听起来您已经想出了如何将YAML文件反序列化为Kubernetes runtime.Object，但是问题是动态部署runtime.Object而没有为每种类型编写特殊代码。

kubectl通过直接与REST API进行交互来实现。具体来说，通过resource.Helper。

在我的代码中，我有类似的东西：

import (
    meta "k8s.io/apimachinery/pkg/api/meta"
    "k8s.io/cli-runtime/pkg/resource"
    "k8s.io/client-go/kubernetes"
    "k8s.io/client-go/rest"
    "k8s.io/client-go/restmapper"
    "k8s.io/apimachinery/pkg/runtime"
)

func createObject(kubeClientset kubernetes.Interface,restConfig rest.Config,obj runtime.Object) error {
    // Create a REST mapper that tracks information about the available resources in the cluster.
    groupResources,err := restmapper.GetAPIGroupResources(kubeClientset.Discovery())
    if err != nil {
        return err
    }
    rm := restmapper.NewDiscoveryRESTMapper(groupResources)

    // Get some metadata needed to make the REST request.
    gvk := obj.GetObjectKind().GroupVersionKind()
    gk := schema.GroupKind{Group: gvk.Group,Kind: gvk.Kind}
    mapping,err := rm.RESTMapping(gk,gvk.Version)
    if err != nil {
        return err
    }

    name,err := meta.NewAccessor().Name(obj)
    if err != nil {
        return err
    }

    // Create a client specifically for creating the object.
    restClient,err := newRestClient(restConfig,mapping.GroupVersionKind.GroupVersion())
    if err != nil {
        return err
    }

    // Use the REST helper to create the object in the "default" namespace.
    restHelper := resource.NewHelper(restClient,mapping)
    return restHelper.Create("default",false,obj,&metav1.CreateOptions{})
}

func newRestClient(restConfig rest.Config,gv schema.GroupVersion) (rest.Interface,error) {
    restConfig.ContentConfig = resource.UnstructuredPlusDefaultContentConfig()
    restConfig.GroupVersion = &gv
    if len(gv.Group) == 0 {
        restConfig.APIPath = "/api"
    } else {
        restConfig.APIPath = "/apis"
    }

    return rest.RESTClientFor(&restConfig)
}

我能够在我的一个项目中实现这一点。我不得不使用 kubectl 的 apply 命令中的大部分源代码才能使其正常工作。
