我正在制作一个自定义 REDIS StatefulSet yaml。到目前为止，我已经成功部署了应用程序，但是 REDIS SLAVE 有问题。它找不到主人，我没有猜测DNS配置错误的原因。

我的 StatefulSet 看起来像这样：

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: redis-server
  namespace: scm
  labels:
    app.k8s/name: redis
    app.k8s/instance: server
spec:
  replicas: 3
  serviceName: redis-server
  
  selector:
    matchLabels:
      app.k8s/name: redis
      app.k8s/instance: server
  
  template:
    metadata:
      labels:
        app.k8s/name: redis
        app.k8s/instance: server
    spec:
      containers:
        - name: redis-server
          image: redis:6.0.9-alpine
          imagePullPolicy: IfNotPresent
          command: ["redis-server", "/data/conf/redis.conf"]
          ports:
            - name: redis
              containerPort: 6379

和一个看起来像这样的无头服务：

apiVersion: v1
kind: Service
metadata:
  name: redis-server-headless
  namespace: scm
  labels:
    app.k8s/name: redis
    app.k8s/instance: server
    app.k8s/part-of: gitlab
spec:
  type: ClusterIP
  clusterIP: None
  publishNotReadyAddresses: true
  ports:
    - name: server
      port: 6379
      protocol: TCP
      targetPort: redis
  selector:
    app.k8s/name: redis
    app.k8s/instance: server

当我这样做时，nslookup redis-server-headless我可以找到 IP 地址，但是当我尝试时，ping redis-server-0.redis-server-headless或者ping redis-server-0.redis-server我收到错误的地址错误消息。

我错过了什么？

你serviceName的 redis statefuleset 应该是redis-server-headless.
