# If docker_options are provided we should fail. We should not install docker and ignore
# the users configuration. NOTE: docker_options == inventory:openshift_docker_options

msg: |
Docker via System Container does not allow for the use of the openshift_docker_options
variable. If you want to use openshift_docker_options you will need to use the
traditional docker package install. Otherwise, comment out openshift_docker_options
in your inventory file.
