<div dir="ltr">Hi Thiago,<br><br>Yes Docker could be used to replace the virtualization layer on the Compute Node, it's the case if we configure Nova to use the Docker Driver.<br><br>In our case, we are orchestrating Docker in OpenStack via Heat. We used a VM as a docker host for many reasons :<br>
<br> - It is a way to economize IP addresses :<br><br>If the docker host is a physical server, every container needs a floating IP (to be reachable from outside). When the docker host is a VM, we associate one floating IP to it and we can access to containers via binding ports (@VM-floatingIP:container-binding-port).<br>
<br> - To achieve stronger isolation and security<br><br> - To easily integrate docker with existing VM-based management and monitoring tools<br><br> - We think that Docker and virtualization could also be complementary.<br>
<br><br>Thank you for the question<br>We will update the document to clarify these points.<br><br><a href="https://github.com/MarouenMechtri/Docker-containers-deployment-with-OpenStack-Heat">https://github.com/MarouenMechtri/Docker-containers-deployment-with-OpenStack-Heat</a><br>
