You could use Hephy Workflow (you might have heard of Deis Workflow?) on DOK8S to do that.
This is an open-source fork of Deis Workflow.
We're hoping to add support for Digital Ocean's Kubernetes and ancillary services like storage in the next release. Preliminary testing indicates that it is very much possible. The only dependencies of a prod Workflow deployment are, any compliant Kubernetes, Load Balancers, and an S3-api compatible storage, all of which are available on DO now.
The latest Hephy release does not yet support general S3-api compatibility with arbitrary S3 providers like DO, but DigitalOcean is our first target platform for expanding the supported offerings. The pull requests are open right now.
(Currently supported platforms include GCP/GKE, Amazon, and Azure AKS.)
