Guide to setting up vnet to vnet connection in azure with terraform

[jonathan-kosgei]

Is it possible to automate the creation of a vnet to vnet connection between subscriptions on azure with terraform? Has anyone done this before?

Hi @jonathan-kosgei,

Are you referring to Virtual Network Gateways or Virtual Network Peering which just entered public preview recently, or something else?

I've got a mostly-complete PR for Virtual Network Gateways and their Connection resource, I'm waiting for the Azure team to update me on an API issue found while testing.

#8041 is the issue for tracking Virtual Network Peering, you can see there it's currently blocked by the Azure SDK for Go lacking methods to interact with that resource.

Just read a bit on vnet peering, I'm barely into it trying to grasp the different between azure's classical and resource manager models. I'm looking for a way to connect virtual networks between subscriptions and I'm looking to automate it via terraform. It seems rather daunting so I was wondering if anyone else has ever run into this?

Hi @jonathan-kosgei,

Peering can be used to connect networks between subscriptions, however it cannot link Classic VNets to other Classic VNets.
The requirements and limits are described in the documentation.

If you aren't able to use Peering due to it's limits then you may have to use a Virtual Network Gateway to connect the networks.

Neither of these resources are available in Terraform yet however.
