Containers based Undercloud DeploymentΒΆ

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 docker based undercloud architecture is not very different from the baremetal/VM based one. The services deployed in the traditional baremetal undercloud are also deployed in the docker 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.
