wildrydes_terraform

WildRydes (Serverless Web Application) with Terraform in AWS

Introduction

WildRydes application is from one of the AWS getting started projects.

Manual steps to build and deploy is avaliable here

The application uses the following AWS services

AWS Lambda

Amazon API Gateway

Amazon S3

Amazon Dynamodb

Amazon Cognito

Application gets deployed in eu-west-2 region by default

Terraform is used to build the Web App on AWS

Usage

Remote State

• S3 is used as a remote storage for your infrastructure state. So you will need to have an existing bucket which can be used to store the state remotely.

• Update bucket name in remote_state.tf

# --------------------------------------------------
# Remote State for our application 
# --------------------------------------------------
terraform {
  backend "s3" {
    bucket         = "<your_state_bucket_here>"
    key            = "dev-sandbox/wildrydes_terraform/terraform.tfstate"
    region         = "eu-west-2"
    encrypt        = true
    dynamodb_table = "terraform"
  }
}

• S3 bucket to upload the website code. Bucket names are globally unique so you would need to update your bucket in variables_input.tf

variable "s3-bucket-name" {
    default = "<your_s3_code_bucket_here>"
}

Terraform

Change the current directory to wildrydes_terraform and execute the following

$ terraform init
$ terraform plan
$ terraform apply

After apply, you will get 3 outputs.

Apply complete! Resources: 21 added, 0 changed, 0 destroyed.

Outputs:

lambda_base_url = https://1lcyeokpe6.execute-api.eu-west-2.amazonaws.com/Test
user_pool_client_id = 4mkt3h62iq79628019d7r41787
user_pool_id = eu-west-2_A4HfohzmL

Update the values in src_webapp\js\config.js

window._config = {
    cognito: {
        userPoolId: '<user_pool_id_here>', 
        userPoolClientId: '<user_pool_client_id_here>', 
        region: 'eu-west-2'
    },
    api: {
        invokeUrl: '<lambda_base_url_here>'
    }
};

upload the code from src_webapp to s3 bucket

WildRydes Web Application should be avaliable at

http://<your_s3_code_bucket_here>.s3-website.eu-west-2.amazonaws.com/

Destroy your resources as it may cost you money
