local value

 


 NOTE:  we can use multiple services from one account. we can use tag for each resource. ==local value is a good concept than tags == if we need to change tag only we need to change local value.

vim aaa.tf

provider "aws" {

  region     = "us-east-1"

  access_key = "AUGQ"

  secret_key = "Kft1aurid"

}



locals {

  common_tag = {

   Name = "uk-project"

   Owner = "moon"

}

}


locals {

 usa = {

 Name = "us-pro"


}



}




resource "aws_instance" "web" {

  ami           = "ami-0ed9277fb7eb570c9"

  instance_type = "t3.micro"

  tags           = local.common_tag


}


resource "aws_vpc" "main" {

  cidr_block       = "10.0.0.0/16"

  instance_tenancy = "default"

  tags           = local.common_tag



}


resource "aws_ebs_volume" "example" {

  availability_zone = "us-east-1a"

  size              = 40

  tags           = local.common_tag



}



resource "aws_instance" "us1" {

  ami           = "ami-0ed9277fb7eb570c9"

  instance_type = "t3.micro"

  tags           = local.usa


}


resource "aws_vpc" "us2" {

  cidr_block       = "10.0.0.0/16"

  instance_tenancy = "default"

  tags           = local.usa



}



resource "aws_ebs_volume" "us3" {

  availability_zone = "us-east-1a"

  size              = 40

  tags           = local.usa



}
