Go Hello World using AWS CDK 2

Environment variables in .github/workflows

For example using DNS validation with wildcard *.dabase.com

AWSCERT="arn:aws:acm:ap-southeast-1:407461997746:certificate/87b0fd84-fb44-4782-b7eb-d9c7f8714908"
DOMAIN="hello.dabase.com"

CI/CD deployment; you need to adjust role-to-assume for the workflow to work, once setup you avoid the need to setup AWS_SECRET_ACCESS_KEY credentials.

To deploy to the cloud

npx aws-cdk@2.x deploy

To develop locally with a live reloader

cd src
go install github.com/cosmtrek/air@latest
PORT=3000 air

Why?

There are many ways to deploy a Go application to the AWS Cloud. I've explored them all.

EC2

Copy across the Go binary and put it behind an ALB or Caddy.

Awkward and isn't serverless.

Make a Docker image and deploy with Kubernetes

Have you lost your mind? This is incredibly complex and expensive way to deploy a Go application to the Cloud.

Good luck to you and your team.

And it's not serverless.

AWS Serverless Application Model (SAM)

https://github.com/kaihendry/aws-sam-gateway-example

An efficient usage of AWS native Cloudformation that requires Python tooling such as https://github.com/aws/aws-sam-cli

Apex Up

Easiest though proprietary https://apex.sh/up/

Terraform

Very awkward and slow to deploy and requires extra tooling.

AWS CDK

Keep everything in Go, including the Infrastructure as Code.
