Same result in ansible-2.4.0.0-5.el7 & ansible-2.3.2.0-2.el7 I ran into an issue like this recently while writing up the 'add container provider' playbooks for openshift-management. Specifically, in my playbook it was not picking up variables I had defined in my inventory, just like you have.
I looked quickly at the playbook you referenced, playbooks/byo/openshift-checks/adhoc.yml and confirmed you ran into the same 'issue' as me. That is to say, inventory variables are not being picked up.
This is caused by the definition of the 'hosts' in the adhoc checks playbook:
> - name: OpenShift health checks
> hosts: localhost
> connection: local
When `hosts` is 'localhost' I found that ansible does not consider the provided '-i hosts' inventory file.
I do not know if historically Ansible used to read the inventory file, but I know that the present behavior is to ignore the inventory. I'm tagging Russell to check this out, too.
The play runs against localhost, and the code aborts because openshift_deployment_type is not defined for localhost. Defining it (or just deployment_type) in the [OSEv3:vars] subsection does not define it for localhost. You can set it for localhost explicitly by adding at the top of the inventory file: localhost openshift_deployment_type=openshift-enterprise ...or by specifying it as an extra variable. Obviously, you shouldn't have to do that to get this to list checks. Unrelated changes to initialization code broke this path. Merged to master 3.7 backport https://github.com/openshift/openshift-ansible/pull/6772 Verified with version openshift-ansible-3.7.26-1.git.0.f87f1af.el7, known health checks can be list with command [1].
[1]. ansible-playbook -i hosts -v /usr/share/ansible/openshift-ansible/playbooks/byo/openshift-checks/adhoc.yml

Message: This playbook is meant to run health checks, but no checks were requested. Set the `openshift_checks` variable to a comma-separated list of check names or a YAML list. Available checks:
curator
diagnostics
disk_availability
docker_image_availability
docker_storage
elasticsearch
etcd_imagedata_size
etcd_traffic
etcd_volume
fluentd
fluentd_config
kibana
logging
logging_index_time
memory_availability
ovs_version
package_availability
package_update
package_version
Tags can be used as a shortcut to select multiple checks. Available tags and the checks they select:
@etcd = etcd_imagedata_size,etcd_traffic,etcd_volume
@health = curator,diagnostics,docker_storage,elasticsearch,etcd_traffic,etcd_volume,fluentd,fluentd_config,kibana,logging_index_time,ovs_version
@logging = curator,elasticsearch,fluentd,kibana,logging_index_time
@preflight = disk_availability,docker_image_availability,docker_storage,memory_availability,package_availability,package_update,package_version
