k8s delete policy

admin 11月 13, 2020 0

In k8s 1.12, the default policy for objects will be orphan. For example, the code below delete statefulset ss but leaves all pods belongs to it:

client.AppsV1beta1().StatefulSets(ss.Namespace).Delete(ss.Name, &metav1.DeleteOptions{})

We have to set PropagationPolicy explicitly to delete pods along with the statefulset.

backgroundPolicy := metav1.DeletePropagationBackground
client.AppsV1beta1().StatefulSets(ss.Namespace).Delete(ss.Name, &metav1.DeleteOptions{PropagationPolicy: &backgroundPolicy})
