oVirt Platform Customization

Beyond the platform-agnostic install-config.yaml properties, the installer supports additional, ovirt-specific properties.

Cluster-scoped properties

  • ovirt_cluster_id (required string): The Cluster where the VMs will be created.
  • ovirt_storage_domain_id (required string): The Storage Domain ID where the VM disks will be created.
  • ovirt_network_name (required string): The network name where the VM nics will be created.
  • vnicProfileID (required string): The ID of the vNic profile used for the VM network interfaces. This can be inferred if the cluster network has a single profile.
  • api_vip (required string): An IP address on the machineNetwork that will be assigned to the API VIP.
  • ingress_vip (required string): An IP address on the machineNetwork that will be assigned to the Ingress VIP.

Machine pools

  • cpu (optional object): Defines the CPU of the VM.
    • cores (required integer): The number of cores. Total vCPUS is cores * sockets.
    • sockets (required integer): The number of sockets. Total vCPUS is cores * sockets.
  • memoryMB (optional integer): Memory of the VM in MiB.
  • instanceTypeID (optional string): The VM instance-type.
  • osDisk (optional string): Defines the first and bootable disk of the VM.
    • sizeGB (required number): Size of the disk in GiB.
  • vmType (optional string): The VM workload type. One of high-performance, server or desktop.

Installing to Existing VPC & Subnetworks

The installer can use an existing VPC and subnets when provisioning an OpenShift cluster. A VPC will be inferred from the provided subnets. For a standard installation, a private and public subnet should be specified. (see example below). Both of the subnets must be within the IP range specified in networking.machineNetwork.

Examples

Some example install-config.yaml are shown below. For examples of platform-agnostic configuration fragments, see here.

Minimal

An example minimal install config is:

apiVersion: v1
baseDomain: example.com
metadata:
  name: test-cluster
platform:
  ovirt:
    api_vip: 10.46.8.230
    ingress_vip: 10.46.8.232
    ovirt_cluster_id: 68833f9f-e89c-4891-b768-e2ba0815b76b
    ovirt_storage_domain_id: ed7b0f4e-0e96-492a-8fff-279213ee1468
    ovirt_network_name: ovirtmgmt
    vnicProfileID: 3fa86930-0be5-4052-b667-b79f0a729692
pullSecret: '{"auths": ...}'
sshKey: ssh-ed25519 AAAA...

Custom machine pools

An example install config with custom machine pools:

apiVersion: v1
