Kubernetes StatefulSet 与持久卷管理实战

Headless Service

apiVersion: v1
kind: Service
metadata:
  name: db
  namespace: app
spec:
  clusterIP: None
  selector:
    app: db
  ports:
    - port: 5432
      name: db

StatefulSet 与卷模板

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: db
  namespace: app
spec:
  serviceName: db
  replicas: 3
  selector:
    matchLabels:
      app: db
  template:
    metadata:
      labels:
        app: db
    spec:
      containers:
        - name: db
          image: postgres:15
          ports:
            - containerPort: 5432
          volumeMounts:
            - name: data
              mountPath: /var/lib/postgresql/data
  volumeClaimTemplates:
    - metadata:
        name: data
      spec:
        accessModes: [ "ReadWriteOnce" ]
        resources:
          requests:
            storage: 20Gi

总结

通过 Headless Service 提供稳定 DNS，StatefulSet 保持稳定标识并为每个副本自动创建 PVC，确保有状态服务的可靠运行。
