Oh ok! Yes, if you only focus on the control plan, the answer is yes, I’m using kolla-ansible and it’s working really well. It helped us to bring more services online more quickly and solved our lifecycle management that was kind of tricky.<br><br>I’m using a Blue/Green deployement method and yes I’m using multinode form.<br><br>Remember that kolla-ansible is a simple shell script wrapping ansible-playbook and that if you’re curious of what the playbooks look like you just have to install it (or goes on github) with pip and then get your hands on it.<br><br>Kind regards.<br><div class="gmail_quote"><div dir="ltr">Le ven. 18 mai 2018 à 22:07, Fox, Kevin M <<a href="mailto:Kevin.Fox@pnnl.gov">Kevin.Fox@pnnl.gov</a>> a écrit :<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div dir="ltr">Hi All,
<div><br>
</div>
<div>We want to deploy our private cloud using OpenStack as highly available (zero downtime (ZDT) - in normal course of action and during upgrades as well) production grade environment. We came across following tools.</div>
<div><br>
</div>
<div>
<ul>
<li>We thought of using <i>Kolla-Kubernetes</i> as deployment tool, but we got feedback from Kolla IRC channel that this project is being retired. Moreover, we couldn't find latest documents having multi-node deployment steps and, High Availability support
was also not mentioned at all anywhere in the documentation.</li><li>Another option to have Kubernetes based deployment is to use OpenStack-Helm, but it seems the OSH community has not made OSH 1.0 officially available yet.</li><li>Last option, is to use <i>Kolla-Ansible</i>, although it is not a Kubernetes deployment, but seems to have good community support around it. Also, its documentation talks a little about production grade deployment, probably it is being used in production
grade environments.<br>
</li></ul>

If you folks have used any of these tools for deploying OpenStack to fulfill these requirements: HA and ZDT, then please provide your inputs specifically about HA and ZDT support of the deployment tool, based on your experience. And please share if you have
any reference links that you have used for achieving HA and ZDT for the respective tools.</div>

Lastly, if you think we should think that we have missed another more viable and stable options of deployment tools which can serve our requirement: HA and ZDT, then please do suggest the same.</div>
