OpenStack Tacker介绍 - 3.openstack tacker的简单使用
说明： 本文主要是描述 openstack Pika版本的tacker的简单使用说明（更多请见后面分析）。
tacker是一个NVF管理器，用于管理NVF的生命周期。 Tacker的重点是配置VNF, 并监视他们。
并且支持重启和/或扩展（自动修复）NVF。
本文主要是基于tacker创建一个简单的NVF实例。
1、环境准备
1）3个网络：
net_mgmt：管理网络，需要与云平台管理网络能够通信（flat网络）
(flat网络的环境配置见：
http://blog.csdn.net/linshenyuan1213/article/details/78124661)
net0，net1 两个vxlan网络
2) 镜像获取 cirros-0.3.5-x86_64-disk.img 下载路径
http://download.cirros-cloud.net/0.3.5/
3）一个vnfd的定义文件 tosca-vnfd-nova-flavor.yaml，获取路径：
https://github.com/openstack/tacker/blob/master/samples/tosca-templates/vnfd/tosca-vnfd-nova-flavor.yaml
4) 创建目录，并设置权限
mkdir -p /etc/tacker/vim/fernet_keys
chown tacker:tacker /etc/tacker/* -R
(依次创建VIM，VNFD，VNF)
2、创建一个VIM
1) 定义一个VIM配置文件
# cat /root/config.yaml
auth_url: http://127.0.0.1:5000/v3
username: admin
password: admin
project_name: admin
user_domain_name: Default
project_domain_name: Defaulttacker vim-register --is-default --config-file /root/config.yaml test_vim
3）创建VIM 会使用到mistral，该组件的安装见：

3、创建一个vnfd
# tacker vnfd-create --vnfd-file vnfd/tosca-vnfd-nova-flavor.yaml tosca-vnfd-nova-flavor
Created a new vnfd:

# tacker vnf-create --vnfd-id ef6ef5f4-45c0-4c9c-b360-81069d38da65 test-001
Created a new vnf:
