Taming Distributed Stateful Pets With Kubernetes

So you've mastered Kubernetes for scheduling and scaling your stateless applications. Your pager has been quieter, life is good. But what about the carefully configured database clusters running on expensive dedicated infrastructure? (And the expensive sysadmin you're paying to maintain it!).

In Kubernetes, there are now many of the building blocks needed to help herd database ‘Pets’, alongside the stateless applications in your cluster. In this talk, we'll explain how we use these features, including StatefulSet and dynamic volume provisioning, to manage the lifecycle of distributed and secure Cassandra clusters for cloud and bare-metal environments with the open source project Navigator.

Building on the Kubernetes API machinery, with custom API server and controllers, a ‘Navigator’ and sidecar ‘Pilots’ codify and automate many of the processes that would previously have been performed by a database administrator. Bootstrap, scale-up and safe scale-down, health checks, load balancing and more. Learn how Navigator uses Kubernetes as its kernel to make it as easy to deploy and manage stateful systems as stateless applications.
