Re: error during S2I build

Fri, 24 Mar 2017 10:37:01 -0700 

Still struggling with this.
cgroups was not started by default, so I started it, but still get the problem: 


error: failed to retrieve cgroup limits: cannot determine cgroup limits: 
open /sys/fs/cgroup/cpu/cpu.cfs_quota_us: no such file or directory


On the host machine that directory contains this:

$ ls /sys/fs/cgroup/cpu/

cgroup.clone_children  cgroup.sane_behavior  cpuacct.usage 
cpu.shares         release_agent  tasks
cgroup.procs           cpuacct.stat          cpuacct.usage_percpu 
notify_on_release  system.slice   user.slice


So, no cpu.cfs_quota_us.
What needs to be done?

    OK, sounds plausible, but not clear to me what the solution is.
    Cgroups need be enabled on centos? How?


​https://www.digitalocean.com/community/tutorials/how-to-limit-resources-using-cgroups-on-centos-6

I can't find similar docs for centos7, not sure if it's the same or not.

    Sounds like you do not have cgroups enabled, this is a known
    issue reported here:

        No, I'm running on Centos.

        Running that command didn't help - same error.

            I created a new Openshift setup running on a Centos 7.2
            machine. Installed docker and set to use
            --insecure-registry option.

            I started the cluster with `oc cluster up`. All OK.

            I can deploy a Docker image and access it fine.

            But when I try to do a S2I build (Python) the build
            fails with this error:

            error: failed to retrieve cgroup limits: cannot
            determine cgroup limits: open
            /sys/fs/cgroup/cpu/cpu.cfs_quota_us: no such file or
            directory

            What is needed to fix this?


        ​are you on fedora25? if so, a dnf update should solve it
        for you.

        alternatively you can run "setsebool -P
        container_manage_cgroup 1"

        ​


            Thanks
