Infrastructure-As-Code Using Terraform:

The goal of this pipeline is to implement the following infrastructure using terraform:

Table of Content:

AWS Provider:

export AWS_ACCESS_KEY_ID="anaccesskey"

export AWS_SECRET_ACCESS_KEY="asecretkey"

export AWS_DEFAULT_REGION="us-west-2"

provider "aws" {}

VPC:

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

  tags = {
    Name = "main"
  }
}

Internet Gateway on VPC:

# Main Internet Gateway
resource "aws_internet_gateway" "gw" {
  vpc_id = aws_vpc.main.id

  tags = {
    Name = "main_internet_gateway"
  }
}

Two Private Subnets:

# Private Subnets
resource "aws_subnet" "private_subnet_1" {
  vpc_id     = aws_vpc.main.id
  cidr_block = "10.0.3.0/24"

  tags = {
    Name = "private_subnet_1"
  }
}


resource "aws_subnet" "private_subnet_2" {
  vpc_id     = aws_vpc.main.id
  cidr_block = "10.0.4.0/24"
  
  tags = {
    Name = "private_subnet_2"
  }
}

Private Route Table:

# Private Route Table
resource "aws_route_table" "private_route_table" {
  vpc_id = aws_vpc.main.id

  tags = {
    Name = "private_route_table"
  }
}

Private Route Table Assiociations:

# Route-Table Associations
resource "aws_route_table_association" "rt_private_subnet_1" {
  subnet_id      = aws_subnet.private_subnet_1.id
  route_table_id = aws_route_table.private_route_table.id
}


resource "aws_route_table_association" "rt_private_subnet_2" {
  subnet_id      = aws_subnet.private_subnet_2.id
  route_table_id = aws_route_table.private_route_table.id
}

Two Public Subnets:

# Public Subnets
resource "aws_subnet" "public_subnet_1" {
  vpc_id     = aws_vpc.main.id
  cidr_block = "10.0.1.0/24"
  map_public_ip_on_launch = true

  tags = {
    Name = "public_subnet_1"
  }
}


resource "aws_subnet" "public_subnet_2" {
  vpc_id     = aws_vpc.main.id
  cidr_block = "10.0.2.0/24"
  map_public_ip_on_launch = true

  tags = {
    Name = "public_subnet_2"
  }
}

Public Route Table:

# Public Route Table
resource "aws_route_table" "public_route_table" {
  vpc_id = aws_vpc.main.id

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


  tags = {
    Name = "public_route_table"
  }
}

Public Route Table Assiociations:

# Route-Table Associations
resource "aws_route_table_association" "rt_pub_subnet_1" {
  subnet_id      = aws_subnet.public_subnet_1.id
  route_table_id = aws_route_table.public_route_table.id
}


resource "aws_route_table_association" "rt_pub_subnet_2" {
  subnet_id      = aws_subnet.public_subnet_2.id
  route_table_id = aws_route_table.public_route_table.id
}
