Cloud Foundry Container Runtime (CFCR) utilizes BOSH to deploy and manage your Kubernetes cluster.
A Kubernetes cluster can be deployed to your choice of IaaS. Please follow the guide here to install it on GCP, AWS, vSphere or OpenStack.
Set your kubectl to point your CLI to the deployed kubernetes cluster. See the instructions here for steps to access your cluster.
You can then run the k8s conformance test by running:
curl -L https://raw.githubusercontent.com/cncf/k8s-conformance/master/sonobuoy-conformance.yaml | kubectl apply -f -
