Resposta de erro do daemon: o driver falhou ao programar a conectividade externa no nó de extremidade reverent_newton (HASH)

Question

Meu ambiente:

# cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 7.3 (Maipo)
# docker --version
Docker version 1.12.3, build 9858ec7
# 

Sempre que eu tento executar o contêiner usando -p flag, acabo com o seguinte erro:

# docker run -p 8080:80 -d drupal
