Getting Started with ETSI NFV-SOL Tacker¶
Summary¶
This lecture enables you to:
create & delete a sample VNF on the OpenStack with Tacker
Following two types of VNF deployment supported by Tacker are introduced in this lecture.
“VNF Deployment with LCM Operation User Data” is optional. The part will be clarified with the notation [This is UserData specific part].
The following figure shows a sample VNF used in this lecture.
Note
VIM config, a VNF package, and instantiation parameters used in this tutorial are placed at the repository.
Note
You can see logs of Tacker with this command:
$ sudo journalctl -u devstack@tacker.service
$ sudo journalctl -u devstack@tacker-conductor.service
Prerequisites¶
The following packages should be installed [5]:
tacker
python-tackerclient
Configuration¶
Load credentials for client operations¶
Before any Tacker commands can be run, your credentials need to be sourced [6].
You can confirm that Tacker is available by checking this command works without error:
$ openstack vim list
Note
See CLI reference [7] to find all the available commands.
Register VIM¶
Prepare VIM configuration file:
You can use a setup script for generating VIM configuration or edit it from scratch as described in here. This script finds parameters for the configuration, such as user name or password, from your environment variables. Here is an example of generating OpenStack VIM configuration as
vim_config.yaml. In this document,TACKER_ROOTis the root of tacker’s repository on your server.$ bash TACKER_ROOT/tools/gen_vim_config.sh Config for OpenStack VIM 'vim_config.yaml' generated.
There are several options for configuring parameters from command line supported. Refer help with
-hfor details.You can also use a sample configuration file vim_config.yaml instead of using the script.
$ cp TACKER_ROOT/samples/etsi_getting_started/tosca/vim/vim_config.yaml ./ $ vi vim_config.yaml
auth_url: 'http://127.0.0.1/identity' username: 'admin' password: 'devstack' project_name: 'admin' project_domain_name: 'Default' user_domain_name: 'Default' cert_verify: 'True'
Register Default VIM:
Once you setup VIM configuration file, you register default VIM via
openstackcommand with--is-defaultoption.$ openstack vim register --config-file ./vim_config.yaml \ --is-default --fit-width openstack-admin-vim +----------------+-------------------------------------------------+ | Field | Value | +----------------+-------------------------------------------------+ | auth_cred | { | | | "username": "admin", | | | "user_domain_name": "Default", | | | "cert_verify": "True", | | | "project_id": null, | | | "project_name": "admin", | | | "project_domain_name": "Default", | | | "auth_url": "http://127.0.0.1/identity/v3", | | | "key_type": "barbican_key", | | | "secret_uuid": "***", | | | "password": "***" | | | } | | auth_url | http://127.0.0.1/identity/v3 | | created_at | 2020-05-24 07:00:25.923831 | | description | | | id | 4bb57004-9e33-4c52-b5f9-629f876b4168 | | is_default | True | | name | openstack-admin-vim | | placement_attr | { | | | "regions": [ | | | "RegionOne" | | | ] | | | } | | project_id | d413421abf074c9b8f54a1403857038c | | status | PENDING | | type | openstack | | updated_at | None | | vim_project | { | | | "name": "admin", | | | "project_domain_name": "Default" | | | } | +----------------+-------------------------------------------------+

Create and Upload VNF Package¶
Prepare VNF Package¶
Create VNF Package CSAR directories:
$ mkdir -p ./sample_vnf_package_csar/TOSCA-Metadata \ ./sample_vnf_package_csar/Definitions \ ./sample_vnf_package_csar/Files
[This is UserData specific part] When using UserData, create the following directories in addition.
$ mkdir -p ./sample_vnf_package_csar/BaseHOT/simple \ ./sample_vnf_package_csar/UserData
Create a
TOSCA.metafile:$ vi ./sample_vnf_package_csar/TOSCA-Metadata/TOSCA.meta
TOSCA-Meta-File-Version: 1.0 Created-by: Dummy User CSAR-Version: 1.1 Entry-Definitions: Definitions/sample_vnfd_top.yaml
Download ETSI definition files:
You should set
${TOSCA_VERSION}to one of the appropriate TOSCA service template versions [8], e.g.,export TOSCA_VERSION=v2.6.1.Important
You should also check if the version of TOSCA service template is supported by tacker [9].
$ cd ./sample_vnf_package_csar/Definitions $ wget https://forge.etsi.org/rep/nfv/SOL001/raw/${TOSCA_VERSION}/etsi_nfv_sol001_common_types.yaml $ wget https://forge.etsi.org/rep/nfv/SOL001/raw/${TOSCA_VERSION}/etsi_nfv_sol001_vnfd_types.yaml
Create VNFD files:

The

Create VNF Package¶
Execute vnfpkgm create:
Take a note of “VNF Package ID” as it will be used in the next step.
$ cd -

Instantiate VNF¶
Create
<param-file>:Required parameter:
flavourID
Optional parametes:
instantiationLevelId
extVirtualLinks
extManagedVirtualLinks
vimConnectionInfo
Note
You can skip
vimConnectionInfoonly when you have the default VIM.A sample
<param-file>named assample_param_file.jsonwith minimal parametes:$ vi ./sample_param_file.json
When using TOSCA, use the following parameters.
{ "flavourId": "simple" }
[This is UserData specific part] When using UserData, use the following parameters instead.
{ "flavourId": "simple", "extVirtualLinks": [ { "id": "net0", "resourceId": "${network_uuid}", "extCps": [ { "cpdId": "CP1", "cpConfig": [ { "cpProtocolData": [ { "layerProtocol": "IP_OVER_ETHERNET", "ipOverEthernet": { "ipAddresses": [ { "type": "IPV4", "numDynamicAddresses": 1, "subnetId": "${subnet_uuid}" } ] } } ] } ] } ] } ], "vimConnectionInfo": [ { "id": "e24f9796-a8e9-4cb0-85ce-5920dcddafa1", "vimId": "${vim_uuid}", "vimType": "ETSINFV.OPENSTACK_KEYSTONE.v_2" } ], "additionalParams": { "lcm-operation-user-data": "./UserData/lcm_user_data.py", "lcm-operation-user-data-class": "SampleUserData" } }
${network_uuid},${subnet_uuid}and${vim_uuid}should be replaced with the uuid of the network to use, the uuid of the subnet to use and the uuid of the VIM to use, respectively.Hint
You can find uuids of the network and the corresponding subnet with this command [10]:
$ openstack network list
Instantiate VNF:
The “ID of vnf instance” and “path to <param-file>” are needed to instantiate vnf.
