Bug 1822640

Description of problem:
Following the steps to install ceph with the cockpit on RHEL 8.1 https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/4/html-single/installation_guide/index#install-and-configure-the-cockpit-ceph-installer_install
After a successful log in, running "sudo ansible-runner-service.sh -s" at step 3.3 fails to pull rhceph/ansible-runner-rhel8 because this container is only available on registry.redhat.io but this registry is not in the search list by default.


Version-Release number of selected component (if applicable):
Ceph4 on RHEL8.1 using Cockpit


How reproducible:
Follow https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/4/html-single/installation_guide/index to prepare an installation with the cockpit.


Actual results:
The script ansible-runner-service.sh at step 3.3 fails to pull a container

Failed to fetch the container. Unable to continue



Expected results:
The script should be able to pull the container.


Additional info:
registry.redhat.io is missing in /etc/containers/registries.conf on RHEL 8.1. This is the default list on RHEL 8.1:
[registries.search]
registries = ['registry.access.redhat.com', 'registry.fedoraproject.org', 'registry.centos.org', 'docker.io']

It should be
[registries.search]
registries = ['registry.redhat.io', 'registry.access.redhat.com', 'registry.fedoraproject.org', 'registry.centos.org', 'docker.io']
