Hi Do you guys have any general examples of creating aws aurora cluster and instances via pulumi aws classic? Thanks

There's some in the docs here: https://www.pulumi.com/registry/packages/aws/api-docs/rds/clusterinstance/

Nothing about using a vpc

I think you have to setup a subnet group, it's not much more. https://www.pulumi.com/registry/packages/aws/api-docs/rds/subnetgroup/
