Lab 36: Security Group Variable Setup Using Terraform

The Nautilus DevOps team is enhancing infrastructure automation and needs to provision a Security Group using Terraform with specific configurations.

For this task, create an AWS Security Group using Terraform with the following requirements:

1. The Security Group name datacenter-sg should be stored in a variable named KKE_sg.

Note:

• 1. The configuration values should be stored in a variables.tf file.
• 1. The Terraform script should be structured with a main.tf file referencing variables.tf.

1. The Terraform working directory is /home/bob/terraform.

2. Right-click under the EXPLORER section in VS Code and select Open in Integrated Terminal to launch the terminal.

# /home/bob/terraform/variables.tf
variable "KKE_sg" {
  description = "The name for the Security Group"
  type        = string
  default     = "datacenter-sg"
}

# /home/bob/terraform/main.tf

# Define the Security Group resource
resource "aws_security_group" "datacenter" {
  name        = var.KKE_sg
  description = "Security Group for datacenter services"

  # Optional: Default ingress/egress rules for illustration, though not explicitly required by the prompt
  ingress {
    description = "Allow all from within the Security Group"
    from_port   = 0
    to_port     = 0
    protocol    = "-1"
    self        = true
  }

  egress {
    from_port   = 0
    to_port     = 0
    protocol    = "-1"
    cidr_blocks = ["0.0.0.0/0"]
  }

  tags = {
    Name = var.KKE_sg
  }
}

terraform init
# or apply forcefully without creating plan and applying it
terraform apply -auto-approve
