Comment 2 Micah Abbott 2016-08-15 13:28:40 UTC
This looks like it is fixed in the master branch upstream:

# git rev-parse HEAD
# docker images | grep rhel6
# ./atomic scan --list
Scanner: atomic_scan_openscap 
  Image Name:
     Scan type: cve * 
     Description: Performs a CVE scan based on known CVE data

* denotes defaults
# ./atomic scan
Unable to associate '' with an image or container

Comment 3 Daniel Walsh 2016-08-26 16:08:41 UTC
With atomic-1.12.0-devel I am seeing the following.

# atomic scan --scanner openscap --scan_type cve
Unable to associate '' with an image or container

Fixed in atomic-1.12

Comment 5 Alex Jia 2016-09-18 06:08:25 UTC
Moving to VERIFIED status per Comment 3 and following testing.

# rpm -q atomic

# atomic scan --scanner openscap --scan_type cve
Unable to associate '' with an image or container
