OpenStack Tacker介绍 - 6.创建一个多网卡的SFC服务链

1、说明

    本文介绍用tacker创建一个多网卡的sfc服务链。

   创建以下sfc配置的tacker模板。

         +----------------+   +----------------+   +----------------+
         |   vnf1_001     |   |   vnf2_001     |   |   vnf3_001     |
         +----------------+   +----------------+   +----------------+
         CP11  CP12|  CP13|   CP21  CP22|  CP23|   CP31  CP32|  CP33|
                   |      |             |      |             |      |
VM CP0->-----------+      +-------------+      +-------------+      +--->

    (虚拟机内部流量需要自己打通：
    可参考：http://blog.csdn.net/linshenyuan1213/article/details/78195061)

2、环境准备

1)网络(根据实际情况创建)
# openstack network create net_mgmt
# openstack network create sfc-net-1
# openstack network create sfc-net-2
# openstack network create sfc-net-3
# openstack network create sfc-net-4
# openstack subnet create --network net_mgmt --subnet-range 192.168.6.0/24 subnet_mgmt
# openstack subnet create --network sfc-net-1 --subnet-range 1.0.0.0/24 sfc-subnet-1
# openstack subnet create --network sfc-net-2 --subnet-range 2.0.0.0/24 sfc-subnet-2
# openstack subnet create --network sfc-net-3 --subnet-range 3.0.0.0/24 sfc-subnet-3
# openstack subnet create --network sfc-net-4 --subnet-range 4.0.0.0/24 sfc-subnet-4
2)镜像
创建一个名为 centos7的镜像(或根据自己情况替换自己已有的镜像名称)
3)云主机规格
创建一个名为 lyh-centos7的规格(或根据自己情况替换自己已有的规格名称)
4)创建一个VM，使用sfc-net-1的网络
   该VM 的CP0 port_id为 79a4e10c-5133-4681-b6a5-e1993884d1ab

3、创建3个VNFD

   这3个配置文件会在文末给出

# tacker vnfd-create --vnfd-file /home/vnffgd_sfc_lyh/sfc-vnffg-vnfd1.yaml vnfd1 
# tacker vnfd-create --vnfd-file /home/vnffgd_sfc_lyh/sfc-vnffg-vnfd2.yaml vnfd2 
# tacker vnfd-create --vnfd-file /home/vnffgd_sfc_lyh/sfc-vnffg-vnfd3.yaml vnfd3

4、创建3个VNF

# tacker vnf-create --vnfd-name vnfd1 vnf1_001
# tacker vnf-create --vnfd-name vnfd2 vnf2_001
# tacker vnf-create --vnfd-name vnfd3 vnf3_001

5、创建1个VNFFGD

# 不带参数格式
# tacker vnffgd-create --vnffgd-file /home/vnffgd_sfc_lyh/sfc-vnffgd-sample.yaml sfcd_001

# 带参数格式
# tacker vnffgd-create --vnffgd-file /home/vnffgd_sfc_lyh/sfc-vnffgd-param.yaml sfcd_002

6、创建1个VNFFG

# 不带参数格式
# tacker vnffg-create --vnffgd-name sfcd_001 
   --vnf-mapping VNFD1:vnf1_001,VNFD2:vnf2_001,VNFD3:vnf3_001 sfc_001

# 带参数格式
# tacker vnffg-create --vnffgd-name sfcd_002 \
    --param-file /home/vnffgd_sfc_lyh/sfc-vnffg-param-file.yaml \
    --vnf-mapping VNFD1:vnf1_001,VNFD2:vnf2_001,VNFD3:vnf3_001 sfc_002

# 参数内容
# cat /home/vnffgd_sfc_lyh/sfc-vnffg-param-file.yaml 
id: 52
net_src_port_id: 79a4e10c-5133-4681-b6a5-e1993884d1ab
ip_dst_pre:
    - 4.0.0.0/24   #这个为vnfd3_01的CP33的网络子网地址

7、创建后的环境sfc配置信息

     通过以下命令，可以看到，sfc的配置与我们手动尝试创建的效果是一致的

# neutron port-pair-list 
# neutron port-pair-group-list 
# neutron flow-classifier-list 
# neutron port-chain-list

8、模板内容

# cat /home/vnffgd_sfc_lyh/sfc-vnffg-vnfd1.yaml
tosca_definitions_version: tosca_simple_profile_for_nfv_1_0_0
