The documentation instructs users to install upstream unsupported docker, if users perform this, their container runtime is not supported by Red Hat technical support:

https://access.redhat.com/documentation/en-us/red_hat_process_automation_manager/7.13/html/deploying_red_hat_process_automation_manager_on_red_hat_openshift_container_platform/dm-openshift-prepare-con_openshift-operator#externaldb-build-proc_openshift-operator

Installing upstream docker violates the Container Support Policy located here: https://access.redhat.com/articles/2726611

It also instructs users to install upstream CEKit. 

A customer opened a support case reporting this on the version 8.0 docs, so I also would like instruction on where to report a this Docs bug on the version 8.0 as well:
