Thanks for your question. I personally don't have an answer, but I<br>
think we definitely should bring up the possibility of dockerization for<br>
Sahara at the design summit next week. It may be something we want to<br>
formalize for Kilo. Will you be at the summit?<br>
<br>
Just to be clear, are you running Sahara itself in a container, or<br>
launching node instances in containers?<br>
<br>
I'll take a look and see if I can find anything useful about the ip<br>
assignment/hostname sequence for node instances during launch.<br>
<br>
Best,<br>
<br>
Trevor<br>
