Installation
Install From Source
Step 1: Clone the repo
$ git clone https://github.com/PrasadG193/kyaml2go.git
Step 2: Build binary using make
$ make
Step 3: Convert K8s specs into Go client code
$ cat testdata/service.yaml apiVersion: v1 kind: Service metadata: name: mysql-service labels: app: mysql spec: ports: - name: server port: 8080 targetPort: 5000 protocol: TCP type: ClusterIP selector: app: mysql
$ kyaml2go create -f testdata/service.yaml // Auto-generated by kyaml2go - https://github.com/PrasadG193/kyaml2go package main import ( "fmt" corev1 "k8s.io/api/core/v1" metav1 "k8s.io/apimachinery/pkg/apis/meta/v1" "k8s.io/apimachinery/pkg/util/intstr" "k8s.io/client-go/kubernetes" "k8s.io/client-go/tools/clientcmd" "k8s.io/client-go/util/homedir" "os" "path/filepath" ) func main() { // Create client var kubeconfig string kubeconfig, ok := os.LookupEnv("KUBECONFIG") if !ok { kubeconfig = filepath.Join(homedir.HomeDir(), ".kube", "config") } config, err := clientcmd.BuildConfigFromFlags("", kubeconfig) if err != nil { panic(err) } clientset, err := kubernetes.NewForConfig(config) if err != nil { panic(err) } kubeclient := clientset.CoreV1().Services("default") // Create resource object object := &corev1.Service{ TypeMeta: metav1.TypeMeta{ Kind: "Service", APIVersion: "v1", }, ObjectMeta: metav1.ObjectMeta{ Name: "mysql-service", Labels: map[string]string{ "app": "mysql", }, }, Spec: corev1.ServiceSpec{ Ports: []corev1.ServicePort{ corev1.ServicePort{ Name: "server", Protocol: corev1.Protocol("TCP"), Port: 8080, TargetPort: intstr.IntOrString{ Type: intstr.Type(0), IntVal: 5000, }, NodePort: 0, }, }, Selector: map[string]string{ "app": "mysql", }, Type: corev1.ServiceType("ClusterIP"), HealthCheckNodePort: 0, }, } // Manage resource _, err = kubeclient.Create(object) if err != nil { panic(err) } fmt.Println("Service Created successfully!") }
