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.

Comment 1 Matus Marhefka 2021-01-12 14:58:06 UTC
Will you be able to fix this in 8.4? Our oscap-podman depends on the join Go template so if you are not able to fix it on your side we will need to workaround. Please let us know.

Comment 2 Daniel Walsh 2021-01-12 15:38:27 UTC
Jon this looks like something you need to handle.

Comment 5 Jhon Honce 2021-01-29 21:12:18 UTC
c/common updated with https://github.com/containers/common/pull/426
podman will need to vendor in this update.

Comment 7 Jhon Honce 2021-02-02 16:28:34 UTC
https://github.com/containers/common/pull/426 provided changes to code
https://github.com/containers/podman/pull/9196 should have included fix in podman

Comment 8 Jindrich Novy 2021-02-05 15:29:06 UTC
Jhon, do you plan to fix it for 8.4.0 (podman-3.0)?

Comment 10 Jhon Honce 2021-02-10 16:11:31 UTC
https://github.com/containers/podman/pull/9285 fixes this issue for podman 3.0.0

Comment 16 Joy Pu 2021-02-22 07:18:01 UTC
Test with podman-3.0.1-1.module+el8.4.0+10073+30e5ea69.x86_64 and it works as expected. So set this to verified.
