Getting Started with Legacy Tacker

Once Tacker is installed successfully, follow the steps given below to get started with Tacker and validate the installation.

Registering Default OpenStack VIM

  1. Get one account on the OpenStack VIM

    In Tacker MANO system, VNFs can be on-boarded to a target OpenStack which is also called as VIM. Get one account on your OpenStack, such as admin if you deploy your OpenStack via devstack. Here is an example of a user named as nfv_user and has a project nfv on OpenStack for VIM configuration. It is described in 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 VIM

    Register the default VIM with the config file for VNF deployment. 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

  1. Create a sample-vnfd.yaml file with the following template

    tosca_definitions_version: tosca_simple_profile_for_nfv_1_0_0

description: Demo example

metadata:
  template_name: sample-tosca-vnfd

topology_template:
  node_templates:
    VDU1:
      type: tosca.nodes.nfv.VDU.Tacker
      capabilities:
        nfv_compute:
          properties:
            num_cpus: 1
            mem_size: 512 MB
            disk_size: 1 GB
      properties:
        image: cirros-0.5.2-x86_64-disk
        availability_zone: nova
        mgmt_driver: noop
        config: |
          param0: key1
          param1: key2

    CP1:
      type: tosca.nodes.nfv.CP.Tacker
      properties:
        management: true
        order: 0
        anti_spoofing_protection: false
      requirements:
        - virtualLink:
            node: VL1
        - virtualBinding:
            node: VDU1

    VL1:
      type: tosca.nodes.nfv.VL
      properties:
        network_name: net_mgmt
        vendor: Tacker

    Note

    You can find several samples of tosca template for VNFD at [3].

  2. Create a sample VNFD

    $ openstack vnf descriptor create --vnfd-file sample-vnfd.yaml samplevnfd

  3. Create a VNF

    $ openstack vnf create --vnfd-name samplevnfd samplevnf

  4. Some basic Tacker commands

    You can find each of VIM, VNFD and VNF created in previous steps by using list subcommand.

    $ openstack vim list
$ openstack vnf descriptor list
$ openstack vnf list

    If you inspect attributes of the instance, use show subcommand with name or ID. For example, you can inspect the VNF named samplevnf as below.

    $ openstack vnf show samplevnf
