vFirewall IP assignment

huntingweb

Lab 8.0, there are 3 scenarios defined in config.py.
I was able to run scenario 1, creates CNFs in another Kubernetes domain.

I don't understand:
1) Does SDNC assign the IP addresses for vfw_int_private1_ip_0, vpg_int_private1_ip_0?
2) How does SNDC know how to assign the IP address?
3) If it is done through DG script, how does SDNC know which DG script to be invoked?
4) If it is done by CDS, how does SDNC know which CDS to be invoked?

I had been stuck for a few days.
Don't think can figure out by myself.

Please help.

David Xie

Hi @huntingweb,

The IP addresses are defined in the Helm Charts of the CNF.
You can find the values in values.yaml of the CNF Helm charts.
