Rhel7 atomic docker base image subscription

Question

I'm trying to test out the RHEL 'minimal' atomic base images. However I can see no way to install packages on them.

If I try 'microdnf update' I get this:

bash-4.2# microdnf update
(process:10): librhsm-WARNING **: Found 0 entitlement certificates
(process:10): librhsm-WARNING **: Found 0 entitlement certificates
Nothing to do.

Subscription manager doesn't seem to exist:

bash-4.2# subscription-manager
bash: subscription-manager: command not found

How do i provide subscription to this?

httpd for testing, but the basic "update" isn't working at all. — karthik101, Dec 06 '17 at 08:00
Any ideas on how to provide host subscription to the container? — karthik101, Dec 06 '17 at 19:57

Seems that the atomic container inherits the subscription from the host, as explained in a comment here: https://access.redhat.com/discussions/3219221

I've tested running microdnf in the container on a RHEL host without subscriptions attached and I get:

(process:5): librhsm-WARNING **: Found 0 entitlement certificates

After registering the host and attaching it a valid subscription, the atomic-rhel container does not return the warning anymore.
