Sure cloud custodian extensible, its supports multiple cloud providers today (aws, gcp, azure) with work in progress on Kubernetes. The core plugin mechanism (registries) are used across every part, cloud providers, resources in those providers, and filters and actions for resources. As an example have a look at the Kubernetes provider https://github.com/cloud-custodian/cloud-custodian/tree/mast...

We've considered digital ocean support, and I use DO as well, but the primary use cases custodian serves around governance/compliance, security, cost optimization haven't seemed as needed with DO across our user population (ie hasn't been requested), so its not been as high a priority on the roadmap atm, that said its a community project so contributions welcome.

All that said, if your just looking for a periodic dump to a datastore, then perhaps cloud marker is going to be a better fit.
