问题
I read this article about how to implement the credential rotation, I know I could just configure this in 'Edit rotation configuration' option, but the thing is my current secret is in use, and I notice that it says 'Enable automatic rotation - Recommended when your applications are not using this secret yet', how can I enable the rotation then? My database is using RDS Aurora MySQL engine and I want it to rotate every 7 days.
I also read this document, does it mean I must have an IAM role with full access to secret manager? Is the Lambda function compulsory for configuring credential rotation?
I also followed this doc, in the Phrase 3, step 4, the screenshot looks different to mine, I don't have the option 'Use the secret that I provided in step 1', I have something like this: In the screenshot above, it says 'Use this option if you are storing a superuser.' How do I know if I'm storing a superuser?
I'm new to AWS, messing around for a whole morning and read lots of documents, still a bit confused, can someone tell me what's the best way to do this, can someone point me to a step-by-step tutorial or something like that, any suggestions will be appreciated.
