Description M. Edward (Ed) Borasky 2014-11-02 22:52:56 UTC
Description of problem:
Running Docker - I'm in the 'docker' group. I typed 'docker top developerc'. It displayed the data but threw an SE Linux error (this bug).
SELinux is preventing ps from 'getattr' accesses on the directory /proc/<pid>.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that ps should be allowed getattr access on the <pid> directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep ps /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
