In Kubernetes statefulset, ordinal number starts with 0 --> N. Is there any way that starting ordinal number can be set to custom number.
redis-cluster-10 1/1 Running 0 12h
redis-cluster-11 1/1 Running 2 17h
redis-cluster-12 1/1 Running 0 17h
redis-cluster-13 1/1 Running 0 17h
redis-cluster-14 1/1 Running 2 17h
redis-cluster-15 1/1 Running 0 17h
no. it is not supported out of box.you might have to customize the statefulset controller.
I think this is the part that might be of interest to you:
// getParentNameAndOrdinal gets the name of pod's parent StatefulSet and pod's ordinal as extracted from its Name. If
// the Pod was not created by a StatefulSet, its parent is considered to be empty string, and its ordinal is considered
// to be -1.
func getParentNameAndOrdinal(pod *v1.Pod) (string, int) {
parent := ""
ordinal := -1
subMatches := statefulPodRegex.FindStringSubmatch(pod.Name)
if len(subMatches) < 3 {
return parent, ordinal
}
parent = subMatches[1]
if i, err := strconv.ParseInt(subMatches[2], 10, 32); err == nil {
ordinal = int(i)
}
return parent, ordinal
}
