An open question here: Should we add into the EKS values file the equivalent value to set gp2 as the StorageClass? Pros: it will "just work" for users of EKS 1.30+. Cons: it's a default change which may not work for users who have removed this StorageClass.

I like the idea of defaulting to a storageClass that "just works" if one is not already defined. As you've mentioned I think it can get quite complicated for existing users if they are already on a different storageClass. Maybe for now it's best to doc as a troubleshooting step?

[chipzoller]

I did at least document it here: https://docs.kubecost.com/install-and-configure/install/provider-installations/aws-eks-cost-monitoring#prerequisites-1

Perfect! I'd be open to attempting a gp2 default. My biggest concern would b that swapping storageClasses may be a destructive operation on some people's PVs? Not 100% sure.

Adding a default value sounds good to me. Does that work for you, @jessegoodier ?
