After you add machines to your new bare metal managed cluster as described in Add a machine, you can create a Ceph cluster on top of this managed cluster using the Mirantis Container Cloud web UI.
The procedure below enables you to create a Ceph cluster with minimum three Ceph nodes that provides persistent volumes to the Kubernetes workloads in the managed cluster.
To create a Ceph cluster in the managed cluster:
Log in to the Container Cloud web UI with the writer permissions.
Switch to the required project using the Switch Project action icon located on top of the main left-side navigation panel.
In the Clusters tab, click the required cluster name. The Cluster page with the Machines and Ceph clusters lists opens.
In the Ceph Clusters block, click Create Cluster.
Configure the Ceph cluster in the Create New Ceph Cluster wizard that opens:
