Add machines to the MOS cluster

Add machines to the MOS cluster

After you add bare metal hosts to the MOS managed cluster, create Kubernetes machines in your cluster using the Mirantis Container Cloud web UI.

For the detailed procedure, refer to Mirantis Container Cloud Operations Guide: Add a machine.

When adding the machines, verify that you label the Kubernetes nodes according to the OpenStack node roles:

OpenStack node roles

Description

Kubernetes labels

Minimal count

OpenStack control plane

Hosts the OpenStack control plane services such as database, messaging, API, schedulers, conductors, L3 and L2 agents.

openstack-control-plane=enabled
openstack-gateway=enabled
openvswitch=enabled

3

OpenStack compute

Hosts the OpenStack compute services such as libvirt and L2 agents.

openstack-compute-node=enabled
openvswitch=enabled (for a deployment with Open vSwitch as a back end for networking)

Varies

Note

MOS allows collocating components on the same host, for example, Ceph OSD and OpenStack compute. For details, see Mirantis Container Cloud Operations Guide: Add, remove, or reconfigure Ceph nodes.
