secrets-store-csi-driver VS aws-secrets-manager-rotation-lambdas

I'm not a fan of this approach. I think the Secrets Store CSI Driver (https://secrets-store-csi-driver.sigs.k8s.io/) has a better approach.

Secret Store CSI Driver is what we're playing with now. Pretty excellent.

If you deploy on k8s, keep your eye on https://secrets-store-csi-driver.sigs.k8s.io/

Considering the major limitations of using Kubernetes Secrets, there are many new approaches being developed by the Kubernetes community. Kubernetes SIGs like the Secrets Store CSI Driver and solutions like the external secrets operator that works with third-party secret managers, and options to seal secrets through tools like bitnami’s sealed-secrets. To skip the tools and move directly to best practices, click here.

Just to clarify, CSI secret driver is from cncf not Microsoft. Only msft piece is the portion that integrates with key vault. https://secrets-store-csi-driver.sigs.k8s.io/

The Secrets Store CSI Driver is a native upstream Kubernetes driver that can be used to abstract where the secret is stored from the workload. If you want to use a cloud provider's secret manager without exposing the secrets as Kubernetes Secret objects, you can use the CSI Driver to mount secrets as volumes in your pods. This is a great option if you use a cloud provider to host your Kubernetes cluster. The driver supports many cloud providers and can be used with different secret managers.

If you want security they are both bad, use something like the secret manager of your choice API directly in your app or https://secrets-store-csi-driver.sigs.k8s.io/ this will keep the actual secrets out of etcd and env vars and give you more security

Create a new Lambda function that will handle the rotation - here is a template https://github.com/aws-samples/aws-secrets-manager-rotation-lambdas/blob/master/SecretsManagerRDSMySQLRotationMultiUser/lambda_function.py - I created it in a separate folder within the same repository. If you are like me, new to using Python, you could use this helpful guide:https://docs.aws.amazon.com/lambda/latest/dg/python-package.html.

One extra benefit of using Secrets Manager is that you can enable secret rotation. You can find reference implementations for the rotation lambda here https://github.com/aws-samples/aws-secrets-manager-rotation-lambdas

I would like to deploy SecretsManagerRDSPostgreSQLRotationMultiUser lambda with terraform; meaning I would store source code of lambda linked above in my repository and use terraform to package it into zip file, including dependencies and then upload it to AWS.
