Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:

When pulling an image from the Red Hat container registry that requires a subscription, docker returns with error "unknown: Not Found".

Version-Release number of selected component (if applicable):
docker 1.10.3-57.el7.x86_64

How reproducible:
always

Steps to Reproduce:
1. given an unsubscribed host, docker pull registry.access.redhat.com/rhmap4/mongodb

Actual results:
Trying to pull repository registry.access.redhat.com/rhmap4/mongodb ...
unknown: Not Found

Expected results:
Trying to pull repository registry.access.redhat.com/rhmap4/mongodb ...
Image requires a valid subscription. Refer to product documentation.

isn't this a Registry issue? a RH registry issue. There should be a more appropriate error from the registry itself to be shown to user. I'm not sure if docker could even understand that "Not Found" as "no valid subscription"

Good point. It may be a registry issue. Returning a 401 or maybe even a custom 4xx code--something useful.
