تثبيت (إعادة التثبيت) Discourse باستخدام Docker على CentOS 7

[elijah (Eli the Bearded)]

People have gotten devicemapper to work, at least mostly work, but it is not a recommended storage driver and I gather you’ll get mysterious errors.

New installation on Fedora 23 - FAILED RuntimeError: cd /var/www/discourse && su discourse -c

Devicemapper is non starter, fails spectacularly under load and causes corruption. We block setup if we detect devicemapper. You need aufs or another better supported docker filesystem.
