Ceph Operator Helm Chart

Installs rook to create, configure, and manage Ceph clusters on Kubernetes.

Introduction

This chart bootstraps a rook-ceph-operator deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

• Kubernetes 1.13+
• Helm 3.x

See the Helm support matrix for more details.

Installing

The Ceph Operator helm chart will install the basic components necessary to create a storage platform for your Kubernetes cluster.

1. Install the Helm chart
2. Create a Rook cluster.

The helm install command deploys rook on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation. It is recommended that the rook operator be installed into the rook-ceph namespace (you will install your clusters into separate namespaces).

Rook currently publishes builds of the Ceph operator to the release and master channels.

Release

The release channel is the most recent release of Rook that is considered stable for the community.

helm repo add rook-release https://charts.rook.io/release
kubectl create namespace rook-ceph
helm install --namespace rook-ceph rook-ceph rook-release/rook-ceph

Development Build

To deploy from a local build from your development environment:

1. Build the Rook docker image: make
2. Copy the image to your K8s cluster, such as with the docker save then the docker load commands
3. Install the helm chart:

cd cluster/charts/rook-ceph
kubectl create namespace rook-ceph
helm install --namespace rook-ceph rook-ceph .

Uninstalling the Chart

To see the currently installed Rook chart:

helm ls --namespace rook-ceph

To uninstall/delete the rook-ceph deployment:

helm delete --namespace rook-ceph rook-ceph

The command removes all the Kubernetes components associated with the chart and deletes the release.

After uninstalling you may want to clean up the CRDs as described on the teardown documentation.

Configuration

The following tables lists the configurable parameters of the rook-operator chart and their default values.

* For information on what to set agent.flexVolumeDirPath to, please refer to the Rook flexvolume documentation

* * agent.mounts should have this format mountname1=/host/path:/container/path,mountname2=/host/path2:/container/path2

* * * nodeAffinity and *NodeAffinity options should have the format "role=storage,rook; storage=ceph" or storage=;role=rook-example or storage=; (checks only for presence of key)

Command Line

You can pass the settings with helm command line parameters. Specify each parameter using the --set key=value[,key=value] argument to helm install.

Settings File

Alternatively, a yaml file that specifies the values for the above parameters (values.yaml) can be provided while installing the chart.

helm install --namespace rook-ceph rook-ceph rook-release/rook-ceph -f values.yaml

For example settings, see values.yaml
