Install SUSE® Storage Using Helm

Prerequisites

Kubernetes cluster: Ensure that each node fulfills the installation requirements.
Your workstation: Install Helm v3.0 or later.

This script can be used to check the Longhorn environment for potential issues.

Installation

Note:

The initial settings for Longhorn can be found in customized using Helm options or by editing the deployment configuration file.

For Kubernetes < v1.25, if your cluster still enables Pod Security Policy admission controller, set the helm value enablePSP to true to install longhorn-psp PodSecurityPolicy resource which allows privileged Longhorn pods to start.

Add the Longhorn Helm repository:

helm repo add longhorn https://charts.longhorn.io

Fetch the latest charts from the repository:
```
helm repo update
```

Install Longhorn in the longhorn-system namespace.

 helm install longhorn longhorn/longhorn --namespace longhorn-system --create-namespace --version 1.7.0

To confirm that the deployment succeeded, run:

 kubectl -n longhorn-system get pod

The result should look like the following:
