ETSI SOL001 Scaling operation support? (openstack vnflcm scale)

Asked by Hariom Sharma on 2020-12-16

I am using the example VNF package from the tacker samples.

https://github.com/openstack/tacker/tree/master/samples/vnf_packages

VNF instantiation is successful. As a next step, I am trying the VNF scaling, but nothing happens when I execute this command. There is no error returned and no logs printed in the logs.

openstack vnflcm scale --type SCALE_OUT --aspect-id worker_instance --number-of-steps 1 47236dd4-2a3a-45a0-bfdf-2f21ea1c8bde

Please let me know if the scale operation is supported or under the works. My tacker version shows 1.4.0

[root@localhost Definitions(keystone_admin)]# tacker --version
1.4.0
[root@localhost Definitions(keystone_admin)]#

Sorry for my late reply. Thank you for your feedback.

We had a bug [1] in scale operation but now it’s fixed with the patch [2]. Could you try it again with the master repository? Also, let me note that the sale operation is now only supported with UserData VNF Package [3]. The new use case document for scale will be available soon [4].
