How to run interactive Centos 6 within docker

I'm unable to run an interactive session with Centos:6 in docker. Works perfectly with Centos:7

>docker -v
Docker version 18.03.0-ce, build 0520e24302
>docker pull centos:6
...
>docker run -it centos:6
[just returns to my terminal]

>docker pull centos:7
...
>docker run -it centos:7
>[root@f8c0430ed2ba /]#cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)
Any idea what is going on ?

I tried with older version of docker and i pulled all new images Centos:6/6.6/6.7/6.8/6.9 and it shows the same problems. I also tried with /bin/bash or sh at the end.

Also i'm sure that it used to work more or less one year ago. I'm using ArchLinux
