How to run a zero downtime application in kubernetes StatefulSet

7/2/2018

I would like to run a stateful application (performs read/ write operations into a specific folder) in Kubernetes without a single instance dependency.

Can I use statefulset for this requirement.
Is it necessary to use a shared file system (eg: GFS, EFS...)?
If yes, does it affect my application's performance.
