Hi All,

Please find below the steps to set-up tacker for managing vnf packages.

Steps to set-up tacker for managing vnf packages:-

1. Api-paste.ini

        [composite:tacker]
        /vnfpkgm/v1: vnfpkgmapi_v1

        [composite:vnfpkgmapi_v1]
        use = call:tacker.auth:pipeline_factory
        noauth = request_id catch_errors extensions vnfpkgmapp_v1
        keystone = request_id catch_errors authtoken keystonecontext extensions vnfpkgmapp_v1

        [app:vnfpkgmapp_v1]
        paste.app_factory = tacker.api.vnfpkgm.v1.router:VnfpkgmAPIRouter.factory

You can also copy api-paste.ini available in patch : https://review.opendev.org/#/c/675593

2. Configuration options changes : tacker.conf

a) Periodic task to delete the vnf package artifacts from nodes and glance store.
        default configuration in tacker/tacker/conf/conductor.py

        vnf_package_delete_interval = 1800

b) Path to store extracted CSAR file on compute node
        default configuration in tacker/conf/vnf_package.py

        vnf_package_csar_path = /var/lib/tacker/vnfpackages/

        vnf_package_csar_path should have Read and Write access (+rw)


c) Path to store CSAR file at glance store
        default configuration in /devstack/lib/tacker

        filesystem_store_datadir = /var/lib/tacker/csar_files

        filesystem_store_datadir should have Read and Write access (+rw)

3. Apply python-tackerclient patches
        https://review.opendev.org/#/c/679956/
        https://review.opendev.org/#/c/679957/
        https://review.opendev.org/#/c/679958/

4. Apply tosca parser changes
        https://review.opendev.org/#/c/675561/

5. Sample CSAR file to create VNF package tacker/tacker/samples/vnf_packages/sample_vnf_pkg.zip

6. Commands to manage VNF packages

        To create a VNF package

                - openstack vnfpack create —user-data key=value

                <package_UUID> will be generated by this command which will be used in other commands to manage VNF Package.

        To upload the CSAR file

                1. using direct path

                        - openstack vnfpack upload <package_UUID>  --upload-method direct-file --path <path of CSAR file>

                2. using web

                        - openstack vnfpack upload <package_UUID> --upload-method web-download  --path <web URL>

        To list all the VNF Package

                        - openstack vnfpack list

        To show a VNF package details

                        - openstack vnfpack show <package_UUID>

        To delete a VNF package

                        - openstack vnfpack delete <package_UUID>

        use `openstack vnfpack --help` command for more information
