Containers based Undercloud Deployment
|
|
======================================
|
|
|
|
The requirements for a containerized undercloud are the same as for any other
|
|
undercloud deployment. The real difference is in where the undercloud services
|
|
will be deployed (containers vs base OS).
|
|
|
|
The undercloud architecture based on Moby_ (also Podman_ as of Stein) containers
|
|
is not very different from the baremetal/VM based one. The services deployed in
|
|
the traditional baremetal undercloud are also deployed in the containers based
|
|
one.

|
|
|
|
One obvious difference between these two types of deployments is that the
|
|
openstack services are deployed as containers in a container runtime rather than
|
|
directly on the host operating system. This reduces the required packages in
|
|
the host to the bare minimum for running the container runtime and managing the
|
|
base network layer.
