Portworx is a software defined persistent storage solution designed and purpose built for applications deployed as containers, via container orchestrators such as Kubernetes, Marathon and Swarm. It is a clustered block storage solution and provides a Cloud-Native layer from which containerized stateful applications programmatically consume block, file and object storage services directly through the scheduler.
In this tutorial, you will learn how to deploy a 3 node Portworx Cluster.
