  Sometimes you want to run your lambda function deployed as a cloudformation stack locally for testing purposes but you don’t want to hard code any of the underlying resources into your environment. These resources might be things like DynamoDB tables, SNS topics or SQS urls. Their names aren’t hard coded, and shouldn’t be hard coded otherwise you have a singleton stack. Sometimes you’re just a bit too impatient to spin everything up using the SAM cli, and don’t want to debug docker issues, so this helps.

• Building a Go Application Inside of AWS CloudShell 29 September 2022

  I’ve been learning a little bit of golang as of late, and I wanted to run it on AWS Lambda. I had a couple errors come up about my libc, and learned that I need to build my applications on Amazon Linux, so they can run on lambda. I didn’t want to set up a CodeBuild just to play with a few toy example programs or setup a couple docker containers. In fact we don’t even need to since AWS provides CloudShell, a complete shell environment available to every user of an AWS account.

  I have a DynamoDB table that is automatically exported as JSON to compute some reports. I wanted to automate the table creation process and load steps. Amazon Athena allows querying from raw files stored on S3, which allows reporting when a full database would be too expensive to run because it’s reports are only needed a low percentage of the time or a full database is not required. It’s billed by the amount of data scanned, which makes it relatively cheap for my use case.

  I always wanted to have search on my site, but it’s statically hosted, so I can’t have any dynamic content on it. I recently resolved that by creating a little tiny lambda function on AWS that queries a SQLite database hosted on S3. Here I’ll walk you through how I created the back-end for it, and in some later posts I’ll include details on calculating the cost.
