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.
Task 2: Create an EC2 instance with server installed.
Task 3: Access your website.
Prerequisites:
Create IAM user and attach policy click here
Install and configure AWS CLI click here
Task 1:
To create a security group, write the below code:
terraform {
required_providers {
aws = {
source = "hashicorp/aws"
version = "~> 4.16"
}
}
required_version = ">= 1.2.0"
}
provider "aws" {
region = "us-east-1"
}
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"]
}
}
Run terraform init and then terraform apply to create a security group.
Task 2:
To create ec2 instance with server installed, add below code in the existing main.tf file.
resource "aws_instance" "web_server" {
ami = "ami-0c7217cdde317cfec"
instance_type = "t2.micro"
key_name = "my-linux-key"
security_groups = [aws_security_group.web_server.name]
user_data = <<-EOF
#!/bin/bash
echo "<html><body><h1>Welcome to my website!</h1></body></html>" > index.html
nohup python3 -m http.server 80 &
EOF
}
You need to change key_name and ami as per your requirements.
Run terraform apply to create an instance.
Task 3:
Access your website.
Copy the public ip address of your instace and paste it in any browser. You may need to wait till status check pass successfully.
