Just this week I published a Terraform module for setting up an OCI-Azure interconnect. This basically is the code I already provided earlier and described in a few of my older posts.
What you will get
The module will create a few resources on Azure and OCI to set up the interconnect. These resources are highlighted in blue in the following diagram.
In detail, the module will create
- in OCI
- DRG
- FastConnect Virtual Circuit
- Interconnect Route Table
- Service Gateway (optional)
- Service Gateway Route Table (optional)
- in Azure
- Gateway Subnet
- Express Route Circuit
- Virtual Network Gateway (including a public ip)
What you need to create yourself
Before you can use the module, you need to create a few resources yourself. You need to provide these in the module configuration.
- OCI Compartment
- OCI VCN
- Azure Resource Group
- Azure VNET
How to use in your own environment
The following sample shows the module configuration. The parameters are described at https://github.com/maxjahn/terraform-oci-azure-interconnect
module "interconnect" {
source = "maxjahn/azure-interconnect/oci"
version = "1.0.0"
oci_compartment_ocid = var.oci_compartment_ocid
oci_vcn_id = oci_core_virtual_network.service_vcn.id
az_resource_group_name = "interconnect_ams"
az_vnet_name = "interconnect_vnet"
az_gw_subnet_cidr = "10.1.99.0/24"
az_expressroute_peering_location = "Amsterdam2"
interconnect_peering_net = "10.99.0.0/24"
# optional
enable_service_transit_routing = 0
az_expressroute_sku = "Standard"
az_expressroute_bandwidth = 1000
oci_fastconnect_bandwidth = "1 Gbps"
}
