kubebuilder提供的Makefile将构建和部署工作大幅度简化，执行以下命令会将最新构建的CRD部署在kubernetes上
# make install ...... customresourcedefinition.apiextensions.k8s.io/applications.apps.zise.feizhu created 编译和运行controller以体验基本流程为主，不深入研究源码，所以对代码仅做少量修改，用于验证是否能生效
main.go
./controllers/application_controller.go
type ApplicationReconciler struct { client.Client Log logr.Logger Scheme *runtime.Scheme } func (r *ApplicationReconciler) Reconcile(ctx context.Context, req ctrl.Request) (ctrl.Result, error) { _ = log.FromContext(ctx) _ = r.Log.WithValues("application",req.NamespacedName) // your logic here r.Log.Info("1. %v",req) // 打印入参 r.Log.Info("2. %s",debug.Stack()) // 打印堆栈 return ctrl.Result{}, nil } ...执行以下命令，会编译并启动刚才修改的controller：
# make run /Users/zisefeizhu/linkun/goproject/kubedev/bin/controller-gen "crd:trivialVersions=true,preserveUnknownFields=false" rbac:roleName=manager-role webhook paths="./..." output:crd:artifacts:config=config/crd/bases main.go:35:2: package kubedev/controllers imports github.com/go-logr/logr from implicitly required module; to add missing requirements, run: go get github.com/go-logr/logr@v0.3.0 Error: not all generators ran successfully run `controller-gen crd:trivialVersions=true,preserveUnknownFields=false rbac:roleName=manager-role webhook paths=./... output:crd:artifacts:config=config/crd/bases -w` to see all available markers, or `controller-gen crd:trivialVersions=true,preserveUnknownFields=false rbac:roleName=manager-role webhook paths=./... output:crd:artifacts:config=config/crd/bases -h` for usage make: *** [manifests] Error 1 # go get github.com/go-logr/logr@v0.3.0 # make run 创建Application资源的实例现在kubernetes已经部署了Application类型的CRD，而且对应的controller也已正在运行中，可以尝试创建Application类型的实例了(相当于有了pod的定义后，才可以创建pod)；
kubebuilder已经自动创建了一个类型的部署文件 ./config/samples/apps_v1_application.yaml ，内容如下，很简单，接下来就用这个文件来创建Application实例：
