Developer Environment

Install Kubernetes

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.

Minikube

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:

1
2
3
4
5
# On Linux
minikube start --disk-size=40g --extra-disks=1 --driver kvm2

# On MacOS
minikube start --disk-size=40g --extra-disks=1 --driver hyperkit

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:

minikube delete

Install Helm

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 tests/scripts/helm.sh up.
  • To clean up tests/scripts/helm.sh clean.

Note

These helper scripts depend on some artifacts under the _output/ directory generated during build time. These scripts should be run from the project root.

Note

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.
