We use this quite a lot and it works well, is accesable from the the API, CLI and Heat templates. We even kludged a little addition to the Horizon launch workflow (I can provide it as an example but isn't very robust ).<br><br></div><div>But, if you are really looking to avoid DHCP (rather than just the dynamic IP part) you'll need to s things a bit differently. I've not tried this, but I think using a 'config drive' and passing in a user data script to statically configure the interface(s) would be the way to go, note you'll need cloud-init (or a similar script) in the image to execute the user data and you can't rely on the metadata service because that relies on the network being setup so it can reach the metadata server over http.<br><br></div><div>-Jon<br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="gmail_extra"><div><div><div dir="ltr"></div></div></div>

<div>Hi,</div>
<div><br>
</div>
<div>I would like to assign a static IP/subnet and the gateway of my choice to an instance (both windows and linux) while lunching it instead of using built-in DHCP.</div>
<div>What are my options in OpenStack to achieve it?</div>
<div><br>
</div>
<div>Regards,</div>
