create a Web site-to-Web site VPN in Terraform

To create a site-to-site VPN utilizing Terraform, you should use the aws_vpn_gateway and aws_vpn_connection assets 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 = {
    Identify = "SiteToSiteVPN"
  }
}

useful resource "aws_vpn_connection" "vpn_connection" {
  customer_gateway_id = "<CUSTOMER_GATEWAY_ID>"
  vpn_gateway_id     = aws_vpn_gateway.vpn_gateway.id
  kind               = "ipsec.1"
  static_routes_only = true

  tags = {
    Identify = "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 could change <VPC_ID> with the ID of the VPC the place the VPN gateway can be connected, <CUSTOMER_GATEWAY_ID> with the ID of the shopper gateway representing the distant website, and <DESTINATION_CIDR_BLOCK> with the CIDR block of the distant community you wish 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 desired VPC, and the VPN connection is related to the shopper gateway and the VPN gateway. The VPN connection route specifies the vacation spot CIDR block that must be routed via the VPN connection.

After you have the Terraform configuration prepared, you possibly can initialize the Terraform mission, plan the infrastructure adjustments, and apply them utilizing the Terraform CLI. The VPN assets can be provisioned based mostly on the configuration offered.
