After delete pod, multiple pods create automatically

Question

After delete pod, multiple pods create automatically.

Answer 1

Hi Pratyush

Thanks for using QandA platform.

When you delete a pod and multiple pods are automatically created, this typically indicates that the pod is managed by a higher-level Kubernetes controller, such as a:

Deployment, ReplicaSet, StatefulSet, DaemonSet, or Job.

The above controllers are designed to maintain a desired state. So when you manually delete a pod, the controller detects the change and re-creates it, or even multiple pods, depending on the configuration.

Check what's creating the pods by running:

kubectl get pod <pod-name> -o yaml

Look for what tells you which controller owns the pod:

apiVersion: apps/v1
kind: ReplicaSet
metadata:
  name: frontend
  labels:
    app: guestbook
    tier: frontend
spec:
  # modify replicas according to your case
  replicas: 3
  selector:
    matchLabels:
      tier: frontend

Find Doc: https://kubernetes.io/docs/concepts/workloads/controllers/replicaset/

If you want to stop pods from being recreated:

kubectl scale deployment myapp-deployment --replicas=0
