What happened:
Using this article, I am assigning IPs to my docker containers from azure-vnet. Earlier I was having a single network interface for my azure VM, so after adding IP configuration to that Interface I was getting those IPs for my docker containers, Now I added another network interface to my existing VM and now when I go to create a network of type 'azure-vnet', I get an error saying 'Invalid CIDR Address' and sometimes I get 'Subnet not found', What could be the reason for it?

What you expected to happen:
I should be able to create 'azure-vnet' type network for the subnet used in my secondary Network interface.

How to reproduce it (as minimally and precisely as possible):
Create an azure vm with a single NIC, using the CNM plugin create a 'azure-vnet' type network and assign IPs to your docker container from that subnet, now add another NIC to your vm and then try to do the same step and you will face error while creating the 'azure-vnet' network

right now we don't support this scenario

Thanks for the answer, however you should update the release docs where it is mentioned that you can join a container to multiple virtual networks
V1.0.8

@guddutopper that support is only for internal customers. sorry for the confusion.
