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 Ondřej Budai 2021-02-23 08:29:06 UTC 
/etc/containers/registries.conf.d/rhel-shortnames.conf shipped in containers-common-1:1.2.2-1.module+el8.4.0+10073+30e5ea69 (subpackage of skopeo) has a wrong shortname for ubi8-minimal:

"ubi8-minimal" = "registry.access.redhat.com/repository/ubi8-minimal"


When I try to pull the image using the short name, it fails:

$ podman pull ubi8-minimal
Resolved "ubi8-minimal" as an alias (/etc/containers/registries.conf.d/rhel-shortnames.conf)
Trying to pull registry.access.redhat.com/repository/ubi8-minimal:latest...
  name unknown: Repo not found
Error: Error initializing source docker://registry.access.redhat.com/repository/ubi8-minimal:latest: Error reading manifest latest in registry.access.redhat.com/repository/ubi8-minimal: name unknown: Repo not found


When I try to pull the image using the full name, it also fails:

$ podman pull registry.access.redhat.com/repository/ubi8-minimal
Trying to pull registry.access.redhat.com/repository/ubi8-minimal:latest...
  name unknown: Repo not found
Error: Error initializing source docker://registry.access.redhat.com/repository/ubi8-minimal:latest: Error reading manifest latest in registry.access.redhat.com/repository/ubi8-minimal: name unknown: Repo not found


The official docs (https://catalog.redhat.com/software/containers/ubi8/ubi-minimal/5c359a62bed8bd75a2c3fba8?gti-tabs=unauthenticated&container-tabs=gti) says that ubi8-minimal is available at the following address:

registry.access.redhat.com/ubi8/ubi-minimal

I tried `podman pull registry.access.redhat.com/ubi8/ubi-minimal` and it indeed worked.

Interestingly, Fedora uses `registry.access.redhat.com/ubi8-minimal` as a shortname and it also works.
Comment 4 Tom Sweeney 2021-02-23 20:03:18 UTC 
Ondřej,

You should not need to do this, but as a test, can you change the entry in /etc/containers/registries.conf.d/rhel-shortnames.conf of:

"ubi8-minimal" = "registry.access.redhat.com/repository/ubi8-minimal"

to

"ubi8-minimal" = "registry.access.redhat.com/ubi8/ubi-minimal"

and see if you can pull with the short name?

Scott McCarty, can you please confirm that the "registry.access.redhat.com/ubi8/ubi-minimal" is the correct location we should have in the conf file for RHEL 8.4?

Assigning to Valentin for the moment, but this may be heading to Jindrich quickly.
Comment 5 Ondřej Budai 2021-02-23 20:10:14 UTC 
Yes, this fix works.
Comment 6 Valentin Rothberg 2021-02-24 10:39:27 UTC 
Looking at https://github.com/containers/shortnames/blob/main/shortnames.conf, we have:

  "ubi8-minimal" = "registry.access.redhat.com/ubi8-minimal"
  "ubi8/ubi-minimal" = "registry.access.redhat.com/ubi8-minimal"

This must be resolved on the packaging side, so I am assigning it to Jindrich.
Comment 7 Jindrich Novy 2021-02-24 11:04:39 UTC 
The script using Pyxis API to generate rhel-shornames.conf needs to be changed to get this one fixed. Work is in progress.
Comment 8 Jindrich Novy 2021-02-24 14:10:58 UTC 
Can you please re-test with the floowing scratch build?

Comment 14 Ondřej Budai 2021-02-25 07:55:32 UTC 
The scratch build fixed the issue.

Thanks Ondřej. Now I will allow PM to review rhel-shortnames.conf which is attached to this bug. Once confirmed I will commit and build.

Laurie, can you please confirm the attached rhel-shortnames.conf looks good?
Comment 18 Tom Sweeney 2021-02-26 00:47:12 UTC 
I'm not Laurie, but I've perused through the rhel-shortnames.conf and tried pulling each of the ubi-minimal images and they all LGTM.  Jindrich, do you by chance have a change log/diff between this file that you've attached and the one that you started with?  Just to quadruple check.
