Description of problem:

In RHOSP 16.2.5, the glance_api_cron container is created even though the image cache feature of glance is not enabled[1]

In that case, tripleo_glance_api_cron_healthcheck.service will fail if the Image cache of the glance is not enabled.[2]

It is assumed that this may be due to the fact that cron jobs are not created in the glance_api_cron container if the glance image cache is not enabled.[3]

How reproducible:

This always happens when Image cache is disabled in RHOSP16.2.5

Actual results:
tripleo_glance_api_cron_healthcheck.service fail

Expected results:
tripleo_glance_api_cron_healthcheck.service does not fail



Additional info:

found this bugzilla similar to the error,

https://bugzilla.redhat.com/show_bug.cgi?id=2159566 

but the bugzilla is for RHOSP version 16.2.4 and the resolution is to upgrade to 16.2.5

The solution cannot be applied here as the customer environment is already 16.2.5
