Does anyone know how to delete pod from kubernetes master node? I have this one master node on bare-metal ubuntu server. When i'm trying to delete it with "kubectl delete pod .." or force deleting from there: https://kubernetes.io/docs/tasks/run-application/force-delete-stateful-set-pod/ it doesnt work. the pod is creating again and again...
The pods in a Statefulsets are managed by ReplicaSets and will be recreated again if the current and the desired replicas defined in the spec do not match.
The document you linked provides instructions as to how to kill the pods forcefully avoiding the graceful shutdown behaviour which can have unexpected behaviour depending on the application.
The link clearly states the pods will be recreated in the section:
Force deletions do not wait for confirmation from the kubelet that the Pod has been terminated. Irrespective of whether a force deletion is successful in killing a Pod, it will immediately free up the name from the apiserver. This would let the StatefulSet controller create a replacement Pod with that same identity; this can lead to the duplication of a still-running Pod, and if said Pod can still communicate with the other members of the StatefulSet, will violate the at most one semantics that StatefulSet is designed to guarantee.
If you want the pods to be stopped and new pods for the Statefulset do not get created, you need to scale down the Statefulset by changing the replicas to 0.
You can read the official docs for how to scale the Statefulset replicas.
