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 4 Daniel Walsh 2019-01-02 21:48:01 UTC 
Since we are replacing Docker CLI with Podman, we are verifing all RFE to make sure they work with podman.

The current release should have support for this.
Comment 6 Joy Pu 2019-01-17 09:09:32 UTC 
Test with podman-0.12.1.2-2.git9551f6b.el7.x86_64 with following Dockerfile
# cat Dockerfile
FROM busybox
COPY hello /hello 
RUN cat /etc/hosts
CMD ["/hello"]


# podman build --format docker --add-host mytest:192.168.1.2 -t test .
STEP 1: FROM busybox
STEP 2: COPY hello /hello 
--> Using cache d8226e44a933e5d5db834961e7fcbd7e9a54fc75fe03105756a2601f6c003472

Comment 11 Daniel Walsh 2019-09-17 13:24:18 UTC 
Docker and Podman have totally different storages.  So you need to copy or push/pull images to a registry to make this work.
Note You need to log in before you can comment on or make changes to this bug.
