要创建和检索自定义 Kubernetes 资源,您需要使用 RESTClient 并指定自定义资源的 API 路径和版本。
要创建自定义资源,例如 KongPlugin,可以使用以下代码:
<code class="go">import "k8s.io/client-go/rest" func CreateCustomResource() error { // Construct the full path to the custom resource absPath := "/apis/configuration.konghq.com/v1/namespaces/default/kongplugins" // Marshal the custom resource data into a byte array body, err := json.Marshal(customResource) if err != nil { return err } // Create a RESTClient using in-cluster configuration confs, err := rest.InClusterConfig() if err != nil { return err } client, err := rest.RESTClientFor(confs) if err != nil { return err } // Make a POST request to create the custom resource _, err = client.Post().AbsPath(absPath).Body(body).DoRaw() if err != nil { return err } return nil }</code>
要检索自定义资源,您可以使用以下代码:
<code class="go">import "k8s.io/client-go/rest" func GetCustomResource() (*CustomResource, error) { // Construct the full path to the custom resource absPath := "/apis/configuration.konghq.com/v1/namespaces/default/kongplugins/kongplugin-sample" // Create a RESTClient using in-cluster configuration confs, err := rest.InClusterConfig() if err != nil { return nil, err } client, err := rest.RESTClientFor(confs) if err != nil { return nil, err } // Make a GET request to retrieve the custom resource data, err := client.Get().AbsPath(absPath).DoRaw() if err != nil { return nil, err } // Unmarshal the JSON response into the custom resource object customResource := &CustomResource{} if err := json.Unmarshal(data, customResource); err != nil { return nil, err } return customResource, nil }</code>
