NAME

   cgmanager - a daemon to manage cgroups

SYNOPSIS

   cgmanager [OPTION]...

DESCRIPTION

   cgmanager  is  a daemon to manage cgroups.  Programs and users can make
   D-Bus requests to administer cgroups over which  they  have  privilege.
   To  ensure  that  users  may not exceed their privilege in manipulating
   cgroups, the cgroup manager accepts regular D-Bus  requests  only  from
   tasks  within  its  own  process-id  and user namespaces.  For tasks in
   private namespaces (such as containers), SCM-enhanced D-Bus  calls  are
   available.   Using  these  manually  is  not recommended.  Rather, each
   container is advised to run a cgproxy, which will forward  plain  D-Bus
   requests as SCM-enhanced D-Bus requests to the host cgmanager.

EXAMPLES

   To create a new memory cgroup called 'compute', you can use:
   dbus-send                                                 --print-reply
   --address=unix:path=/sys/fs/cgroup/cgmanager/sock    --type=method_call
   /org/linuxcontainers/cgmanager  org.linuxcontainers.cgmanager0_0.Create
   string:'memory' string:"compute" > /dev/null 2>&1
   To set a limit of 100000,
   dbus-send                                                 --print-reply
   --address=unix:path=/sys/fs/cgroup/cgmanager/sock    --type=method_call
   /org/linuxcontainers/cgmanager
   org.linuxcontainers.cgmanager0_0.SetValue               string:'memory'
   string:"compute" string:memory.limit_in_bytes int32:100000 >  /dev/null
   2>&1
