Flocker vs KubeDB: What are the differences?
Developers describe Flocker as "Run your databases in Docker and make them as portable as the rest of your app". Flocker is a data volume manager and multi-host Docker cluster management tool. With it you can control your data using the same tools you use for your stateless applications. This means that you can run your databases, queues and key-value stores in Docker and move them around as easily as the rest of your app. On the other hand, KubeDB is detailed as "Kubernetes ready production-grade Databases". With the introduction of StatefulSet, it became easy to run a docker container for any database. But what about monitoring, taking periodic backups, restoring from backups or cloning from an existing database? KubeDB is a framework for writing operators for any database...
Flocker and KubeDB can be categorized as "Container" tools.
