We have been using DO for all development/testing activities. We have successfully deployed a scalable staging environment using Docker Swarm Mode. The only glitch is that we can not scale the application container across multiple swarm nodes as these instances can not share a persistence storage (volumes) across the nodes. There are many suggestions from unofficial sources to use NFS, Flocker, GlusterFS, etc. But there is no clear direction / guideline from DigitalOcean.
Without an officially supported solution for shared storage from DO, we have to regretfully leave DO and join the AWS band wagon.
