### Running in an EKS cluster
There is a `job-eks.yaml` file for running the kube-bench node checks on an EKS cluster. **Note that you must update the image reference in `job-eks.yaml`.** Typically you will push the container image for kube-bench to ECR and refer to it there in the YAML file.
There are two significant differences on EKS:
* It uses [config files in JSON format](https://kubernetes.io/docs/tasks/administer-cluster/kubelet-config-file/)
* It's not possible to schedule jobs onto the master node, so master checks can't be performed

## Running on OpenShift
kube-bench includes a set of test files for Red Hat's OpenShift hardening guide for OCP 3.10 and 3.11. To run this you will need to specify `--version ocp-3.10` when you run the `kube-bench` command (either directly or through YAML). This config version is valid for OCP 3.10 and 3.11.
