Deploying Bare Metal clusters with Fusion Data Foundation

You can create a Hosted Control Plane cluster by using Bare Metal hosts either through the OpenShift® Console or the Hosted Control Plane CLI.

1. Go to ACM user interface.
2. Go to Infrastructure > Clusters > Create cluster.
3. Select Host Inventory and then Hosted.
4. Enter the credentials.
   The credentials should include the following:

   • cloud.openshift.com
   • cp.icr.io
   • quay.io
   • registry.connect.redhat.com
   • registry.redhat.io
5. Enter Cluster name.
   Important: It is crucial that the cluster name is the same name used in the network planning. Do not use a name that does not have an alias entry. The cluster is a part of the base domain. For example, mydomain.com. Controller and Infrastructure availability are environment dependent.

   Though the recommendation is to have 3 nodes for a resilient cluster, you can have a single node Hosted Control Plane cluster.

6. Enter Namespace. It is the namespace of the infrastructure environment of the hosts.
7. Enter Labels. These are the labels found on hosts in this particular infrastructure environment. To ensure certain hosts are in a particular cluster, use the labels. Otherwise, a random host from that infrastructure environment gets chosen.
8. Enter the Networking type.
   The value is environment dependent, but you can choose LoadBalancer type for resilience. The SSH public key must be the same that you used during host import.
9. Open the YAML and add the following in the spec section: HCP cluster to use the specially created Local Volume Storage for HCP

   
   spec:
     etcd:
       managed:
         storage:
           persistentVolume:
             size: 8Gi
             storageClassName: lvms-hcp-etcd
           type: PersistentVolume
       managementType: Managed

   It causes the Hosted Control Plane cluster to use the Local Volume Storage created for it.

10. Click Finish.
    The cluster creation starts and it can take up to half an hour. After the nodepool hosts are in the ready state, add the load balancer for the console to be available.
