I guess the credential stored there will be used to talk to swift. Is that correct? In general, it is insecure to store user credential inside a VM, because anyone can take a snapshot of the VM and boot another VM from the snapshot. Maybe storing a scoped
credential in the config file could mitigate the security risk. Not sure if there is a better solution.<o:p></o:p></span></p>

<p class="MsoNormal">Hi all, <o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">In order to add registry v2 to bay nodes[1], authentication information is needed for the registry to upload and download files from swift. The swift storage-driver in registry now needs the parameters as described in [2]. User password
is needed. How can we get the password? <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">1. Let user pass password in baymodel-create.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">2. Use user token to get password from keystone<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Is it suitable to store user password in db?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">It may be insecure to store password in db and expose it to user in a config file even if the password is encrypted. Heat store user password in db before, and now change to keystone trust[3]. But if we use keystone trust, the swift storage-driver
does not support it. If we use trust, we expose magnum user's credential in a config file, which is also insecure.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Is there a secure way to implement this bp?<o:p></o:p></p>
