Installing Longhorn

Note:

  1. Add the Longhorn Helm repository:

    helm repo add longhorn https://charts.longhorn.io
    
  2. Fetch the latest charts from the repository:

    helm repo update
    
  3. Install Longhorn in the longhorn-system namespace.

    To install Longhorn with Helm 2, use the command:

    helm install longhorn/longhorn --name longhorn --namespace longhorn-system --version 1.4.0
    

    To install Longhorn with Helm 3, use the commands:

    helm install longhorn longhorn/longhorn --namespace longhorn-system --create-namespace --version 1.4.0
    
  4. To confirm that the deployment succeeded, run:

    kubectl -n longhorn-system get pod
    

    The result should look like the following:
