Section Number and Name:

Creating an RHCOS images cache (optional) - step 13

Describe the issue:

The podman command given, points to a container image in the `centos7` repository in quay.

~~~
$ podman run -d --name rhcos_image_cache \
-v /home/kni/rhcos_image_cache:/var/www/html \
-p 8080:8080/tcp \
quay.io/centos7/httpd-24-centos7:latest
~~~

Suggestions for improvement:

We should point the podman command to pull and run with a container image provided and maintened by Red Hat, i.e.:

registry.redhat.io/rhscl/httpd-24-rhel7:latest

~~~
$ podman run -d --name rhcos_image_cache \
-v /home/kni/rhcos_image_cache:/var/www/html \
-p 8080:8080/tcp \
registry.redhat.io/rhscl/httpd-24-rhel7:latest
~~~

Additional information:

This request is to avoid confusion on users while trying to understand if the centos7 container image is tested/supported by Red Hat.
