Support for S3 Buckets in Different Accounts?

[EdKingscote]

I'm looking at running this in a self-hosted K8s environment but desire to access different S3 buckets that are spread across multiple AWS accounts, which means each will need a unique access/secret key combination.

I've spent a fair bit of time looking around, but it isn't clear to me whether this is achievable. The only thing I can envisage right now is using mountOptions on the Persistent Volume definition to be able to select the right credential profile, but I can't see a way to provide the profiles needed.

Many thanks
