You can choose any Kubernetes install of your choice. The test framework only depends on
kubectl being configured. To install
kubectl, please see the official guide.
The developers of Rook are working on Minikube and thus it is the recommended way to quickly get Rook up and running. Minikube should not be used for production but the Rook authors consider it great for development. While other tools such as k3d/kind are great, users have faced issues deploying Rook.
Always use a virtual machine when testing Rook. Never use your host system where local devices may mistakenly be consumed.
To install Minikube follow the official guide. It is recommended to use the kvm2 driver when running on a Linux machine and the hyperkit driver when running on a MacOS. Both allow to create and attach additional disks to the virtual machine. This is required for the Ceph OSD to consume one drive. We don't recommend any other drivers for Rook. You will need a Minikube version 1.23 or higher.
Starting the cluster on Minikube is as simple as running:
It is recommended to install a Docker client on your host system too. Depending on your operating system follow the official guide.
Stopping the cluster and destroying the Minikube virtual machine can be done with:
Use helm.sh to install Helm and set up Rook charts defined under
_output/charts (generated by build):
- To install and set up Helm charts for Rook run
- To clean up
These helper scripts depend on some artifacts under the
_output/ directory generated during build time. These scripts should be run from the project root.
If Helm is not available in your
PATH, Helm will be downloaded to a temporary directory (
/tmp/rook-tests-scripts-helm) and used from that directory.
Using local Rook image on minikube cluster¶
Developers can test quickly their changes by building and using the local Rook image on their minikube cluster.
1) Set the local Docker environment to use minikube:
2) Build your local Rook image. The following command will generate a Rook image labeled in the format
3) Tag the generated image as
rook/ceph:master so operator will pick it.
4) Create a Rook cluster in minikube, or if the Rook cluster is already configured, apply the new operator image by restarting the operator.
