<p class="MsoNormal">Hi All<o:p></o:p></p>
<p class="MsoNormal"> here is the proposal for enabling intel-gpu-plugin on StarlingX , welcome suggestion and advise.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The background:<o:p></o:p></p>
<p class="MsoNormal">As a part of resource management, kubernetes provides a device plugin framework [2] for vendors to advertise their resources to the kubelet since version 1.8. StarlingX has already supported SR-IOV CNI plugins now [3].<o:p></o:p></p>
<p class="MsoNormal" style="text-align:justify;text-justify:inter-ideograph">Intel-gpu-plugins is a device plugin implementation [4] for intel GPU (with driver i915). Users could deploy their pods with Intel GPU resource requests or limits, if intel-gpu-plugins
was integrated into StarlingX.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">proposal:<o:p></o:p></p>
<p class="MsoNormal">Deploy intel-gpu-plugins as a daemon set with node selector “intelgpu: enabled”. Kubernetes label “intelgpu: enabled” will be set automatically once the node detected supported GPU device.
<o:p></o:p></p>
<p class="MsoNormal">Details are shown as follows: <o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">1.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Build StarlingX plugin docker image based on [5], the implement in starlingx are [6] and [7]<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">2.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Deploy Intel-gpu-plugins daemon set in tasks “bringup_kubemaster” after kubernetes master has been initialized during ansible bootstrap process. Add value “import_plugins” and value list “kube_plugins” as condition of deploying Intel-gpu-plugins
daemon set, so user could determine whether Intel-gpu-plugins would be enabled. Create file “/etc/platform/enabled_kube_plugins” and write list “kube_plugins” into the file after active Intel-gpu-plugin daemon if “import_plugins” is true. Partical Implement
is [8]<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">3.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Detect supported GPU device with the help of sysinv agent and request to set kubernetes label “intelgpu: enabled” for specific node by calling sysinv conductor rpcapi. Sysinv conductor will check file “/etc/platform/enabled_kube_plugins”,
and set kubernetes label if the file is exist and intel-gpu-plugins is in list. Partial implement is [9]<o:p></o:p></p>
