-------------------------------------------

             Summary: Docker as containerizer option value fails
                 Key: MESOS-2509
                 URL: https://issues.apache.org/jira/browse/MESOS-2509
             Project: Mesos
          Issue Type: Bug
          Components: containerization, docker, slave
    Affects Versions: 0.21.1
         Environment: Operating system: Ubuntu 14.04.1 LTS
Kernel: GNU/Linux 3.13.0-44-generic x86_64
Hardware: AWS's EC2 t2.small instances

            Reporter: Mickael van der Beek
            Priority: Minor


When running the following command:

{code:shell}
sudo /usr/sbin/mesos-slave --master=zk://MASTER_IP:2181/mesos --log_dir=/var/log/mesos --hostname=SLAVE_IP --ip=SLAVE_IP
{code}

everything works and I have no issues but when specifying "docker" as containerizer, like this:

{code:shell}
sudo /usr/sbin/mesos-slave --master=zk://MASTER_IP:2181/mesos --log_dir=/var/log/mesos --hostname=SLAVE_IP --ip=SLAVE_IP --containerizers=docker
{code}

I get the following error:

{code:text}

Failed to create a containerizer: Could not create DockerContainerizer: Failed to find a mounted cgroups hierarchy for the 'cpu' subsystem; you probably need to mount cgroups manually!
{code}

The command:

{code:shell}
cat /proc/cgroups
{code}

returns:

{code:text}
#subsys_name	hierarchy	num_cgroups	enabled
cpuset	0	1	1
cpu	0	1	1
cpuacct	0	1	1

hugetlb	0	1	1
{code}

and the command:

{code:shell}
cat /proc/mounts
{code}

returns:
