Service Function Chain (SFC) Management
|
|
=======================================
|
|
|
|
Prerequisites
|
|
-------------
|
|
|
|
The following packages should be installed:
|
|
|
|
* tacker
|
|
* python-tackerclient
|
|
|
|
A default VIM should be registered according to :doc:`./cli-legacy-vim`.
|
|
|
|
The following VNFDs are created with the name ``VNFD1`` and ``VNFD2``
|
|
according to :doc:`./cli-legacy-vnfd`.
|
|
|
|
* `tosca-vnffg-vnfd1.yaml <https://opendev.org/openstack/tacker/src/branch/master/samples/tosca-templates/vnffgd/tosca-vnffg-vnfd1.yaml>`_
|
|
* `tosca-vnffg-vnfd2.yaml <https://opendev.org/openstack/tacker/src/branch/master/samples/tosca-templates/vnffgd/tosca-vnffg-vnfd2.yaml>`_
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack vnf descriptor create --vnfd-file tosca-vnffg-vnfd1.yaml VNFD1
|
|
$ openstack vnf descriptor create --vnfd-file tosca-vnffg-vnfd2.yaml VNFD2
|
|
|
|
|
|
The VNFs from the created VNFDs are deployed with the name ``VNF1`` and
|
|
``VNF2`` according to :doc:`./cli-legacy-vnf`.
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack vnf create --vnfd-name VNFD1 VNF1
|
|
$ openstack vnf create --vnfd-name VNFD2 VNF2
|
|
|
|
|
|
A VNFFG should be deployed according to :doc:`./cli-legacy-vnffg`. Before
|
|
deploying the VNFFG, a VNFFGD may need to be created according to
|
|
:doc:`./cli-legacy-vnffgd`.
