubebuilder Roadmaps directory!** | ||
|
|
||
| This space is dedicated to housing the strategic roadmaps for the | ||
| Kubebuilder project, organized by year. Each document within this repository | ||
| outlines the key initiatives, objectives, and goals for Kubebuilder, reflecting our | ||
| commitment to enhancing the development experience within the Kubernetes ecosystem. | ||
|
|
||
| Below, you will find links to the roadmap document for each year. These documents provide insights into the | ||
| specific objectives set for the project during that time, the motivation behind each goal, and the progress | ||
| made towards achieving them: | ||
|
|
||
| - [Roadmap 2024](roadmap_2024.md) | ||
|
|
||
| ## :point_right: New plugins/RFEs to provide integrations within other Projects | ||
|
|
||
| As Kubebuilder evolves, we prioritize a focused project scope and minimal reliance on third-party dependencies, | ||
| concentrating on features that bring the most value to our community. | ||
|
|
||
| While recognizing the need for flexibility, we opt not to directly support third-party project integrations. | ||
| Instead, we've enhanced Kubebuilder as a library, enabling any project to create compatible plugins. | ||
| This approach delegates maintenance to those with the deepest understanding of their projects, fostering higher | ||
| quality and community contributions. | ||
|
|
||
| We're here to support you in developing your own Kubebuilder plugins. | ||
| For guidance on [Creating Your own plugins](https://kubebuilder.io/plugins/creating-plugins). | ||
|
|
||
| This strategy empowers our users and contributors to innovate, | ||
| keeping Kubebuilder streamlined and focused on essential Kubernetes development functionalities. | ||
|
|
||
| **Therefore, our primary objective remains to offer a CLI tool that assists users in developing | ||
| solutions for deployment and distribution on Kubernetes clusters using Golang. | ||
| We aim to simplify the complexities involved and speed up the development process, | ||
| thereby lowering the learning curve.** | ||

| # Kubebuilder Project Roadmap 2024 | ||
|
|
||
| ### **(Major Release for Kubebuilder CLI 4.x)** Removing Deprecated Plugins for Enhanced Maintainability and User Experience | ||
|
|
||
| **Status:** :construction: Work in Progress | ||
|
|
||
| **Objective:** To remove all deprecated plugins from Kubebuilder to improve project maintainability and | ||
| enhance user experience. This initiative also includes updating the project documentation to provide clear | ||
| and concise information, eliminating any confusion for users. | ||
|
|
||
| **Motivation:** By focusing on removing deprecated plugins—specifically, versions or kinds that can no | ||
| longer be supported—we aim to streamline the development process and ensure a higher quality user experience. | ||
| Clear and updated documentation will further assist in making development workflows more efficient and less prone to errors. | ||
|
|
||
| **More Info:** [GitHub Discussion #3622](https://github.com/kubernetes-sigs/kubebuilder/discussions/3622) | ||
|

| ### Proposal Pending: Seeking Contributions for kube-rbac-proxy's Role in Default Scaffold | ||
|
|
||
| **Status:** :raised_hands: Open for Discussion/Proposal Pending; Contributions Welcome | ||
|
|
||
| **Objective:** Evaluate potential modifications or the exclusion of [kube-rbac-proxy](https://github.com/brancz/kube-rbac-proxy) | ||
| from the default Kubebuilder scaffold in response to deprecations and evolving user requirements. | ||
|
|
||
| **Context:** [kube-rbac-proxy](https://github.com/brancz/kube-rbac-proxy) , a key component for securing Kubebuilder-generated projects, | ||
| faces significant deprecations that impact automatic certificate generation. | ||
| For more insights into these challenges, see [Issue #3524](https://github.com/kubernetes-sigs/kubebuilder/issues/3524). | ||
|
|
||
| This situation necessitates a reevaluation of its inclusion and potentially prompts users to | ||
| adopt alternatives like cert-manager by default. Additionally, the requirement to manually rebuild | ||
| [kube-rbac-proxy images—due](https://github.com/kubernetes-sigs/kubebuilder/blob/master/RELEASE.md#to-build-the-kube-rbac-proxy-images) | ||
| to its external status from Kubernetes-SIG—places a considerable maintenance | ||
| burden on Kubebuilder maintainers. | ||
|
|
||
| **Motivations:** | ||
| - Address kube-rbac-proxy breaking changes/deprecations. | ||
| - For further information: [Issue #3524 - kube-rbac-proxy warn about deprecation and future breaking changes](https://github.com/kubernetes-sigs/kubebuilder/issues/3524) | ||
| - Feedback from the community has highlighted a preference for cert-manager's default integration, aiming security with Prometheus and metrics. | ||
| - More info: [GitHub Issue #3524 - Improve scaffolding of ServiceMonitor](https://github.com/kubernetes-sigs/kubebuilder/issues/3657) | ||
| - Desire for kube-rbac-proxy to be optional, citing its prescriptive nature. | ||
| - See: [Issue #3482 - The kube-rbac-proxy is too opinionated to be opt-out.](https://github.com/kubernetes-sigs/kubebuilder/issues/3482) | ||
| - Reduce the maintainability effort to generate the images used by Kubebuilder projects and dependency within third-party solutions. | ||
| - Related issues: | ||
| - [Issue #1885 - use a NetworkPolicy instead of kube-rbac-proxy](https://github.com/kubernetes-sigs/kubebuilder/issues/1885) | ||
| - [Issue #3230 - Migrate away from google.com gcp project kubebuilder](https://github.com/kubernetes-sigs/kubebuilder/issues/3230) | ||
|
|
||
| **Proposed Solutions:** | ||
|
|
||
| - **Making kube-rbac-proxy Optional:** Offering users the option to include kube-rbac-proxy caters to diverse project | ||
| requirements and simplifies the transition towards its potential externalization or removal, | ||
| reducing future maintenance efforts. | ||
|
|
||
| - **Leveraging NetworkPolicies:** This alternative focuses on minimizing external dependencies by | ||
| utilizing Kubernetes-native solutions like NetworkPolicies, in line with our maintenance reduction goals. | ||
|
|
||
| - **Default Enablement of cert-manager:** While not directly addressing the maintenance concerns related to | ||
| kube-rbac-proxy, defaulting to cert-manager responds to community feedback and navigates the upcoming deprecations. | ||
| This strategy also acknowledges cert-manager's existing role as a prerequisite for webhooks. | ||
|
|
||

| ### Transition from Google Cloud Platform (GCP) | ||
|
|
||
| **Status:** :construction: In Progress / (Blocker due challenges faced) | ||
|
|
||
| **Objective:** Shift Kubernetes (k8s) project infrastructure from GCP to shared infrastructures, addressing the need | ||
| for image re-tagging and rebuilding without GCP reliance. Move away from the registry `k8s.gcr.io` to `registry.k8s.io`. | ||
|
|
||
| **Context:** The initiative to move away from GCP aligns with the broader k8s project's | ||
| goal of utilizing shared infrastructures. This transition is crucial for enhancing | ||
| collaboration and reducing dependencies on specific cloud providers. | ||
| [Issue #2647](https://github.com/kubernetes/k8s.io/issues/2647) provides more details on the move. | ||
|
|
||
| Currently, Google Cloud is used only: | ||
|
|
||
| - **(Need A)Rebuild and provide the images for kube-rbac-proxy:** | ||
|
|
||
| A particular challenge has been the necessity to rebuild images for the | ||
| [kube-rbac-proxy](https://github.com/brancz/kube-rbac-proxy), which is in the process of being | ||
| donated to kubernetes-sig. This transition was expected to eliminate the need for | ||
| continuous re-tagging and rebuilding of its images to ensure their availability to users. | ||
| The configuration for building these images is outlined | ||
| [here](https://github.com/kubernetes-sigs/kubebuilder/blob/master/RELEASE.md#to-build-the-kube-rbac-proxy-images). | ||
|
|
||
| - **(Need B) Build and Promote EnvTest binaries**: | ||
|
|
||
| The development of Kubebuilder Tools and EnvTest binaries, | ||
| essential for controller tests, represents another area reliant on k8s binaries | ||
| traditionally built within GCP environments. Our documentation on building these artifacts is | ||
| available [here](https://github.com/kubernetes-sigs/kubebuilder/blob/master/RELEASE.md#to-build-the-kubebuilder-tools-artifacts-required-to-use-env-test). | ||
|
|
||
| **Challenges/Actions and Status:** | ||
| - **kube-rbac-proxy Images:** **(Blocked)** Ensuring images are available to users while moving away from GCP. We've been implementing a new recipe for non-GCP image pushing [seen here](https://github.com/kubernetes/test-infra/blob/master/config/jobs/image-pushing/k8s-staging-kubebuilder.yaml). However, we confirmed that does not work because the project is outside from Kubernets-Sig org. | ||
| - **EnvTest binaries:** We seek assistance from k8s-infra to know how we could use this shared infrastructures to build those. Maybe an alternative option is to use go-releaser and publish the artifacts via GitHub. | ||
|

| ### Providing Helpers for Project Distribution | ||
|
|
||
| #### Distribution via Kustomize | ||
|
|
||
| **Status:** :white_check_mark: Complete | ||
|
|
||
| As of release ([v3.14.0](https://github.com/kubernetes-sigs/kubebuilder/releases/tag/v3.14.0)), | ||
| Kubebuilder includes enhanced support for project distribution. | ||
| Users can now scaffold projects with a `build-installer` makefile target. | ||
| This improvement enables the straightforward deployment of solutions directly to Kubernetes clusters. | ||
| Users can deploy their projects using commands like: | ||
|
|
||
| ```shell | ||
| kubectl apply -f https://raw.githubusercontent.com/<org>/my-project/<tag or branch>/dist/install.yaml | ||
| ``` | ||
|
|
||
| This enhancement streamlines the process of getting Kubebuilder projects running on clusters, providing a seamless deployment experience. | ||
|
|
||
| #### (New Optional Plugin) Helm Chart Packaging | ||
|
|
||
| **Status:** :raised_hands: Proposal in Progress; Seeking Contributions | ||
|
|
||
| **Objective:** We aim to introduce a new plugin for Kubebuilder that packages projects as Helm charts, | ||
| facilitating easier distribution and integration of solutions within the Kubernetes ecosystem. | ||
|
|
||
| **Motivation:** The growth of the Kubernetes ecosystem underscores the need for flexible and | ||
| accessible distribution methods. A Helm chart packaging plugin would simplify the distribution of the solutions | ||
| and allow easily integrations with common applications used by administrators. | ||
|
|
||
| **More Info:** For details on this proposal and how to contribute, | ||
| see [GitHub Pull Request #3632](https://github.com/kubernetes-sigs/kubebuilder/pull/3632). | ||

| ### Updating Scaffolding to Align with the Latest changes of controller-runtime | ||
|
|
||
| **Status:** :raised_hands: Seeking help from the contributors | ||
|
|
||
| **Objective:** Update Kubebuilder's controller scaffolding to align with the latest changes | ||
| in controller-runtime, focusing on compatibility and addressing recent updates and deprecations | ||
| related to webhooks. | ||
|
|
||
| **Context:** Kubebuilder's plugin system is designed for stability, yet it depends on controller-runtime, | ||
| which is evolving rapidly with versions still under 1.0.0. Notable changes and deprecations, | ||
| especially around webhooks, necessitate Kubebuilder's alignment with the latest practices | ||
| and functionalities of controller-runtime. We need update the Kubebuilder scaffolding, | ||
| samples, and documentation. | ||
|
|
||
| **References:** | ||
| - [Issue - Deprecations in Controller-Runtime and Impact on Webhooks](https://github.com/kubernetes-sigs/kubebuilder/issues/3721) - An issue detailing the deprecations in controller-runtime that affect Kubebuilder's approach to webhooks. | ||
| - [PR - Update to Align with Latest Controller-Runtime Webhook Interface](https://github.com/kubernetes-sigs/kubebuilder/pull/3399) - A pull request aimed at updating Kubebuilder to match controller-runtime's latest webhook interface. | ||
| - [PR - Enhancements to Controller Scaffolding for Upcoming Controller-Runtime Changes](https://github.com/kubernetes-sigs/kubebuilder/pull/3723) - A pull request proposing enhancements to Kubebuilder's controller scaffolding in anticipation of upcoming changes in controller-runtime. | ||
|
|
||
| **We encourage the Kubebuilder community to participate in this discussion, offering feedback and contributing ideas | ||
| to refine these proposals. Your involvement is crucial in shaping the future of secure and efficient project scaffolding in Kubebuilder.** |
