Description of problem:
docker exec -it somecontainer bash
SELinux is preventing /usr/bin/grep from 'getattr' accesses on the chr_file /dev/pts/2.

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

If cree que de manera predeterminada, grep debería permitir acceso getattr sobre  2 chr_file.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
permita el acceso momentáneamente executando:
# grep grep /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2015-09-25 14:44:27 UTC
yum -y update docker-selinux

Or 

yum -y reinstall docker-selinux

This should be in the docker-selinux package.
