Storage in Kubernetes is hard, complicated, and messy. Configuring volumes, mounts, and persistent volumes claims and getting it right can be a challenge. It's also challenging to manage that storage and replicate it across all your Kubernetes clusters. It's also been very challenging to do this on bare metal, outside of a cloud provider. That's where Longhorn comes. Longhorn is an open source, a CNCF distributed block storage system for Kubernetes. It comes with a UI, backups, snapshots, and cluster disaster recovery and it does all this with or without Rancher. Rancher is NOT a requirement.
