os-service-type does not work for tackerclient

[wangchenglong]

Hi,
My tacker version is stable/Ocata. I install tacker in controller node and network node.
And the controller node's host name is 'tacker-nfvm', the network node's host name is 'tacker-server'.
both nodes' tackers can be running ok.

In order to test the tacker client's --os-service-type, I create I create two service-type for tacker.

root@controller:/home/user# openstack service list|grep tacker
| 29b7eacb4c3341bfbc2acf0fc4804820 | tacker | nfv-management |
| a974817ceeb3431492c55a0f7693771e | tacker | nfv-orchestration |

and I also provide an endpoint for tacker-server with different service-type, nfv-management and nfv-orchestration.

| 2347ad5a0db049deaebed501df0d458f | RegionOne | tacker | nfv-management | True | admin | http://tacker-vnfm:9890/ |
| 42341f79d0d04fb5a1122165d1bfd70b | RegionOne | tacker | nfv-orchestration | True | internal | http://tacker-server:9890/ |
| 7b9cb1daffcb4bbb9af240657d16385d | RegionOne | tacker | nfv-orchestration | True | admin | http://tacker-server:9890/ |
| 86a1a30b561d4b25ae226f5718ef17db | RegionOne | tacker | nfv-management | True | internal | http://tacker-vnfm:9890/ |
| b4b54626de1c4d939d3ec30f6f9515b0 | RegionOne | tacker | nfv-management | True | public | http://tacker-vnfm:9890/ |
| d01e8082308d443bb760958ab4ef0c69 | RegionOne | tacker | nfv-orchestration | True | public | http://tacker-server:9890/ |

In controller, I request vnfd list using --os-service-type.

 command is "tacker --os-service-type nfv-management vnfd-list --debug".

but it's strange that the endpoint's url is not tacker-vnfm:9890 but tacker-server:9890.

the debug is follwing:

tacker --os-service-type nfv-management vnfd-list --debug

when I stop the network node's tacker, the result is :

Unable to establish connection to http://tacker-server:9890/v1/vnfds.json?template_source=onboarded

why client's --os-service-type does not work ?

[yong sheng gong (gongysh)]

think it is not easy for user to be used to new service_type, so for the time being, just make it fix-coded.
