Day 65 - Working with Terraform Resources 🚀

Yesterday, we saw how to create a Terraform script with Blocks and Resources. Today, we will dive deeper into Terraform resources.

Understanding Terraform Resources

A resource in Terraform represents a component of your infrastructure, such as a physical server, a virtual machine, a DNS record, or an S3 bucket. Resources have attributes that define their properties and behaviors, such as the size and location of a virtual machine or the domain name of a DNS record.

When you define a resource in Terraform, you specify the type of resource, a unique name for the resource, and the attributes that define the resource. Terraform uses the resource block to define resources in your Terraform configuration.

Task 1: Create a security group

To allow traffic to the EC2 instance, you need to create a security group. Follow these steps:

In your main.tf file, add the following code to create a security group:

resource "aws_security_group" "web_server" {
  name_prefix = "web-server-sg"

  ingress {
    from_port   = 80
    to_port     = 80
    protocol    = "tcp"
    cidr_blocks = ["0.0.0.0/0"]
  }
}
