Delete Kubernetes PVC ebs volumes in batch

Question

I have more than 4000 pvc in my kubernetes aws eks cluster.

• From those 4000+ pvc I have to delete almost 3999 pvcs

Now instead of using command:

kubetcl delete pvc pvc-data-name

and delete every pvc separately which can take me sooo long.. I want to find a way to delete them in batches or all together.

Answer 1

you can try this one.

kubectl delete pvc --field-selector metadata.name!=<name-dont-want-to-delete-1>, metadata.name!=<name-dont-want-to-delete-2>, metadata.name!=<name-dont-want-to-delete-3>

or, also you can do this with go-client. to do this with go client see the document Ref

i have added a label in every pvc that i don't want to delete.

  labels:
    test: test-1

import (
   "context"
   "fmt"
   metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"

   "k8s.io/client-go/kubernetes"
   "k8s.io/client-go/util/homedir"
   "kmodules.xyz/client-go/tools/clientcmd"
   "log"
   "path/filepath"
)

func testFunc() ( error) {
   masterURL := ""

   kubeconfigPath := filepath.Join(homedir.HomeDir(), ".kube", "config")



   config, err := clientcmd.BuildConfigFromFlags(masterURL, kubeconfigPath)
   if err != nil {
       log.Fatalf("Could not get Kubernetes config: %s", err)
   }

   kc := kubernetes.NewForConfigOrDie(config)
   labelSelector := &metav1.LabelSelector{
       MatchExpressions: []metav1.LabelSelectorRequirement{
           {
               "test",
               metav1.LabelSelectorOpNotIn,
               []string{
                   "test-0",
                   "test-1",
               },
           },
       },
   }
   err = kc.CoreV1().PersistentVolumeClaims("default").DeleteCollection(context.TODO(), metav1.DeleteOptions{}, metav1.ListOptions{
       LabelSelector: metav1.FormatLabelSelector(labelSelector),
   })
   fmt.Println(err)
   
   return  nil
}
