Deploy an additional nova cell v2
Warning
Multi cell support is only supported in Stein and later versions.
The different sections in this guide assume that you are ready to deploy a new overcloud, or already have installed an overcloud (min Stein release).
Note
Starting with CentOS 8 and the TripleO Stein release, podman is the CONTAINERCLI to be used in the following steps.
The minimum requirement for having multiple cells is to have a central OpenStack controller cluster running all controller services. Additional cells will have cell controllers running the cell DB, cell MQ and a nova cell conductor service. In addition there are 1..n compute nodes. The central nova conductor service acts as a super conductor of the whole environment.
For more details on the cells v2 layout check Cells Layout (v2)
