AWS Amazon EC2 Tag

This page shows how to write Terraform for Amazon EC2 Tag and write them securely.

aws_ec2_tag (Terraform)

The Tag in Amazon EC2 can be configured in Terraform with the resource name aws_ec2_tag. The following sections describe 2 examples of how to use the resource and its parameters.

Example Usage from GitHub
resource "aws_ec2_tag" "mytagS0" {
  resource_id = module.vpc.public_subnets[0]
  key         = "Name"
  value       = "instances_samples"
resource "aws_ec2_tag" "mytagS1" {
resource "aws_ec2_tag" "vpc_tag" {
  resource_id = var.vpc_id
  key         = var.cluster_name
  value       = "shared"

Review your Terraform file for AWS best practices

Shisho Cloud, our free checker to make sure your Terraform configuration follows best practices, is available (beta).


Explanation in Terraform Registry

Manages an individual EC2 resource tag. This resource should only be used in cases where EC2 resources are created outside Terraform (e.g., AMIs), being shared via Resource Access Manager (RAM), or implicitly created by other means (e.g., Transit Gateway VPN Attachments).

NOTE: This tagging resource should not be combined with the Terraform resource for managing the parent resource. For example, using aws_vpc and aws_ec2_tag to manage tags of the same VPC will cause a perpetual difference where the aws_vpc resource will try to remove the tag being added by the aws_ec2_tag resource. NOTE: This tagging resource does not use the provider ignore_tags configuration.

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.



Ensure to avoid using default VPC

It is better to define the own VPC and use it.



Ensure your network ACL rule blocks unwanted inbound traffic

It is better to block unwanted inbound traffic.



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).



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.



Ensure your security group blocks unwanted inbound traffic

It is better to block unwanted inbound traffic.

Review your AWS Amazon EC2 settings

In addition to the above, there are other security points you should be aware of making sure that your .tf files are protected in Shisho Cloud.
