vSphere Platform Customization

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

Cluster-scoped properties

  • vCenter (required string): The domain name or IP address of the vCenter.
  • username (required string): The username to use to connect to the vCenter.
  • password (required string): The password to use to connect to the vCenter.
  • datacenter (required string): The name of the datacenter to use in the vCenter.
  • defaultDatastore (required string): The default datastore to use for provisioning volumes.
  • folder (optional string): The absolute path of an existing folder where the installer should create VMs. The absolute path is of the form /example_datacenter/vm/example_folder/example_subfolder. If a value is specified, the folder must exist. If no value is specified, a folder named with the cluster ID will be created in the datacenter VM folder.
  • resourcePool (optional string): The absolute path of an existing resource pool where the installer should create VMs. The absolute path is of the form /example_datacenter/host/example_cluster/Resources/example_resource_pool/optionally_sub_resource_pool. If a value is specified, the resource pool must exist. If no value is specified, resources will be installed in the root of the cluster /example_datacenter/host/example_cluster/Resources.

Machine pools

  • osDisk (optional object):
    • diskSizeGB (optional integer): The size of the disk in gigabytes (GB).
  • cpus (optional integer): The total number of virtual processor cores to assign a vm.
  • coresPerSocket (optional integer): The number of cores per socket in a vm. The number of vCPUs on the vm will be cpus/coresPerSocket (default is 1).
  • memoryMB (optional integer): The size of a VM's memory in megabytes.
  • disk_type (optional string): DiskType is the name of the disk provisioning type, valid values are thin, thick, and eagerZeroedThick. When not specified, it will be set according to the default storage policy of vsphere.

Examples

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

Minimal

An example minimal vSphere install config is:

apiVersion: v1
baseDomain: example.com
metadata:
  name: test-cluster
platform:
  vSphere:
    vCenter: your.vcenter.example.com
    username: username
    password: password
    datacenter: datacenter
    defaultDatastore: datastore
pullSecret: '{"auths": ...}'
sshKey: ssh-ed25519 AAAA...

Custom Machine Pools

An example vSphere install config with custom machine pools:

apiVersion: v1
baseDomain: example.com
controlPlane:
  name: master
  platform:
    vsphere:
      cpus: 8
      coresPerSocket: 2
      memoryMB: 24576
      osDisk:
        diskSizeGB: 512
  replicas: 3
compute:
- name: worker
  platform:
    vsphere:
      cpus: 8
      coresPerSocket: 2
      memoryMB: 24576
      osDisk:
        diskSizeGB: 512
  replicas: 5
metadata:
  name: test-cluster
platform:
  vSphere:
    vCenter: your.vcenter.example.com
    username: username
    password: password
    datacenter: datacenter
    defaultDatastore: datastore
pullSecret: '{"auths": ...}'
sshKey: ssh-ed25519 AAAA...
