我有 statefulset pod。当我进入其中一个 pod 并尝试 ping 它的主机名时。有用。但是，如果我尝试从当前容器 p​​ing 其他 pod 的主机名，那么这些主机名不会得到解析。我也有无头服务。有人可以告诉我在集群级别或在服务或 statefulset 的 yaml 中需要做什么以使通信发生。一个工作示例或一些工作图表链接来尝试，会很有帮助。我可以通过那个。

服务：

apiVersion: v1
kind: Service
metadata:
  name: "{{ .Chart.Name }}-{{ .Chart.AppVersion | replace "." "" }}"
  labels:
    app: "{{ .Chart.Name }}-{{ .Chart.AppVersion | replace "." "" }}"
{{ include "metadata.labels.standard" . | indent 4 }}    
spec:
  clusterIP: None
  selector:
   tier: backend

有状态集：

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: "{{ .Chart.Name }}-{{ .Chart.AppVersion | replace "." "" }}-myapp1"
  labels:
    app: "{{ .Chart.Name }}-{{ .Chart.AppVersion | replace "." "" }}-myapp1"
    tier: backend
spec:
  replicas: 2
  selector:
    matchLabels:
      app: "{{ .Chart.Name }}-{{ .Chart.AppVersion | replace "." "" }}-myapp1"
  serviceName: "{{ .Chart.Name }}-{{ .Chart.AppVersion | replace "." "" }}"
  template:
    metadata:
      labels:
        app: "{{ .Chart.Name }}-{{ .Chart.AppVersion | replace "." "" }}-myapp1"
        tier: backend
      volumes:
        - name: configmap-r
          configMap:
           name: "{{ .Chart.Name }}-{{ .Chart.AppVersion | replace "." "" }}-configmap"
      imagePullSecrets:
        - name: {{ .Values.image.pullSecret }}
      containers:
        - name: "{{ .Chart.Name }}-{{ .Chart.AppVersion | replace "." "" }}-myapp1"
          image: "{{ .Values.image.repository }}:{{ .Values.image.tag }}"
          imagePullPolicy: Always
          ports:
            - containerPort: 8080
          volumeMounts:
            - name: configmap-r
              mountPath: /home/xyz/

要在集群中公开服务，请使用类型值作为 clusterIP。而不是使用规范：clusterIP：无

使用这个：类型：ClusterIP
