This document describes persistent volumes in Kubernetes. Familiarity with volumes, StorageClasses and VolumeAttributesClasses is suggested. Introduction Managing storage is a distinct problem from managing compute instances. The PersistentVolume subsystem provides an API for users and administrators that abstracts details of how storage is provided from how it is consumed. To do this, we introduce two new API resources: PersistentVolume and PersistentVolumeClaim. A PersistentVolume (PV) is a...| Kubernetes
You can constrain a Pod so that it is restricted to run on particular node(s), or to prefer to run on particular nodes. There are several ways to do this and the recommended approaches all use label selectors to facilitate the selection. Often, you do not need to set any such constraints; the scheduler will automatically do a reasonable placement (for example, spreading your Pods across nodes so as not place Pods on a node with insufficient free resources).| Kubernetes
Jobs represent one-off tasks that run to completion and then stop.| Kubernetes

+ / / tl;dr - Finally, the results of the benchmarking. You can find the code on GitLab. There are some issues with the benchmarks but there was enough decent data to make a decision for me at least. As far as which storage plugins I’m going to run, I’m actually going to run both OpenEBS Mayastor and Ceph via Rook on LVM. I look forward to emails from users/corporations/devrel letting me know how I misused their products if I did – please file an issue on GitLab!| vadosware.io
