In Tacker, I have created a VNFD with with autoscaling, template as in [1].

After that while deploying VNF with that VNFD, it failed with error:

vagrant@control:/opt/stack/tacker/samples/tosca-templates/vnfd$ tacker vnf-create --vnfd-id 221dc02a-1a87-4b8e-b782-c8fd8f3c3976 test

As per my observation, root cause is [2] opening file in root dir (i.e. '/'), due to which it giving permission denied.

    Permission issue with heat.

    While deploying a vnf with autoscaling, heat translator failed with
    premission denied error. This issue occured because [1] opening file
    in root dir (i.e. '/'), due to which it giving permission denied.
    Fixing it by setting current working dir as '/temp'

I've exactly same issue on kolla-ansible environment.

Any VNFDs can be used to create VNFs but if trying with VNFD including scaling-policies this issue happen.

Any idea?
