<li class="fragment">DevStack<span class="fragment" style="color:red">, but</span></li>
|
|
<li class="fragment">... not very aligned with real-world</li>
|
|
<li class="fragment">... all in one</li>
|
|
<li class="fragment">... take time to configure</li>

<li class="fragment">... rely on master branch</li>

<h2>second idea: bootstrap-openstack</h2>
|
|
<ul>
|
|
<li class="fragment">Start OpenStack on top of our OVH OpenStack</li>
|
|
<li class="fragment">... it is quick (5m)</li>
|
|
<li class="fragment">... multi node by default</li>
|
|
<li class="fragment">... easy to read, easy to tune</li>

<li class="fragment">OpenTofu starts 5 instances

<li class="fragment">1 controler (named k8s)</li>
|
|
<li class="fragment">2 compute nodes</li>
|
|
<li class="fragment">2 network nodes</li>
|
|
</ul>
|
|
</li>
|
|
<li class="fragment">... use cloud-init for setup</li>
|
|
<li class="fragment">... rely on pre-compiled packages (.deb and docker)</li>
|
|
<li class="fragment">... pre-create image, flavors, etc.</li>
|
|
<li class="fragment">... can use real public IPs</li>
