Thanks :) We are using Nebula[1] to provide an encrypted private meshed network per project, so each project have it's own network range. We have automated that with a rest api and have published it as an open source project[2]

It's really cool because you have out of the box a private network across all cloud providers and also works for on-premise deployments
