S3 bucket Creation

There are two methods to do this:

1. Manually giving buckets names for each buckets
2. Using Increment in Variable to add numbers after specific Unique name

Method 1 : Manually Adding Bucket Names

Filename: Main.tf

resource "aws_s3_bucket" "my-known-buckets" {
  count     = length(var.bucket_names) 
  bucket    = var.bucket_names[count.index]
}

Filename: vars.tf

variable "bucket_names" {
  description = "List of S3 bucket names"
  type        = list(string)
  default     = ["chandratsdfsdasfdfaara", "nayantara123qq3112", "rocketshopzxys", "123asdxzsdgheoi", "asdf21alkj44dsfj"]
}

Filename: provider.tf

terraform {
  required_providers {
    aws = {
      source = "hashicorp/aws"
      version = "5.80.0"
    }
  }
}
 
provider "aws" {
  # Configuration options
  region = "us-east-1"
}

This will create 5 buckets with the given names ["chandratsdfsdasfdfaara", "nayantara123qq3112", "rocketshopzxys", "123asdxzsdgheoi", "asdf21alkj44dsfj"]

Apply it using terraform plan terraform apply

You can list s3 buckets with aws cli commands

aws s3 ls

Method 2: Using Increment in Variable to add numbers after specific Unique name

Use this method when you have too many buckets to create and naming doesnt really matters then this will save your time as you only need to change bucket count in vars.tf file

Filename: main.tf

resource "aws_s3_bucket" "c" {
  count     = var.bucket_count
  bucket    = "wingardiumleviosamybucketsintheair-${count.index + 1}"
}

Filename: vars.tf

variable "bucket_count" {
	description = "number of s3 buckets to create"
	type = number
	default = 5
}
