The Compliance Operator lets OKD administrators describe the required compliance state of a cluster and provides them with an overview of gaps and ways to remediate them. The Compliance Operator assesses compliance of both the Kubernetes API resources of OKD, as well as the nodes running the cluster. The Compliance Operator uses OpenSCAP, a NIST-certified tool, to scan and enforce security policies provided by the content.

The Compliance Operator is available for Fedora CoreOS (FCOS) deployments only.

Compliance Operator profiles

There are several profiles available as part of the Compliance Operator installation. You can use the oc get command to view available profiles, profile details, and specific rules.

  • View the available profiles:

    $ oc get -n openshift-compliance profiles.compliance
    Example output
    NAME                 AGE
    ocp4-cis             94m
    ocp4-cis-node        94m
    ocp4-e8              94m
    ocp4-high            94m
    ocp4-high-node       94m
    ocp4-moderate        94m
    ocp4-moderate-node   94m
    ocp4-nerc-cip        94m
    ocp4-nerc-cip-node   94m
    ocp4-pci-dss         94m
    ocp4-pci-dss-node    94m
    rhcos4-e8            94m
    rhcos4-high          94m
    rhcos4-moderate      94m
    rhcos4-nerc-cip      94m

    These profiles represent different compliance benchmarks. Each profile has the product name that it applies to added as a prefix to the profile’s name. ocp4-e8 applies the Essential 8 benchmark to the OKD product, while rhcos4-e8 applies the Essential 8 benchmark to the Fedora CoreOS (FCOS) product.

  • Run the following command to view the details of the rhcos4-e8 profile:

    $ oc get -n openshift-compliance -oyaml profiles.compliance rhcos4-e8
    Example output
    apiVersion: compliance.openshift.io/v1alpha1
