在kubernetes状态中设置pod的自定义原始编号设置非默认值0

Question

在Kubernetes statefulset中，序数以0 --> N开头。是否可以将起始序数设置为自定义数字。

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

Answer 1

不是的。它不支持box.you之外的可能必须自定义状态集控制器。

Answer 2

我想这是你可能会感兴趣的部分：

https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/statefulset/stateful_set_utils.go

// 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
}
