Rbac 使用 Kubebuilder 进行规则

Question

我的问题是我正在尝试使用该unstructured.Unstructured类型来创建部署，如下所示：

// +kubebuilder:rbac:groups=stable.resource.operator.io,resources=resource,verbs=get;list;watch;create;update;patch;delete
// +kubebuilder:rbac:groups=stable.resource.operator.io,resources=resource/status,verbs=get;update;patch
// +kubebuilder:rbac:groups=apps,resources=deployments,verbs=get;list;watch;create;update;patch;delete
// +kubebuilder:rbac:groups=apps,resources=deployments/status,verbs=get;list;watch;create;update;patch;delete
func (r *ResourceReconciler) Reconcile(req ctrl.Request) (ctrl.Result, error) {

    ctx := context.Background()
    log := r.Log.WithValues("resource", req.NamespacedName)
    instance := &stablev1.Resource{}
    // your logic here

    if err := r.Get(ctx, req.NamespacedName, instance); err != nil {
        log.Error(err, "unable to fetch Resource")
        // we'll ignore not-found errors, since they can't be fixed by an immediate
        // requeue (we'll need to wait for a new notification), and we can get them
        // on deleted requests.
        return ctrl.Result{}, ignoreNotFound(err)
    }
    // your logic here
    u := &unstructured.Unstructured{}
    u.Object = map[string]interface{}{
        "name":      "name",
        "namespace": "namespace",
        "spec": map[string]interface{}{
            "replicas": 2,
            "selector": map[string]interface{}{
                "matchLabels": map[string]interface{}{
                    "foo": "bar",
                },
            },
            "template": map[string]interface{}{
                "labels": map[string]interface{}{
                    "foo": "bar",
                },
                "spec": map[string]interface{}{
                    "containers": []map[string]interface{}{
                        {
                            "name":  "nginx",
                            "image": "nginx",
                        },
                    },
                },
            },
        },
    }
    u.SetGroupVersionKind(schema.GroupVersionKind{
        Group:   "apps",
        Kind:    "Deployment",
        Version: "v1",
    })
    err = r.Create(context.Background(), u)
    log.Error(err, "unable to get object")
    log.V(1).Info("reconciling")
    return ctrl.Result{}, nil

}

我的理解是，我已经指定了 rbac 规则，我的操作员应该能够创建所述部署，但我仍然收到错误：

the server does not allow this method on the requested resource

我看到的所有示例都是基于使用实际的部署类型，我找不到任何地方有使用非结构化类型执行此操作的示例，我是否遗漏了什么？为了节省时间，我尝试过：

• 手动应用集群角色
• 给定操作员 cluster-admin
• 使用了 make run 和 make deploy （显然是在运行 make manifests 等之后..）
• 角色生成器正在工作
• 我已经开始了一个新项目，以确保我玩​​弄 env 不是原因

因此，当您定义非结构化类型时，与https://godoc.org/sigs.k8s.io/controller-runtime/pkg/client中的文档所述不同。非结构化您需要将元数据字段中的命名空间和名称设置为这样的：

u.Object = map[string]interface{}{
        "metadata": map[string]interface{}{
            "name":      "name",
            "namespace": "namespace"},
        "spec": map[string]interface{}{
            "replicas": 2,
            "selector": map[string]interface{}{
                "matchLabels": map[string]interface{}{
                    "foo": "bar",
                },
            },
            "template": map[string]interface{}{
                "labels": map[string]interface{}{
                    "foo": "bar",
                },
                "spec": map[string]interface{}{
                    "containers": []map[string]interface{}{
                        {
                            "name":  "nginx",
                            "image": "nginx",
                        },
                    },
                },
            },
        },
    }

否则，非结构化客户端会将其读取为集群范围的资源部署，而集群范围的资源部署并不存在
