Docker on CentOS 6: FAIL

Intro
I think I’ve been running CentOS 6 for six years now. With upgrades I’m at v 6.9. It was nice and new six years ago, but not so much anymore. I think it showed its age when I tried to run Docker. It just wouldn’t fly an I don’t feel like debugging it. The conventional wisdom seems to be that it is not possible – the two are incompatible, which further discouraged me.

Here are my notes

followed https://www.liquidweb.com/kb/how-to-install-docker-on-centos-6/ - DrJ 6/18/18
 
my problem:
level=error msg="[graphdriver] prior storage driver \"devicemapper\" failed: Error running DeviceCreate (CreatePool) dm_tas
k_run failed"

trying:
 
yum install --setopt=obsoletes=0 \

   docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch

Conclusion
running docker on CentOS v 6.9 in 2018 may be impossible or so difficult as to be practically impossible. i give up.
