🌱 Update test environment to Kubernetes 1.34 to match scaffolded projects

[Copilot]

make test-e2e-local fails with 404 when fetching kubebuilder-tools because the test environment was using a different Kubernetes version than the scaffolded projects.

Changes

• Update KIND_K8S_VERSION from v1.33.0 to v1.34.0 in test/common.sh to match the k8s.io/api v0.34.1 used in scaffolded projects
• Update setup-envtest from release-0.20 to release-0.22 to support Kubernetes 1.34

This ensures the e2e test environment uses the same Kubernetes version as the scaffolded projects (testdata/project-v4/go.mod), maintaining consistency across the codebase.

Version 1.34.0 is supported by controller-runtime release-0.22 and has available tooling in the setup-envtest GCS bucket.

Kubebuilder

Project Overview

Kubebuilder is a framework and command-line interface (CLI) for building Kubernetes APIs using Custom Resource Definitions (CRDs).
It provides scaffolding and abstractions that accelerate the development of controllers, webhooks, and APIs written in Go.

• GitHub: https://github.com/kubernetes-sigs/kubebuilder
• Go module: sigs.k8s.io/kubebuilder/v4 (requires Go ≥1.25)
• Core libraries: controller-runtime, controller-tools

---

Core Components

controller-runtime

• Repository: kubernetes-sigs/controller-runtime
• Purpose: Runtime building blocks for controllers.
• Capabilities:
  • Define and manage controllers and reconcilers
  • Run managers coordinating multiple controllers
  • Register and handle webhooks
  • Expose metrics and health probes

controller-tools

• Repository: kubernetes-sigs/controller-tools
• Purpose: Code and manifest generation.
• Capabilities:
  • Generate CRDs, RBAC, OpenAPI specs
  • Provide Make targets: make generate, make manifests, etc.

---

Extensibility and Integrations

• Library mode: Kubebuilder can be imported as a library by other SDKs.
• Example: Operator SDK builds on Kubebuilder for Ansible/Helm operators.
• Extension docs: docs/book/src/plugins/extending

---

Architecture

• Design: Modular, plugin-based.
• Core Plugins:
  • pkg/plugins/golang/v4 — scaffolds Go projects
  • pkg/plugins/common/kustomize/v2 — scaffolds the config/ dir using Kustomize
• Additional Plugins:
  • pkg/plugins/helm/v2-alpha — Helm-based operators
  • pkg/plugins/deploy-image — container image support
  • pkg/plugins/autoupdate/v1-alpha — upgrade automation
  • Full list under docs/book/src/plugins/available

Build & Test Commands

Build Kubebuilder

# Build local binary into ./bin/
make build

# Install into $GOBIN so `kubebuilder` is on PATH
make install

After modifying scaffolding or code generation, run:

make generate

Lint & Style Checks

# Validate and fix code style issues
make lint-fix

Testing Instructions

Pre-requisites

To run tests under test/ you need:

• Go
• Docker
• kind (Kubernetes-in-Docker)
• Kubebuilder binary built and installed locally

Cluster setup

# Install kubebuilder binary
make install

# Clean up any existing test cluster
kind delete cluster

# Create a new kind cluster
kind create cluster

Ensure kubectl config current-context points to kind-kind before running tests.

Running e2e tests

# Run all tests
go test ./test/... -v

The test suite includes both:

• Unit tests — run locally without cluster dependencies.
• **Integration / E...

• Fixes make test-e2e-local fails #4515

Hi @Copilot. Thanks for your PR.

I'm waiting for a github.com member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

1.34.0

[Copilot]

Updated to use Kubernetes 1.34.0 to match the scaffolded go.mod (k8s.io/api v0.34.1). Also updated setup-envtest to release-0.22 to support k8s 1.34. Changes verified and working. Commit: 5d547cd
