microk8s kubernetes how to install OpenEBS
This is the official guide here from OpenEBS.
Step 1.) Make sure you have the right version.
As of this time 2025-04, we need Kubernetes/Microk8s version 1.23 or higher (note this will continue to increment higher).
Usually a good sign of having the wrong/old version is that you will encounter namespace and other errors:
error: unknown flag: --namespace
Step 2.) Enable Helm
microk8s enable helm
Step 3.) Get OpenEBS repo & update
microk8s helm repo add openebs https://openebs.github.io/openebs
microk8s helm repo update
Hang tight while we grab the latest from your chart repositories...
...Successfully got an update from the "openebs" chart repository
Update Complete. ⎈Happy Helming!⎈
Step 4.) Install OpenEBS
microk8s helm install openebs --namespace openebs openebs/openebs --create-namespace

NAMESPACE: openebs
STATUS: deployed
REVISION: 1
NOTES:
Successfully installed OpenEBS.
Check the status by running: kubectl get pods -n openebs
The default values will install both Local PV and Replicated PV. However,
the Replicated PV will require additional configuration to be fuctional.
The Local PV offers non-replicated local storage using 3 different storage
backends i.e Hostpath, LVM and ZFS, while the Replicated PV provides one replicated highly-available
storage backend i.e Mayastor.
