Validation error with example project #99

Closed stefanbschneider closed 5 years ago

stefanbschneider commented 5 years ago

I'm getting an validation error that I don't understand when running 

tng-validation --project example-project

on the example project defined in the tng-sdk-project repo: https://github.com/sonata-nfv/tng-sdk-project/tree/master/example-project

The error is

2019-08-16 14:44:39 nb-stschn tango.validator.events:l50 ERROR Undefined connection point
2019-08-16 14:44:39 nb-stschn tango.validator.events:l64 ERROR Function descriptor (VNFD) of vnf_id='vnf1' declared in connection point 'vnf1' in virtual link 'input' is not defined

I don't get what the error message is referring to. there is no connection point vnf1 referenced in the vnfd: https://github.com/sonata-nfv/tng-sdk-project/blob/master/example-project/tango_vnfd0.yml I also don't see any other issue with the descriptor

Not sure, who's currently working on the validator and could help me out with this? @MiguelRivasQuobis @anapolg

Hi @stefanbschneider one question:

How do you define virtual links between vnf1 and vnf2 in tango_nsd when you only have one function defined in the service which is vnf0? Am I missing something in there?

Also in tango_vnfd0, you have several CPs which I am not sure they have the right type. For example, the mgmt one in the defined CDU has type internal. I would say it should be management. Anyway, I do not think that will give you an error if you consider all the connected CPs as the same type. You should review that part cause I find it messy changing the type between each end of the virtual link.. not sure if that is correct.

You're right, the thing with the VNFs in the NSD is weird - I'll have a look! Thanks for the hint
