aws-sdk-go-v2 VS chamber

It turns out that the AWS SDK for go, aws-sdk-go-v2, released some breaking changes that are unrelated to S3 Express One Zone. You can read more about these changes here.

AWS S3 official documentation AWS S3 official examples

assume_role_with_mfa is a handy small MFA GUI tool from Cristian Magherusan-Stanciu designed to be used as credential_proces for AWS CLI configuration profiles. This is a workaround for the official AWS MFA setup, that works for the CLI but does not work for the Go SDK, as reported at aws-sdk-go-v2/#2356.

In this blog post, you will be using the aws-lambda-go library along with the AWS Go SDK v2 for an application that will process records from an Amazon SNS topic and store them in a DynamoDB table.

This blog post is for folks interested in learning how to use Golang and AWS Lambda to build a serverless solution. You will be using the aws-lambda-go library along with the AWS Go SDK v2 for an application that will process records from an Amazon Kinesis data stream and store them in a DynamoDB table. But that's not all! You will also use Go bindings for AWS CDK to implement "Infrastructure-as-code" for the entire solution and deploy it with the AWS CDK CLI.

The trouble with importing modules from within the same repository is that Go modules won't be able to work out where to download them from. The require directives I mentioned are used extensively by aws-sdk-go-v2 if you're interested in an example.

You may prefer https://github.com/aws/aws-sdk-go-v2 .

I ran into it by switching from aws-sdk-go to aws-sdk-go-v2 and the binary jumped from 27Mb to 66Mb [1]

Granted fully featured app will likely use all of the module's code so it's not a factor.

Chamber takes an opinionated view on AWS Parameter store as compared to ssmsh

Building on this I’ve found https://github.com/segmentio/chamber to be super useful

For secrets, the PaaS platform (Github Actions, Fly.io, etc.) I usually use has a method that works with environment variables. If I need something custom on AWS, then I use Chamber backed by AWS KMS.

We use Chamber (https://github.com/segmentio/chamber) to do this for us. Bring it into your image and use the environment variables as necessary. Some applications support using environment variables natively, you might need to add a script to write them into your config files.

You can take a look at some code I wrote a while back to do this if you want examples https://github.com/segmentio/chamber/blob/master/store/ssmstore.go .

We use AWS Parameter Store and segmentio/chamber.

https://github.com/segmentio/chamber is nice with parameter store, ive used it in the past.

Use Chamber.

For interacting with SSM, I would recommend using https://github.com/segmentio/chamber. You could add something to your user-data script that uses chamber to load a config file (chamber export is one way to do it) from SSM on startup. You could also use Systems Manager to enable you to do a "hot reload" of sorts by sending a command to your server to run the chamber command and restart your application.
