iEHR Infra

CDK scripts to setup the full stack:

• S3 + CloudFront for static site
• VPC for private network
• Fargate for backend server
• Aurora RDS for database

Install

iEHR uses npm workspaces for a monorepo configuration.

See Developer Setup for cloning the repository and installing dependencies.

Deploy

First, create a configuration file.

Next, it is strongly recommended to diff changes before deploying.

npx cdk diff -c config=my-config.json

npx cdk deploy -c config=my-config.json

Destroy

npx cdk destroy

Storage

Based on:

The CloudFront distribution requires a public key for signature verification.

Generate a 2048 bit RSA key:

openssl genrsa -des3 -out private.pem 2048

Export the public key to a file:

openssl rsa -in private.pem -outform PEM -pubout -out public.pem

Open the public.pem file and ensure that it starts with -----BEGIN PUBLIC KEY-----. This is how you know that this file is the public key of the pair and not a private key.

Add the public key to the CDK infrastructure configuration.

Add the private key to the server configuration settings (JSON, AWS Parameter Store, etc).
