Portworx Stork

Portworx Stork is a storage scheduler for Kubernetes that helps achieve tighter integration of Portworx with Kubernetes. It allows users to co-locate pods with their data, provides seamless migration of pods in case of storage errors, and makes it easier to create and restore snapshots of Portworx volumes. Stork consists of 2 components, the Stork scheduler and an extender. Both of these components run in HA mode with 3 replicas by default. When Portworx is installed using the Portworx Enterprise Cluster Spec from Portworx Central , Stork is installed by default.

This topic describes how to verify Portworx Stork installation and also explains how to upgrade Stork.
