Intel Device Plugins Operator Application Overview
|
||||
==================================================
|
||||
|
||||
This application provides a set of plugins developed by Intel to facilitate the
|
||||
use of Intel hardware features in Kubernetes clusters. These plugins are
|
||||
designed to enable and optimize the use of Intel-specific hardware capabilities
|
||||
in a Kubernetes environment.
|
||||
|
||||
The following plugins are supported:
|
||||
|
||||
* Intel |QAT| device plugin 0.26.0
|
||||
|
||||
* Intel |GPU| device plugin 0.26.0
|
||||
|

|
||||
Install Intel Device Plugins Operator Application
|
||||
-------------------------------------------------
|
||||
|
||||
Intel device plugin Operator application is required to be installed for
|
||||
configuring the Intel |QAT| device plugin and the Intel |GPU| device plugin.
|
||||
Installation steps are mentioned in the respective device plugin configuration
|
||||
sections below.

Kubernetes QAT Device Plugin Configuration
|

==========================================
|

|
||||
Intel® QuickAssist Technology (Intel® QAT) accelerates cryptographic workloads
|
||||
by offloading the data to hardware capable of optimizing those functions. This
|
||||
guide describes how to enable and consume the Intel QAT device plugin in
|
||||
StarlingX.

|

:depth: 1
|
||||
|
||||
-------------
|
||||
Prerequisites
|
||||
-------------
|
||||
|
||||
- Install Intel QuickAssist device on host.
|
||||
- Install StarlingX on bare metal with DPDK enabled. Refer to the |_link-inst-book|
|
||||
for details.
|
||||
|
||||
------------------------------
|
||||
Enable Intel QAT device plugin
|
||||
------------------------------
|
||||
|
||||
The Intel QAT device plugin daemonset is pre-installed in StarlingX. This
|
||||
section describes the steps to enable the Intel QAT device plugin for
|
||||
discovering and advertising QAT VF resources to Kubernetes host.
|
||||
|
||||
#. Verify QuickAssist SR-IOV virtual functions are configured on a specified
|
||||
node after StarlingX is installed. This example uses the worker-0 node.
|
||||
|
||||
::
|
||||
|
||||
$ ssh worker-0
|
||||
$ for i in 0442 0443 37c9 19e3; do lspci -d 8086:$i; done
|
||||
|
||||
.. note::
|
||||
|
||||
The Intel QAT device plugin only supports QAT VF resources in the current
|
||||
release.
|
||||
|
||||
#. Assign the ``intelqat`` label to the node (worker-0 in this example).
|
||||
|
||||
::
|
||||
|
||||
$ NODE=worker-0
|
||||
$ system host-lock $NODE
|
||||
$ system host-label-assign $NODE intelqat=enabled
|
||||
$ system host-unlock $NODE
|
||||
|
||||
#. After the node becomes available, verify the Intel QAT device plugin is
|
||||
registered.
|
||||
|
||||
::
|
||||
|
||||
$ kubectl describe node $NODE | grep qat.intel.com/generic
|
||||
qat.intel.com/generic: 10
|
||||
.intel.com/generic: 10
|
||||
|
||||
-------------------------------
|
||||
Consume Intel QAT device plugin
|
||||
-------------------------------
|
||||
|
||||
#. Build the DPDK image.
|
||||
|
||||
::
|
||||
|
||||
$ git clone https://github.com/intel/intel-device-plugins-for-kubernetes.git
|
||||
$ cd demo
|
||||
$ ./build-image.sh crypto-perf
|
||||
|
||||
This command produces a Docker image named ``crypto-perf``.
|
||||
|
||||
#. Deploy a pod to run an example DPDK application named
|
||||
``dpdk-test-crypto-perf``.
|
||||
|
||||
In the pod specification file, add the container resource request and
|
||||
limit.
|
||||
|
||||
For example, use ``qat.intel.com/generic: <number of devices>`` for a
|
||||
container requesting Intel QAT devices.
|
||||
|
||||
|
||||
For a DPDK-based workload, you may need to add a hugepage request and limit.

This section describes the steps for using |QAT| device plugin.
|

specification file can be modified for required resource request and limit.
|

The ``qat.intel.com/asym-dc: <number of devices>`` field is used to
|
||||
configure the requested |QAT| virtual functions.
|
||||
|
||||
For a |DPDK|-based workload, you may need to add a hugepage request and
|

Kubernetes Intel GPU Device Plugin Configuration
|
||||
================================================
|
||||
|
||||
This document describes how to enable the Intel GPU device plugin in StarlingX
|
||||
and schedule pods on nodes with an Intel GPU.
|
||||
|
||||
------------------------------
|
||||
Enable Intel GPU device plugin
|
||||
------------------------------
|
||||
|
||||
You can pre-install the ``intel-gpu-plugin`` daemonset as follows:
|
||||
|
||||
#. Launch the ``intel-gpu-plugin`` daemonset.
|
||||
|
||||
Add the following lines to the ``localhost.yaml`` file before playing the
|
||||
Ansible bootstrap playbook to configure the system.
|
||||
|
||||
::
|
||||
|
||||
k8s_plugins:
|
||||
intel-gpu-plugin: intelgpu=enabled
|
||||
|
||||
#. Assign the ``intelgpu`` label to each node that should have the Intel GPU
|
||||
plugin enabled. This will make any GPU devices on a given node available for
|
||||
scheduling to containers. The following example assigns the ``intelgpu``
|
||||
label to the worker-0 node.
|
||||
|
||||
::
|
||||
|
||||
$ NODE=worker-0
|
||||
$ system host-lock $NODE
|
||||
$ system host-label-assign $NODE intelgpu=enabled
|
||||
$ system host-unlock $NODE
|
||||
|
||||
#. After the node becomes available, verify the GPU device plugin is registered
|
||||
and that the available GPU devices on the node have been discovered and reported.
|
||||
|
||||
::
|
||||
|
||||
$ kubectl describe node $NODE | grep gpu.intel.com
|
||||
gpu.intel.com/i915: 1
|
||||
gpu.intel.com/i915: 1
|
||||
|
||||
-------------------------------------
|
||||
Schedule pods on nodes with Intel GPU
|
||||
-------------------------------------
|
||||
|
||||
Add a ``resources.limits.gpu.intel.com`` to your container specification in order
|
||||
to request an available GPU device for your container.
|
||||
|
||||
::
|
||||
|
||||
...
|
||||
spec:
|
||||
containers:
|
||||
- name: ...
|
||||
...
|
||||
resources:
|
||||
limits:
|
||||
gpu.intel.com/i915: 1
|
||||
|
||||
|
||||
The pods will be scheduled to the nodes with available Intel GPU devices. A GPU
|
||||
device will be allocated to the container and the available GPU devices will be
|
||||
updated.
|
||||
|
||||
::
|
||||
|
||||
$ kubectl describe node $NODE | grep gpu.intel.com
|
||||
gpu.intel.com/i915: 1
|
||||
gpu.intel.com/i915: 0
|
||||
|
||||
