<span style="font-size:10.0pt;font-family:"Arial",sans-serif">I'm working on setting a CI system for IBM storage products.</span><br>
<span style="font-size:10.0pt;font-family:"Arial",sans-serif">Currently I'm dealing with Nodepool.</span><br>

<span style="font-size:10.0pt;font-family:"Arial",sans-serif">The problem is that no one put the ssh key in theses users?</span><br>
