Kubernetes YAML 文件启动报错：`ipFamilies` 映射问题

根据提供的信息，第九行应该是 'ipFamilies' 的定义。根据 Kubernetes 官方文档，'ipFamilies' 属性应该放在 'spec' 下面，而不是 'ipFamilyPolicy' 的下面。因此，可以尝试将第8行和第9行位置互换，使其符合规范：

spec:
  ipFamilies:
    - IPv4
    - IPv6
  ipFamilyPolicy: RequireDualStack

修改后的 YAML 文件如下：

apiVersion: v1
kind: Service
metadata:
  name: dw-lancelot
  labels:
    app: dw
spec:
  ipFamilyPolicy: RequireDualStack
  ports:
    - port: 8888
      targetPort: 8888
      nodePort: 31111
      protocol: TCP

  type: NodePort
  selector:
    app: dw
    tier: lancelot

            - mountPath: "/var/log/deepwatch"
              name: epic-logs
          ports:
            - containerPort: 8888
              name: http-port
      volumes:
        - name: epic-docs
          hostPath:

        - name: epic-logs
          hostPath:
            path: "/apps/logs"
