How to connect to an S3 bucket using a role ARN is C#

Question

I was using AccessKeyId and secret to connect and manage my private S3 bucket, used by my application.

Devops is saying I need to use a role they have created for me specifically for this use case to eliminate the need for access and secret keys.

How do I assume a role to manage this S3 bucket access in my C# code?

I would think a role is created, a user is assigned that role. Using access/key you assume that user's rights and then you connect to AWS services.

Am I missing something?

Answer 1

A role is a short-term credentialed way of assigning privileges, normally to a service like Lambda, or an EC2 instance; you should assign the role you have been created to the instance from which you are accessing your S3 bucket.
