<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal">Regarding the question below:<o:p></o:p></p>
<p class="MsoNormal"> Is there way I can enable application-isolation across all the worker nodes including new nodes to be added in future?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Application-isolated CPUs are configured on a per-host basis. When new nodes are added, they will need to be explicitly configured.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there a specific use-case that you have where it would be beneficial for new nodes to automatically inherit the config of an existing node? There was an old capability where host profiles could be created and applied to new nodes. But
this proved problematic as exact hardware matches were not guaranteed. As a result, this capability was abandoned a long time ago.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
