I’m using centos6.6 and centos7.0 machines. I had installed docker
package in both machines. I need to do up a container inside an image
using docker, regarding my need there is an option available and go
through the following url (https://blog.docker.com/2013/09/docker-can-now-run-within-docker/) and also i implemented the same in our machines.
I’m facing issue like
" cannot start container system error: mount point for cgroup not found ".
Regarding the issue, i found the soluation for that using the following link :-
And i tried that too, still facing an another issue
[root@9c0cf273440f /]# umount cgroup
umount: cgroup: must be superuser to umount
[root@9c0cf273440f /]# sudo service cgconfig start
Starting cgconfig service: Error: cannot mount cpuset to /cgroup/cpuset: Permission denied
/sbin/cgconfigparser; error loading /etc/cgconfig.conf: Cgroup mounting failed
Failed to parse /etc/cgconfig.conf or /etc/cgconfig.d [FAILED]
Please help me to solve my issues.
