The drive will contain the user data. Its an alternative to the metadata service and isn't a "normal" drive. Its created, mounted, and populated by Nova.<br>

<div>config_drive: true just tells the instance to mount the drive. You pass data via the user_data property. <br>

Thanks Randall that is what I was thinking.<br>
<br>
But I am confused. <br>
<br>
When booting an instance with nova boot, I can configure a local file/directory to be mounted as a config drive on the instance upon boot. I can also provide information and commands regularly through the user_data<br>
<br>
Through Heat I can provide configuration through user_data. And I can also mount a config_drive.<br>
<br>
Where do I define what that config_drive contains? <br>
<br>

<div class="PlainText">I have been looking for a working example to create Heat stack with a
<br>
config_drive attached.<br>
<br>
I know it is possible to deploy a nova instance with the CLI [1]<br>
<br>
I see that OS::Nova::Server has a config_drive property that is a <br>
Boolean value [2]<br>
<br>
What I cannot find is how this can be used. Where is the path defined <br>
for the config file?<br>
Or am I completely missing what and how this should be used?<br>
<br>
Anyone with more info on this - I would be highly grateful.<br>
<br>
Thanks.<br>
