Ceph Operator |

true |
{% include_relative branch.liquid %}
Installs rook to create, configure, and manage Ceph clusters on Kubernetes.
This chart bootstraps a rook-ceph-operator deployment on a Kubernetes cluster using the Helm package manager.
- Kubernetes 1.13+
- Helm 3.x
See the Helm support matrix for more details.
The Ceph Operator helm chart will install the basic components necessary to create a storage platform for your Kubernetes cluster.
- Install the Helm chart
- 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.
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
helm install --create-namespace --namespace rook-ceph rook-ceph rook-release/rook-cephTo deploy from a local build from your development environment:
- Build the Rook docker image:
make - Copy the image to your K8s cluster, such as with the
docker savethen thedocker loadcommands - Install the helm chart:
cd deploy/charts/rook-ceph
helm install --create-namespace --namespace rook-ceph rook-ceph .To see the currently installed Rook chart:
helm ls --namespace rook-cephTo uninstall/delete the rook-ceph deployment:
helm delete --namespace rook-ceph rook-cephThe 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.
The following tables lists the configurable parameters of the rook-operator chart and their default values.

You can pass the settings with helm command line parameters. Specify each parameter using the
--set key=value[,key=value] argument to helm install.
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.yamlFor example settings, see [values.yaml](https://github.com/rook/rook/tree/{{ branchName }}/deploy/charts/rook-ceph/values.yaml)
