Getting Started¶
Once Tacker is installed successfully, follow the steps given below to get started with Tacker and validate the installation.
Registering default OpenStack VIM¶
- Get one account on the OpenStack VIM.
 
In Tacker MANO system, the VNF can be on-boarded to one target OpenStack, which is also called VIM. Get one account on this OpenStack. For example, the below is the account information collected in file vim_config.yaml [1]:
auth_url: 'http://127.0.0.1/identity'
username: 'nfv_user'
password: 'mySecretPW'
project_name: 'nfv'
project_domain_name: 'Default'
user_domain_name: 'Default'
cert_verify: 'True'
Note
In Keystone, port 5000 is enabled for authentication service [2], so the end users can use auth_url: ‘http://127.0.0.1:5000/v3’ instead of auth_url: ‘http://127.0.0.1/identity’ as above mention.
By default, cert_verify is set as True. To disable verifying SSL certificate, user can set cert_verify parameter to False.
2. Register the VIM that will be used as a default VIM for VNF deployments. This will be required when the optional argument –vim-id is not provided by the user during VNF creation.
openstack vim register --config-file vim_config.yaml \
       --description 'my first vim' --is-default hellovim
Onboarding sample VNF¶
- Create a sample-vnfd.yaml file with the following template:
 
tosca_definitions_version: tosca_simple_profile_for_nfv_1_0_0
