Stork is the Portworx’s storage scheduler for Kubernetes that helps achieve even tighter integration of Portworx with Kubernetes. It allows users to co-locate pods with their data, provides seamaless 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 componenets run in HA mode with 3 replicas by default.

Install

Install using the Portworx spec generator

When installing Portworx through the Portworx spec generator page in PX-Central, you can select Stork to be installed along with Portworx.

If you are using curl to fetch the Portworx spec, you can add stork=true to the parameter list to include Stork specs in the generated file.

Manual install

If you want to install Stork manually, you can follow the steps mentioned on the Stork project page

Using Stork with your applications

To take advantage of the feature of Stork, you need to specify it as the scheduler to be used when creating your applications. This can be done by adding the schedulerName to your application.
