VDU configuration support

Asked by ajinkya

I would like to know if there is any way to do VDU level configuration using tacker? Once a VDU is spawned, is there any way to run user provided script to make it usable? Script that I am referring to over here can considered as scripts for chef/puppet etc.
Only method that I am currently aware of is user data section from VDU configuration where we can do cloud-init scripting.

Are you looking to run the script inside the VDU virtual machine or outside on the tacker controller side ? There is a mgmt-driver framework, where a script can run within the context of Tacker immediately after a VDU is spawned.

Yes, user-data is the way to run scripts within the context of the VDU,

http://docs.openstack.org/developer/tacker/devref/vnfd_template_description.html#providing-user-data

Now, can't you use this user-data to start puppet agent within the VDU ?

Thanks for clarification Sridhar. I am currently using user data only. Just wanted to understand if there is some other way as well.
Could you give me scenario where mgmt driver would come handy ? Is it for VDU specific configuration or entire VNF level configuration ?

Can you help with this problem?
