Example Go process with JSON HTTP API and SQS consumer loop

Highlights:

• One Go process
• Super simple JSON HTTP API implementation
• SQS consumer loop, with per-message handler
• Backoff for the consumer loop
• Structured logs
• Graceful shutdown, with limit
• Docker Compose and LocalStack dev setup
• AWS setup with Terraform
• S3 bucket -> SQS notification to poke the consumer

docker compose up should be enough to get it going.

Trigger a SQS message by creating a new S3 file, e.g. N=a; echo $N | docker-compose run --rm -T localstack-cli s3 cp - s3://outbox/$N.
