To create a site-to-site VPN utilizing Terraform, you should use the aws_vpn_gateway and aws_vpn_connection sources from the AWS supplier. Right here’s an instance Terraform configuration to create a site-to-site VPN:
useful resource "aws_vpn_gateway" "vpn_gateway" {
vpc_id = "<VPC_ID>"
tags = {
Title = "SiteToSiteVPN"
}
}
useful resource "aws_vpn_connection" "vpn_connection" {
customer_gateway_id = "<CUSTOMER_GATEWAY_ID>"
vpn_gateway_id = aws_vpn_gateway.vpn_gateway.id
sort = "ipsec.1"
static_routes_only = true
tags = {
Title = "SiteToSiteVPNConnection"
}
}
useful resource "aws_vpn_connection_route" "vpn_connection_route" {
destination_cidr_block = "<DESTINATION_CIDR_BLOCK>"
vpn_connection_id = aws_vpn_connection.vpn_connection.id
}
Within the above Terraform configuration, you must change <VPC_ID> with the ID of the VPC the place the VPN gateway shall be connected, <CUSTOMER_GATEWAY_ID> with the ID of the client gateway representing the distant web site, and <DESTINATION_CIDR_BLOCK> with the CIDR block of the distant community you need to hook up with.
This configuration creates a VPN gateway (aws_vpn_gateway), a VPN connection (aws_vpn_connection), and a VPN connection route (aws_vpn_connection_route). The VPN gateway is connected to the required VPC, and the VPN connection is related to the client gateway and the VPN gateway. The VPN connection route specifies the vacation spot CIDR block that ought to be routed by way of the VPN connection.
After you have the Terraform configuration prepared, you may initialize the Terraform undertaking, plan the infrastructure modifications, and apply them utilizing the Terraform CLI. The VPN sources shall be provisioned based mostly on the configuration offered.
