. The following sections describe 5 examples of how to use the resource and its parameters.
Example Usage from GitHub
resource "aws_ec2_transit_gateway_vpc_attachment_accepter" "vpc1" {
provider = aws.apptest0
transit_gateway_attachment_id = module.vpc1.tgw_attachment_id.0
}
#resource "aws_ram_resource_share_accepter" "accept_apptest1" {
resource "aws_ec2_transit_gateway_vpc_attachment_accepter" "accept_tgw_attachment_in_intersite" {
provider = aws.intersite
transit_gateway_attachment_id = aws_ec2_transit_gateway_vpc_attachment.transit_gateway_attachment.id
tags = {
Name = var.name
resource "aws_ec2_transit_gateway_vpc_attachment_accepter" "this" {
count = local.enabled ? 1 : 0
tags = merge(var.tags, map("Name", var.name))

Explanation in Terraform Registry
Manages the accepter's side of an EC2 Transit Gateway VPC Attachment. When a cross-account (requester's AWS account differs from the accepter's AWS account) EC2 Transit Gateway VPC Attachment is created, an EC2 Transit Gateway VPC Attachment resource is automatically created in the accepter's account. The requester can use the
aws_ec2_transit_gateway_vpc_attachment
resource to manage its side of the connection and the accepter can use theaws_ec2_transit_gateway_vpc_attachment_accepter
resource to "adopt" its side of the connection into management.
Tips: Best Practices for The Other AWS Amazon EC2 Resources
In addition to the aws_default_vpc, AWS Amazon EC2 has the other resources that should be configured for security reasons. Please check some examples of those resources and precautions.
aws_default_vpc
Ensure to avoid using default VPC
It is better to define the own VPC and use it.
aws_network_acl_rule
Ensure your network ACL rule blocks unwanted inbound traffic
It is better to block unwanted inbound traffic.
aws_ebs_volume
Ensure to use a customer-managed key for EBS volume encryption
It is better to use a customer-managed key for EBS volume encryption. It can be gain more control over the encryption by using customer-managed keys (CMK).
aws_instance
Ensure to avoid storing AWS access keys in user data
It is better to avoid storing AWS access keys in user data. `aws_iam_instance_profile` could be used instead.
aws_security_group
Ensure your security group blocks unwanted inbound traffic
It is better to block unwanted inbound traffic.
