# OpenEBS LocalPV Provisioner
|
||||
|
||||
[](https://opensource.org/licenses/Apache-2.0)
|
||||
|
||||
|
||||
|
||||
A Helm chart for openebs dynamic localpv provisioner. This chart bootstraps OpenEBS Dynamic LocalPV provisioner deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

## Get Repo Info
|
||||
|
||||
```console
|
||||
helm repo add openebs-localpv https://openebs.github.io/dynamic-localpv-provisioner
|
||||
helm repo update
|
||||
```
|
||||
|
||||
_See [helm repo](https://helm.sh/docs/helm/helm_repo/) for command documentation._
|
||||
|
||||
## Install Chart
|
||||
|
||||
Please visit the [link](https://openebs.github.io/dynamic-localpv-provisioner/) for install instructions via helm3.
|
||||
|
||||
```console
|
||||
# Helm
|
||||
helm install [RELEASE_NAME] openebs-localpv/localpv-provisioner --namespace [NAMESPACE] --create-namespace
|
||||
```
|
||||
|
||||
_See [configuration](#configuration) below._
|
||||
|
||||
_See [helm install](https://helm.sh/docs/helm/helm_install/) for command documentation._
|
||||
|
||||
## Dependencies
|
||||
|
||||
By default this chart installs additional, dependent charts:
|
||||
|
||||
| Repository | Name | Version |
|
||||
|------------|------|---------|
|
||||
| https://openebs.github.io/node-disk-manager | openebs-ndm | 2.1.0 |
|
||||
|
||||
**Note:** Find detailed Node Disk Manager Helm chart configuration options [here](https://github.com/openebs/node-disk-manager/blob/master/deploy/helm/charts/README.md).
|
||||
|
||||
|
||||
To disable the dependency during installation, set `openebsNDM.enabled` to `false`.
|
||||
|
||||
_See [helm dependency](https://helm.sh/docs/helm/helm_dependency/) for command documentation._
|
||||
|
||||
## Uninstall Chart
|
||||
|
||||
```console
|
||||
# Helm
|
||||
helm uninstall [RELEASE_NAME] --namespace [NAMESPACE]
|
||||
```
|
||||
|
||||
This removes all the Kubernetes components associated with the chart and deletes the release.
|
||||
|
||||
_See [helm uninstall](https://helm.sh/docs/helm/helm_uninstall/) for command documentation._
|
||||
|
||||
## Upgrading Chart
|
||||
|
||||
```console
|
||||
# Helm
|
||||
helm upgrade [RELEASE_NAME] [CHART] --install --namespace [NAMESPACE]
|
||||
```
|
||||
|
||||
|
||||
## Configuration
|
||||
|
||||
The following table lists the configurable parameters of the OpenEBS Dynamic LocalPV Provisioner chart and their default values.
|
||||
|
||||
You can modify different parameters by specifying the desired value in the `helm install` command by using the `--set` and/or the `--set-string` flag(s). You can modify the parameters of the [Node Disk Manager chart](https://openebs.github.io/node-disk-manager) by adding `openebs-ndm` before the desired parameter in the `helm install` command.
|
||||
|
||||
In the following sample command we modify `deviceClass.fsType` from the localpv-provisioner chart and `ndm.nodeSelector` from the openebs-ndm chart to only schedule openebs-ndm DaemonSet pods on nodes labelled with `openebs.io/data-plane=true`. We also enable the 'Use OS-disk' feature gate using the `featureGates.UseOSDisk.enabled` parameter from the openebs-ndm chart.
|
||||
|
||||
|
||||
```console
|
||||
helm install openebs-localpv openebs-localpv/localpv-provisioner --namespace openebs --create-namespace \
|
||||
--set-string deviceClass.fsType="xfs" \
|
||||
--set-string openebs-ndm.ndm.nodeSelector."openebs\.io/data-plane"=true \
|
||||
--set openebs-ndm.featureGates.UseOSDisk.enabled=true
|
||||
```
|
||||
|
||||
Sample command to install the provisioner with nodeAffinityLabels "openebs.io/node-affinity-key-1" and "openebs.io/node-affinity-key-2" on the hostpath StorageClass:
|
||||
```console
|
||||
helm install openebs-localpv openebs-localpv/localpv-provisioner --namespace openebs --create-namespace \
|
||||
--set-string hostpathClass.nodeAffinityLabels="{openebs.io/node-affinity-key-1,openebs.io/node-affinity-key-2}"
|
||||
```
|
||||
|
||||
Sample command to install the provisioner with blockDeviceSelectors "openebs.io/block-device-tag=mongo" and "ndm.io/fsType=ext4":
|
||||
```console
|
||||
helm install openebs-localpv openebs-localpv/localpv-provisioner --namespace openebs --create-namespace \
|
||||
--set-string deviceClass.blockDeviceSelectors."openebs\.io/block-device-tag"="mongo" \
|
||||
--set-string deviceClass.blockDeviceSelectors."ndm\.io/fsType"="ext4"
|
||||
```
