This directory modifies the basic Spring Boot application to work inside Lambda with SnapStart enabled.

Copy etc/environment.template to etc/environment.sh and update accordingly.

• PROFILE: your AWS CLI profile with the appropriate credentials to deploy
• BUCKET: your configuration bucket
• P_NAME: naming prefix for resources
• P_STAGE: stage for API Gateway
• P_FN_MEMORY: memory configuration in MB
• P_FN_TIMEOUT: timeout configuration in seconds
• P_FN_ALIAS_NAME: name to use for the function alias
• P_FN_SNAPSTART_APPLY_ON: None to disable SnapStart or PublishedVersions to enable it

For the infrastructure stack, update the following accordingly.

• P_VPC_ID: your VPC id
• P_HOSTEDZONE_DOMAIN: root domain name for the private hosted zone
• P_DOMAINNAME: domain name to be used for your certificate and alias for the load balancer.

For your hosted zone domain, you'll want to create a private domain off the public domain that you own. For example, heeki.cloud is the public hosted zone that is owned with this eample. Thus, P_HOSTEDZONE_DOMAIN is then configured as internal.heeki.cloud. For your domain name, you'll create an ACM certificate to be used as a custom domain name.

Deploy the infrastructure resources using makefile: make infrastructure

After completing the deployment, update the following outputs:

• O_HOSTEDZONE_ID: output hosted zone id
• O_CERT_ARN: output certificate ARN

Deploy the DynamoDB table: make ddb

After completing the deployment, update the following outputs:

• O_TABLE_ARN: output DynamoDB table ARN

Deploy the Lambda and API Gateway resources: make lambda

After completing the deployment, update the following outputs:

• O_FN: output Lambda function id
• O_API_ENDPOINT: output API Gateway endpoint URL, e.g. https://<api_id>.execute-api..amazonaws.com/

To create a customer record and retrieve a list of all customer records:

mkdir tmp && cat > tmp/customer.json << EOF

    "phone_number": "+15551234567",
    "phone_number_verified": true
}

curl -s -XPOST -H "content-type:application/json" -d @tmp/customer.json https://<api_id>.execute-api.<region>.amazonaws.com/<stage>/customer
curl -s -XGET https://<api_id>.execute-api.<region>.amazonaws.com/<stage>customer
