Well, atomic scan works well on my RHEL7 system when I ran atomic install and run w/ rhel7/openscap image firstly.

Alex, I hard-coded the version of the openscap container that I was told to use in my config file.  I believe that is the only change from the defaults:

# cat /etc/atomic.d/openscap 
type: scanner
scanner_name: openscap
image_name: brew-pulp-docker01.web.prod.ext.phx2.redhat.com:8888/rhel7/openscap:7.2-7
default_scan: cve
custom_args: ['-v', '/etc/oscapd:/etc/oscapd:ro']
scans: [ 
      { name: cve,
        args: ['oscapd-evaluate', 'scan',  '--no-standard-compliance', '--targets', 'chroots-in-dir:///scanin',  '--output', '/scanout'],
        description: "Performs a CVE scan based on known CVE data"},
      { name: standards_compliance,
        args: ['oscapd-evaluate', 'scan', '--targets', 'chroots-in-dir:///scanin',  '--output', '/scanout', '--no-cve-scan'],
        description: "Performs a standard scan"
      }
]

Micah, it should be not important difference, but it's strange, I have never got a succeed on my rhelah 7.2.5 w/ latest atomic installed by development mode(ostree admin unlock).

This looks like an selinux issue to me. The devicemapper error messages aside, the scan worked for me on atomic host in permissive mode

Lokesh, yeah, I also fund SELinux issue, please see https://bugzilla.redhat.com/show_bug.cgi?id=1311544#c13, but unfortunately, there is nothing complains by journalctl -f | grep -iE 'AVC'.

Alex.  Try 

ausearch -m avc -ts recent 
After failure.

Dan see below steps. fwiw, ausearch wasn't available on atomic host, so I manually installed it from brew. Are there any additional steps to do before ausearch to make sure it's working properly?

Brent, if we hack Atomic Host w/ development or hotfix mode, and SELinux is enforcing on Atomic Host, yes, it's the same issue. 

If I change SELinux to Permissive mode then everything is okay, as Daniel mentioned in bug 1311544, SELinux will not work with unlock/overlayfs, it should be a root reason.

Atomic scanner works on rhelah 7.2.5(c6530479e2), but I still can encounter the same issue in Comment 0.

Ok so this should probably be renamed to docker and SELinux and Overlayfs do not work together.  Running docker on an overlayfs system is going to cause issues

The issue should been fixed on RHELAH 7.2.5 (9bfe1fb650), I haven't seen issues again like Comment 0.

Daniel, for now, I saw different result from Comment 15 between atomic-1.10.5-5.el7.x86_64 and atomic-1.10.5-7.el7.x86_64.

Well, I can't see issues in Description on atomic-1.10.5-7, so moving the bug to VERIFIED status, for other question, I will file a separated bug.

Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.
