Variables.tf file
The provider and the resource blocks in the main.tf file can be configured by changing the values in variables.tf file.
For example, if you want to change the aws_instace type from t2.small to t2.micro, replace the value here in this block.
variable "aws_instance" {
type = string
description = "instance_type"
default = "t2.small"
}
Other resource-specific values like aws_region, aws_ami, vpc and the subnet can also be changed the same way by editing the variable.tf file.
