The following parameters can be specified to setup the controller:

* **`shares`** *(uint64, OPTIONAL)* - specifies a relative share of CPU time available to the tasks in a cgroup
* **`shares`** *(uint64, OPTIONAL)* - specifies a relative share of CPU time available to the tasks in a cgroup.

* **`quota`** *(uint64, OPTIONAL)* - specifies the total amount of time in microseconds for which all tasks in a cgroup can run during one period (as defined by **`period`** below)
* **`quota`** *(uint64, OPTIONAL)* - specifies the total amount of time in microseconds for which all tasks in a cgroup can run during one period (as defined by **`period`** below).

* **`period`** *(uint64, OPTIONAL)* - specifies a period of time in microseconds for how regularly a cgroup's access to CPU resources should be reallocated (CFS scheduler only)
* **`period`** *(uint64, OPTIONAL)* - specifies a period of time in microseconds for how regularly a cgroup's access to CPU resources should be reallocated (CFS scheduler only).

* **`realtimeRuntime`** *(uint64, OPTIONAL)* - specifies a period of time in microseconds for the longest continuous period in which the tasks in a cgroup have access to CPU resources
* **`rtRuntime`** *(uint64, OPTIONAL)* - specifies a period of time in microseconds for the longest continuous period in which the tasks in a cgroup have access to CPU resources, it applies to realtime (RT) scheduler only).

* **`realtimePeriod`** *(uint64, OPTIONAL)* - same as **`period`** but applies to realtime scheduler only
* **`rtPeriod`** *(uint64, OPTIONAL)* - same as **`period`** but applies to realtime (RT) scheduler only.

* **`cpus`** *(string, OPTIONAL)* - list of CPUs the container will run in
* **`cpus`** *(string, OPTIONAL)* - list of CPUs the container will run in.

* **`mems`** *(string, OPTIONAL)* - list of Memory Nodes the container will run in
* **`mems`** *(string, OPTIONAL)* - list of Memory Nodes the container will run in.
