Terrform launch aws_instance with existing security group

 Terraform launch aws_instance with existing security group

Hi Friends 😀, 

Before going ahead,😌  I am assuming that we all have bit knowledge of how terraform works for AWS infrastructure.

You can learn more on it official site  Terraform By HashiCorp .💥💥

We can create new security group and attached to newly created AWS instance with terraform.

But some time we require to attached existing Security Group only. 💁

Here , I am helping out in such condition. 😎

👉First, Create main.tf terraform file. 

👉Then use vpc_security_group_ids field as mentioned below 

provider "aws" {

    region = "ap-south-1"

}

resource "aws_instance" "Instance_from_ami" {

    ami = "your_ami_ID"

    instance_type = "t2.micro"

    vpc_security_group_ids = [ 

                "your_sg_group1",

                "your_sg_group2" 

]

    tags = {

Created_Instance_from = "Terraform_script"

    }

}

👉Then use terraform command to apply your template.

👉If  you are using .tfvars file then below are one method you can use.

✔your variables.tf ,

variable "sg_ID" { 

}

 

✔your .tfvars file ,

sg_ID="my_security_group"

✔your main.tf file,

provider "aws" {

    region = "ap-south-1"

}

resource "aws_instance" "Instance_from_ami" {

    ami = "your_ami_ID"

    instance_type = "t2.micro"

    vpc_security_group_ids = [ var.sg_ID ]

    tags = {

Created_Instance_from = "Terraform_script"

    }

}

👉Then apply your terraform command with -var-file attribute .
