https://ops.docs.72602.space/kubernetes/operator/kubebuilder/index.html Basic Kubebuilder 是一个使用 CRDs 构建 K8s API 的 SDK，主要是： 基于 controller-runtime 以及 client-go 构建 提供一套可扩展的 API 框架，方便用户从零开始开发 CRDs 和 Controllers 和 Admission Webhooks 来扩展 K8s。 还提供脚手架工具初始化 CRDs 工程，自动生成 boilerplate 模板代码和配置； Architecture Main.go import ( _ "k8s.io/client-go/plugin/pkg/client/auth" ctrl "sigs.k8s.io/controller-runtime" ) // nolint:gocyclo func main() { ... mgr, err := ctrl.NewManager(ctrl.GetConfigOrDie(), ctrl.Options{} ... if err = (&controller.GuestbookReconciler{ Client: mgr.GetClient(), Scheme: mgr.GetScheme(), }).SetupWithManager(mgr); err != nil { setupLog.Error(err, "unable to create controller", "controller", "Guestbook") os.Exit(1) } ... if os.Getenv("ENABLE_WEBHOOKS") != "false" { if err = webhookwebappv1.SetupGuestbookWebhookWithManager(mgr); err != nil { setupLog.Error(err, "unable to create webhook", "webhook", "Guestbook") os.Exit(1) } } Manager Manager是核心组件，可以协调多个控制器、处理缓存、客户端、领导选举等，来自https://github.com/kubernetes-sigs/controller-runtime/blob/v0.20.0/pkg/manager/manager.go Hugo en Thu, 07 Mar 2024 15:00:59 +0800 https://ops.docs.72602.space/kubernetes/operator/kubebuilder/startup/index.html Thu, 07 Mar 2024 15:00:59 +0800 https://ops.docs.72602.space/kubernetes/operator/kubebuilder/startup/index.html Prerequisites go version v1.23.0+ docker version 17.03+. kubectl version v1.11.3+.
