Managing the Compliance Operator

This section describes the lifecycle of security content, including how to use an updated version of compliance content and how to create a custom ProfileBundle object.

ProfileBundle CR example

The ProfileBundle object requires two pieces of information: the URL of a container image that contains the contentImage and the file that contains the compliance content. The contentFile parameter is relative to the root of the file system. You can define the built-in rhcos4 ProfileBundle object as shown in the following example:

apiVersion: compliance.openshift.io/v1alpha1
kind: ProfileBundle
metadata:
  creationTimestamp: "2022-10-19T12:06:30Z"
  finalizers:
  - profilebundle.finalizers.compliance.openshift.io
  generation: 1
  name: rhcos4
  namespace: openshift-compliance
  resourceVersion: "46741"
  uid: 22350850-af4a-4f5c-9a42-5e7b68b82d7d
spec:
  contentFile: ssg-rhcos4-ds.xml (1)
  contentImage: registry.redhat.io/compliance/openshift-compliance-content-rhel8@sha256:900e... (2)
status:
  conditions:
  - lastTransitionTime: "2022-10-19T12:07:51Z"
    message: Profile bundle successfully parsed
    reason: Valid
    status: "True"
    type: Ready
  dataStreamStatus: VALID
1 Location of the file containing the compliance content.
2 Content image location.

The base image used for the content images must include coreutils.

Updating security content

Security content is included as container images that the ProfileBundle objects refer to. To accurately track updates to ProfileBundles and the custom resources parsed from the bundles such as rules or profiles, identify the container image with the compliance content using a digest instead of a tag:

$ oc -n openshift-compliance get profilebundles rhcos4 -oyaml
Example output
apiVersion: compliance.openshift.io/v1alpha1
kind: ProfileBundle
metadata:
  creationTimestamp: "2022-10-19T12:06:30Z"
  finalizers:
  - profilebundle.finalizers.compliance.openshift.io
  generation: 1
  name: rhcos4
  namespace: openshift-compliance
  resourceVersion: "46741"
  uid: 22350850-af4a-4f5c-9a42-5e7b68b82d7d
spec:
  contentFile: ssg-rhcos4-ds.xml
  contentImage: registry.redhat.io/compliance/openshift-compliance-content-rhel8@sha256:900e... (1)
status:
  conditions:
  - lastTransitionTime: "2022-10-19T12:07:51Z"
    message: Profile bundle successfully parsed
    reason: Valid
    status: "True"
    type: Ready
  dataStreamStatus: VALID
1 Security container image.

Each ProfileBundle is backed by a deployment. When the Compliance Operator detects that the container image digest has changed, the deployment is updated to reflect the change and parse the content again. Using the digest instead of a tag ensures that you use a stable and predictable set of profiles.
