import ( "k8s.io/kubernetes/pkg/client/unversioned" "k8s.io/kubernetes/pkg/api/v1" ) func main() { // create a client object to interact with the API server client := unversioned.NewOrDie(&unversioned.Config{ Host: "http://localhost:8080", }) // create a new secret object secret := &v1.Secret{ ObjectMeta: v1.ObjectMeta{ Name: "my-secret", Namespace: "default", }, Data: map[string][]byte{ "username": []byte("my-username"), "password": []byte("my-password"), }, } // create the secret _, err := client.Secrets("default").Create(secret) if err != nil { panic(err) } // retrieve the secret retrievedSecret, err := client.Secrets("default").Get("my-secret") if err != nil { panic(err) } // retrieve the secret data username := string(retrievedSecret.Data["username"]) password := string(retrievedSecret.Data["password"]) }In the above code example, a client object is created to interact with the Kubernetes API server. Then, a new Secret object is created with a username and password. This secret is then created in the default namespace using the Kubernetes API server. Finally, the secret is retrieved, and the username and password are extracted from the Secret's data. The `k8s.io/kubernetes/pkg/client/unversioned` package library provides methods to interact with various Kubernetes resources like Pods, Deployments, ReplicaSets, etc.
