Description of problem:

Overcloud deployment with TLS everywhere fails due to controller nodes not being able to pull 192.168.24.1:8787/rhosp15/openstack-redis:pcmklatest:

Checking /var/log/tripleo-container-image-prepare.log we can see that the openstack-redis image was uploaded with a specific tag:

[root@undercloud-0 stack]# grep redis /var/log/tripleo-container-image-prepare.log
