我在k8s上部署consul集群，StatefulSet有三个replias。三个pod状态正常，但就是加入不了consul集群，consul集群总是只有一个成员。手动join提示connect refused。

我的服务配置：

apiVersion: apps/v1
kind: StatefulSet
metadata:
name: consul
spec:
selector:
matchLabels:
app: consul
serviceName: consul
replicas: 3
template:
metadata:
labels:
app: consul
spec:
terminationGracePeriodSeconds: 10
containers:
- name: consul
image: consul:latest
args:
- "agent"
- "-server"
- "-bootstrap-expect=3"
- "-ui"
- "-data-dir=/consul/data"
- "-bind=0.0.0.0"
- "-client=0.0.0.0"
- "-advertise=$(PODIP)"
- "-retry-join=consul-0.consul.$(NAMESPACE).svc.cluster.local"
- "-retry-join=consul-1.consul.$(NAMESPACE).svc.cluster.local"
- "-retry-join=consul-2.consul.$(NAMESPACE).svc.cluster.local"
- "-domain=cluster.local"
- "-disable-host-node-id"
volumeMounts:
- name: data
mountPath: /consul/data
env:
- name: PODIP
valueFrom:
fieldRef:
fieldPath: status.podIP
- name: NAMESPACE
valueFrom:
fieldRef:
fieldPath: metadata.namespace
ports:
- containerPort: 8500
name: ui-port
- containerPort: 8400
name: alt-port
- containerPort: 53
name: udp-port
- containerPort: 8443
