Deploy Mayastor

Overview

Before deploying and using Mayastor please consult the Known Issues section of this guide.
The steps and commands which follow are intended only for use in conjunction with Mayastor version(s) 2.1.x and above.

Installation via helm

The Mayastor Helm chart now includes the Dynamic Local Persistent Volume (LocalPV) provisioner as the default option for provisioning storage to etcd and Loki. This simplifies storage setup by utilizing local volumes within your Kubernetes cluster. For etcd, the chart uses the mayastor-etcd-localpv storage class, and for Loki, it utilizes the mayastor-loki-localpv storage class. These storage classes are bundled with the Mayastor chart, ensuring that your etcd and Loki instances are configured to use openEbs localPV volumes efficiently. /var/local/{{ .Release.Name }} paths should be persistent accross reboots.
