In Kubernetes, you can define and manage custom resources, which extend the capabilities of the platform. Creating and getting custom resources can be done programmatically using the Go client library.
To create a custom resource such as the KongPlugin, you'll need to use the RESTClient of the Kubernetes clientset. Here's how:
<code class="go">// Create a KongPlugin custom resource. kongPlugin := &KongPlugin{ TypeMeta: metav1.TypeMeta{ APIVersion: "configuration.konghq.com/v1", Kind: "KongPlugin", }, ObjectMeta: metav1.ObjectMeta{ Name: "add-response-header", }, Config: KongPluginConfig{ Add: KongPluginConfigAdd{ Headers: []string{"demo: injected-by-kong"}, }, }, Plugin: "response-transformer", } body, err := json.Marshal(kongPlugin) if err != nil { panic(err) } data, err := clientset.RESTClient(). Post(). AbsPath("/apis/configuration.konghq.com/v1/namespaces/" + namespace + "/kongplugins"). Body(body). DoRaw(context.TODO())</code>
To retrieve a custom resource, you can use the Get() method of the RESTClient:
<code class="go">// Get the KongPlugin custom resource. data, err := clientset.RESTClient(). Get(). AbsPath("/apis/configuration.konghq.com/v1/namespaces/" + namespace + "/kongplugins/add-response-header"). DoRaw(context.TODO())</code>
