- There are some exceptions to note when doing the idempotency in this module.
- The strategy is to use the oc adm router command to generate a default
- configuration when creating or updating a router.  Often times there
- differences from the generated template and what is in memory in openshift.
- We make exceptions to not check these specific values when comparing objects.
- Here are a list of exceptions:
- - DeploymentConfig:
    - dnsPolicy
    - terminationGracePeriodSeconds
    - restartPolicy
    - timeoutSeconds
    - livenessProbe
    - readinessProbe
    - terminationMessagePath
    - hostPort
    - defaultMode
  - Service:
    - portalIP
    - clusterIP
    - sessionAffinity
    - type
  - ServiceAccount:
