Simple Resource Creation

1. Provider

# Define the provider
provider "aws" {
  region = "us-west-2"  # Specify your desired region
}

1. VPC

# Create a VPC
resource "aws_vpc" "main" {
  cidr_block = "10.0.0.0/16"

  tags = {
    Name = "main-vpc"
  }
}

1. Subnet

# Create a public subnet
resource "aws_subnet" "public" {
  vpc_id                  = aws_vpc.main.id
  cidr_block              = "10.0.1.0/24"
  map_public_ip_on_launch = true

  tags = {
    Name = "public-subnet"
  }
}

1. Internet Gateway

# Create an Internet Gateway
resource "aws_internet_gateway" "main" {
  vpc_id = aws_vpc.main.id

  tags = {
    Name = "main-igw"
  }
}

1. Route Table

# Create a route table
resource "aws_route_table" "public" {
  vpc_id = aws_vpc.main.id

  route {
    cidr_block = "0.0.0.0/0"
    gateway_id = aws_internet_gateway.main.id
  }

  tags = {
    Name = "public-route-table"
  }
}
# Associate the route table with the public subnet
resource "aws_route_table_association" "public" {
  subnet_id      = aws_subnet.public.id
  route_table_id = aws_route_table.public.id
}

1. Security Group

# Create a security group
resource "aws_security_group" "web-sg" {
  vpc_id = aws_vpc.main.id

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

  ingress {
    from_port   = 22
    to_port     = 22
    protocol    = "tcp"
    cidr_blocks = ["0.0.0.0/0"]
  }

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

  tags = {
    Name = "web-sg"
  }
}

1. EC2 Instance

# Create an EC2 instance
resource "aws_instance" "web" {
  ami           = "ami-0c55b159cbfafe1f0"  # Example AMI ID, change it based on your region
  instance_type = "t2.micro"
  subnet_id     = aws_subnet.public.id
  security_groups = [aws_security_group.web-sg.name]

  tags = {
    Name = "web-instance"
  }
}

1. LoadBalancer

# Create a load balancer
resource "aws_lb" "web" {
  name               = "web-lb"
  internal           = false
  load_balancer_type = "application"
  security_groups    = [aws_security_group.web-sg.id]
  subnets            = [aws_subnet.public.id]

  enable_deletion_protection = false

  tags = {
    Name = "web-lb"
  }
}
