## CIS Kubernetes Benchmark support
|
||||
|

kube-bench supports the tests for multiple versions of Kubernetes (1.6, 1.7, 1.8, and 1.11) as defined in the CIS Benchmarks 1.0.0, 1.1.0, 1.2.0, and 1.3.0 respectively. It will determine the test set to run based on the Kubernetes version running on the machine.

kube-bench supports the tests for Kubernetes as defined in the CIS Benchmarks 1.0.0 to 1.4.0 respectively.

By default kube-bench will determine the test set to run based on the Kubernetes version running on the machine.

There is also preliminary support for Red Hat's Openshift Hardening Guide for 3.10 and 3.11. Please note that kube-bench does not automatically detect Openshift - see below.

### Running in a kubernetes cluster
|
||||
|
||||
You can run kube-bench inside a pod, but it will need access to the host's PID namespace in order to check the running processes, as well as access to some directories on the host where config files and other files are stored.
|
||||
|
||||
Master nodes are automatically detected by kube-bench and will run master checks when possible.
|
||||
The detection is done by verifying that mandatory components for master are running. (see [config file](#configuration).

## 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.

- [PASS] and [FAIL] indicate that a test was run successfully, and it either passed or failed

- [WARN] means this test needs further attention, for example it is a test that needs to be run manually

### Omitting checks
|
||||
|
||||
If you decide that a recommendation is not appropriate for your environment, you can choose to omit it by editing the test YAML file to give it the check type `skip` as in this example:
