terraform-aws-ec2

Terraform AWS EC2 Module

-->

Terraform module to provision AWS [EC2]

Introduction

The module will create:

• EC2 Instance

Usage

1. Create main.tf config file, copy/paste and customize the following configuration.

Operating system selection

Operating system
al2023
amazon2
centos7
centos8
rhel6
rhel7
rhel8
rhel9
ubuntu1804
ubuntu1810
ubuntu1904
windows2019
windows2019SQL2016E
windows2016
windows2012r2
customlinux
customwin

The os variable is used to auto-select an appropriate latest Amazon Machine Image (ami) corresponding to the OS.

For cases requiring a certain ami, provide a specific value for the ami variable. This will preclude any values provided for the os variable, which will be ignored.

Instance type and size selection

Specifying values for vcpu_count and memory_gb will auto-select a preferred instance type and size. If a value for only one of these two variables is provided, the minimum possible value will be used for the other (example: setting memory_gb = 1 without providing a value for vcpu_count will implicitly set vcpu_count to 2, corresponding to 2 vCPU, 1 GB memory micro size).

Note that not all vcpu_count and memory_gb combinations are valid. For example, there is not an instance type with 16 vCPUs and 1 GB memory.

For cases requiring a certain instance type, provide a specific value for the instance_type variable. This will preclude any values provided for vcpu_count or memory_gb, which will be ignored.

# make sure you deploy the security group before creating ec2 instance, ec2 instance depends on the security group.

2. (Optional) create outputs.tf config file, copy/paste the following configuration.

output "instance_name" {
description = "The tag name for this instance"
value = var.tags.Name
}
output "instance_id" {
  description = "Instance ID"
  value       = join("", aws_instance.this.*.id)
}
output "instance_arn" {
  description = "Instance ID"
  value       = join("", aws_instance.this.*.arn)
}
output "instance_public_ip" {
  description = "Instance ip"
  value       = join("", aws_instance.this.*.public_ip)
}
output "instance_private_ip" {
  description = "Instance ip"
  value       = join("", aws_instance.this.*.private_ip)
}
