    我找到了使dhcpd pod运行良好的解决方案。
以下示例是服务于k8s服务网络（clusterIPs）之外的外部网络。
dhcp配置如下：
  </p>
   <pre>
    <code>
      include "/etc/dhcp/dhcpd-options.conf";

subnet 192.168.0.0 netmask 255.255.0.0 {}

# management network
subnet 10.0.0.0 netmask 255.255.0.0 {
  option routers 10.0.255.254;
  option broadcast-address 10.0.255.255;
  next-server 10.0.100.6;
  include "/etc/dhcp/lease-bmc.conf";
  include "/etc/dhcp/lease-node.conf";
}

</code>
  </pre>
  <P>
    k8s服务如下：
  </p>
  <P>
    $ cat dhcpd-service.yaml
  </p>
   <pre>
    <code>
      apiVersion: v1
kind: Service
metadata:
  name: dhcpd
  namespace: kube-mngt
spec:
  selector:
    app: dhcpd
  ports:
  - protocol: UDP
    port: 67
    targetPort: 67
  externalIPs:
  - 10.0.100.5

</code>
  </pre>
  <P>
    然后，配置交换机（接口vlan X）以指定指向dhcp服务器的帮助程序地址（在我们的示例中为10.0.100.5）
  </p>
   <pre>
    <code>
      interface Vlan1
 ip address 10.0.255.254 255.255.0.0 secondary
 ip address 10.0.0.1 255.255.0.0
 ip helper-address 10.0.100.5
!

</code>
  </pre>
