AWS Deployment Examples

Set of examples to demonstrate the various ways applications can be deployed on AWS using AWS CDK.

Prerequisites

  1. Node.js 20.x
  2. direnv
  3. curl
  4. httpie (optional - only needed for the domain configuration script ./scripts/delegate-subdomain.sh)
  5. AWS CLI with account setup. (https://www.granted.dev is a great tool for switching profiles.)
  6. aws-cdk and yalc: npm i -g aws-cdk yalc. Yalc is a tool to work easily with npm packages locally.

Initial setup

  • Clone the repository. It's a monorepo with application projects in the packages folder.
  • Install dependencies.
    • Root folder: npm i
    • Install dependencies of all the projects: npm i -ws
  • The common-constructs project is an aws cdk library project with custom resources and common constructs.
    • Build the project: npm run build -w common-constructs
    • Publish it to yalc: npm run yalc:publish -w common-constructs
  • Create .env. The env-example file can be used as a template for it.
  • Domain setup
    • I use Cloudflare as my DNS provider and wanted to delegate only a sub-domain to Route53. The script ./scripts/delegate-subdomain.sh does that.
    • Update the .env file with necessary information.
  • OIDC authentication:
    • Create Google credentials for OIDC authentication.
    • Once created, run the script ./scripts/create-google-secret.sh to create a AWS Secrets Manager secret for Google client secret.
    • Update .env file with Google Client Id and ARN of the secret.

Examples
