About

Minimal Go Kubernetes client based on Generics

Installing

go get github.com/EmilyShepherd/k8s-client-go

Usage

import (
    "context"
    "log"
    "fmt"
    client "github.com/EmilyShepherd/k8s-client-go"
)
func main() {
	kc, err := client.NewInCluster()
	if err != nil {
		log.Fatal(err)
	}
	ctx := context.Backgroud()

	endpointsAPI := client.NewObjectAPI[corev1.Endpoints](kc)

	endpoints, err := endpointsAPI.Get(ctx, "kube-system", "kubelet", metav1.GetOptions{})
	if err != nil {
		// Handle err
		return
	}
	fmt.Printf("%+v\n", endpoints)

	events, err := endpointsAPI.Watch(ctx, "kube-system", "kubelet", metav1.ListOptions{})
	if err != nil {
		// Handle err
		return
	}
	for e := range events.ResultChan() {
		fmt.Printf("%s: %+v\n", e.Type, e.Object)
	}
}

Use cases

• Embedding in Go applications for minimal binary size overhead.
• Service discovery by listing and watching endpoints. See kuberesolver as example for gRPC client side load balancing.
