    Operator Helm Chart

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


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


    • Kubernetes 1.6+


    If role-based access control (RBAC) is enabled in your cluster, you may need to give Tiller (the server-side component of Helm) additional permissions. If RBAC is not enabled, be sure to set rbacEnable to false when installing the chart.

    # Create a ServiceAccount for Tiller in the `kube-system` namespace
    kubectl -n kube-system create sa tiller
    # Create a ClusterRoleBinding for Tiller
    kubectl create clusterrolebinding tiller --clusterrole cluster-admin --serviceaccount=kube-system:tiller
    # Patch Tiller's Deployment to use the new ServiceAccount
    kubectl -n kube-system patch deploy/tiller-deploy -p '{"spec": {"template": {"spec": {"serviceAccountName": "tiller"}}}}'


    The Rook Operator helm chart will install the basic components necessary to create a storage platform for your Kubernetes cluster. After the helm chart is installed, you will need to 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.

    Rook currently publishes builds to the alpha and master channels. In the future, beta and stable will also be available.


    The alpha channel is the most recent release of Rook that is considered ready for testing by the community.

    helm repo add rook-alpha https://charts.rook.io/alpha
    helm install rook-alpha/rook


    The master channel includes the latest commits, with all automated tests green. Historically it has been very stable, though there is no guarantee.

    To install the helm chart from master, you will need to pass the specific version returned by the search command.

    helm repo add rook-master https://charts.rook.io/master
    helm search rook
    helm install rook-master/rook --version <version>

    For example:

    helm install rook-master/rook --version v0.6.0-156.gef983d6

    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
      helm install --name rook --namespace rook-system .

    Uninstalling the Chart

    To uninstall/delete the rook deployment:

    $ helm delete --purge rook

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


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

    Parameter Description Default
    image.repository Image rook/rook
    image.tag Image tag v0.7.1
    image.pullPolicy Image pull policy IfNotPresent
    rbacEnable If true, create & use RBAC resources true
    resources Pod resource requests & limits {}
    logLevel Global log level INFO
    agent.flexVolumeDirPath Path where the Rook agent discovers the flex volume plugins /usr/libexec/kubernetes/kubelet-plugins/volume/exec/
    agent.toleration Toleration for the agent pods
    agent.tolerationKey The specific key of the taint to tolerate
    mon.healthCheckInterval The frequency for the operator to check the mon health 45s
    mon.monOutTimeout The time to wait before failing over an unhealthy mon 300s

    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. For example, the following command will install rook where RBAC is not enabled.

    $ helm install --name rook rook-alpha/rook --set rbacEnable=false

    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 --name rook rook-alpha/rook -f values.yaml

    Here are the sample settings to get you started.

      prefix: rook
      repository: rook/rook

      pullPolicy: IfNotPresent
