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.

Red Hat Product Errata RHBA-2016:2643 0 normal SHIPPED_LIVE Red Hat Enterprise Linux Atomic Tools 7.3 Container Image Update 2016-11-03 21:52:32 UTC

Description Marius Vollmer 2016-01-19 09:43:23 UTC 
Description of problem:

Contrary to the documentation (https://access.redhat.com/documentation/en/red-hat-enterprise-linux-atomic-host/version-7/getting-started-with-containers/#using_the_atomic_tools_container_image), running sosreport inside the rhel-tools container seems to collect information from the container, and not from the host.

For example, the /etc/os-release file in the report archive is a copy of /etc/os-relase from inside the container, and not of /host/etc/os-release.

Version-Release number of selected component (if applicable):
Image has tag "latest" *cough* and id is fd2acbeb2b97, if that helps.
sos-3.2-35.el7.noarch

How reproducible:
Always

Steps to Reproduce:
1. atomic run rhel7/rhel-tools
2. # sosreport
3. # tar -xOaf sosreport-localhost.localdomain.localdomain-20160119092307.tar.xz sosreport-localhost.localdomain.localdomain-20160119092307/etc/os-release

Actual results:
Contents of /etc/os-release is shown

Expected results:
Contents of /host/etc/os-release is shown


Additional info:
This can be fixed by using --sysroot /host, but the docs seem to say that this isn't necessary.

> This can be fixed by using --sysroot /host, but the docs seem to say that this

Right; we have a whole separate policy for Atomic (i.e. it is treated as a separate distro just like Fedora/Ubuntu/whatever). One of the things the policy should do is to detect we are running with HOST and retrieve the path from the environment.

Out of curiousity, what do you get in the boilerplate text? This should also be customized for Atomic:

"""\
This command will collect diagnostic and configuration \
information from this Red Hat Atomic Host system.

An archive containing the collected information will be \
generated in /host/var/tmp and may be provided to a Red Hat \
support representative.

Any information provided to %(vendor)s will be treated in \
accordance with the published support policies at:

    https://access.redhat.com/

The generated archive may contain data considered sensitive \
and its content should be reviewed by the originating \
organization before being passed to any third party.
%(vendor_text)s
"""

The policy retrieves HOST from the environment and then inspects $HOST/etc/redhat-release to detect if we are running in an Atomic environment.
Comment 4 Bryn M. Reeves 2016-01-19 16:37:01 UTC 
fwiw I think this is almost certainly the same as bug 1299578. We do some extra cosmetic tweaks on Atomic vs. the sos-in-container case for RHEL but only really to print the custom boilerplate text.

Current sos releases should support running in a privileged container on any capable distribution.

Since you mention that it works correctly with --sysroot we can rule out that the sos version in the image has been updated to some pre-7.2 version that was missing the sysroot support.

We'll need access to an environment for testing or detailed logs to make progress with this.

Thus, $HOST is set, the banner talks about Atomic Host, but it still writes into /var/tmp.

Fix for bug 1299578 will address the last part as well (IIUC).

> Fix for bug 1299578 will address the last part as well (IIUC).

Correct: the paths in the banner message, final message, and the actual path used are all manifestations of the same bug - that due to the missing "container_uuid" that these versions check for sos thinks it is running in a non-container environment and does not evaluate the HOST environment variable.

Let me know if it would be helpful to have a build with this patch included for testing.
Comment 9 Bryn M. Reeves 2016-01-21 11:15:27 UTC 
btw you could also work around this for testing purposed by adding '-e container_uuid=anything' to the 'docker run' command (sos does not inspect the content of the variable).

Not for us, but I am happy to help with verifying the fix.
