2 tier Application deployment through terraform

🖥️ Installation

Prerequisite:

• Terraform installed
• AWS CLI installed
• AWS IAM user with administrative access

👉 let install dependency to deploy the application

cd main
terraform init 

Note: we need public key and private key for our server so follow below procedure.

cd modules/key/
ssh-keygen.exe 

above command ask for key name then give client_key it will create pair of keys one public and one private. you can give any name you want but then you need to edit the terraform file

edit below file according to your configuration

vim main/backend.tf

add below code in book_shop_app/backend.tf

terraform {
  backend "s3" {
    bucket = "BUCKET_NAME"
    key    = "backend/terraform.tfstate"
    region = "us-east-1"
    dynamodb_table = "dynamoDB_TABLE_NAME"
  }
}

Lets setup the variable for our Infrastructure

create one file with the name of terraform.tfvars

vim main/terraform.tfvars

add below contents into main/terraform.tfvars file

REGION                  = ""
PROJECT_NAME            = ""
VPC_CIDR                = ""
PUB_SUB_1_A_CIDR        = ""
PUB_SUB_2_B_CIDR        = ""
PRI_SUB_3_A_CIDR        = ""
PRI_SUB_4_B_CIDR        = ""
PRI_SUB_5_A_CIDR        = ""
PRI_SUB_6_B_CIDR        = ""
DB_USERNAME             = ""
DB_PASSWORD             = ""
CERTIFICATE_DOMAIN_NAME = ""
ADDITIONAL_DOMAIN_NAME  = ""
