subscription-manager currently detects whether it is running in a container, and disables itself in that case. This is because the business requirements so far are that RHEL containers get the entitlements from the host. Over the years, more use cases showed up (e.g. UBI running in OCP 4, UBI running on non-RHEL hosts, etc) that are valid for us and for our customers, and they are not easy to get with the current detection in subscription-manager. Hence, as result of internal discussions, we decided to relax/tweak the existing detection; this will mean the following changes: - the detection done for secrets will be improved to also check that /etc/pki/entitlement-host exists and it contains entitlement certificates; this way, an empty /etc/rhsm-host will not trigger the container mode anymore Updates to documentations/KBs/etc will be done separately after this is implemented, and not tracked by this bz. Related: bug 2203096 (this is a backport of only the changes relevant in RHEL 8).
