Example Usage from GitHub

ec2_fleet-main.tf#L1
resource "aws_ec2_fleet" "main" {
  type                               = var.ec2_fleet_type
  tags                               = merge({ Name = var.ec2_fleet_name }, var.tags, var.ec2_fleet_tags)
  terminate_instances                = var.ec2_terminate_instances

    launch_template_specification {
    #   launch_template_id = "lt-0bd6ecc75445e53cb"
      launch_template_id = aws_launch_template.launch-template.id
      # launch_template_id = data.aws_launch_template.default.id

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.

risk-label

aws_default_vpc

Ensure to avoid using default VPC

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

risk-label

aws_network_acl_rule

Ensure your network ACL rule blocks unwanted inbound traffic

It is better to block unwanted inbound traffic.

risk-label

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).

risk-label

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.

risk-label

aws_security_group

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.

Parameters

>> from AWS CloudFormation Documentation

Explanation in CloudFormation Registry

Specifies the configuration information to launch a fleet--or group--of instances. An EC2 Fleet can launch multiple instance types across multiple Availability Zones, using the On-Demand Instance, Reserved Instance, and Spot Instance purchasing models together. Using EC2 Fleet, you can define separate On-Demand and Spot capacity targets, specify the instance types that work best for your applications, and specify how Amazon EC2 should distribute your fleet capacity within each purchasing model. For more information, see Launching an EC2 Fleet in the Amazon EC2 User Guide for Linux Instances.
