Terraform Java snapstart Lambda template

This is a template for enabling the craziest architecture ever:

• Easy packaing of ANY horrible (Spring Boot?) java-app inside AWS Lambda
• Snapstart for enabling lighting-fast startup
• Step Functions for performing orchestration of 1-many lambdas (functions from one or more apps)
• API Gateway for http access
• Terraform for easy deployment

NOTE: Auhtentication || Security || Batteries NOT INCLUDED

Terraform config example:

Add file ./eu-west-1.tfvars

deployment_prefix = "LambdaTesting"

aws_region = "eu-west-1"

lambda_payload_filename = "../target/lambda-template-0.1.0.jar"

Deployment

mvn clean package

cd terraform

terraform init

terraform apply -var-file=eu-west-1.tfvars #DEPLOY TO AWS:

Invoking

curl "$(terraform output -raw base_url)/your_bath"

Cleanup

terraform destroy -var-file=eu-west-1.tfvars

Setting up bucket-storage for Terraform state

terraform {

backend "s3" {

bucket = "lambda-demo-terraform"

key = "lambda-dev.tfstate"

region = var.aws_region

dynamodb_table = "lambda-dev-terraform-state"

}

}
