Prepare the OVF template

1. Change the directory to the kaas-bootstrap folder.

2. Download the ISO image of the required operating system (OS):

   • Ubuntu 20.04 DVD ISO from Ubuntu images

   • RHEL 7.8, 7.9, or 8.4 ^TechPreview DVD ISO from the RedHat Customer Portal

   • Technology Preview: CentOS 7.9 DVD ISO from the CentOS mirrors

3. Export the following variables:

   • The path to the downloaded ISO file.

   • The vSphere cluster name.

   • The OS name: rhel or centos.

   • The OS version: 7.8, 7.9, or 8.4 ^TechPreview for RHEL; 7.9 for CentOS.

   • Optional. The virt-who user name and password for RHEL deployments.

   For example, for RHEL:

   export KAAS_VSPHERE_ENABLED=true
   export VSPHERE_RO_USER=virt-who-user
   export VSPHERE_RO_PASSWORD=virt-who-user-password
   export VSPHERE_PACKER_ISO_FILE=$(pwd)/iso-file.dvd.iso
   export VSPHERE_CLUSTER_NAME=vsphere-cluster-name
   export VSPHERE_PACKER_IMAGE_OS_NAME=rhel
   export VSPHERE_PACKER_IMAGE_OS_VERSION=7.9
   

4. Prepare the OVF template:

   ./bootstrap.sh vsphere_template
   

5. In templates/vsphere/machines.yaml.template:

   • Define SET_VSPHERE_TEMPLATE_PATH prepared in the previous step

   • Modify other parameters as required

   spec:
     providerSpec:
       value:
         apiVersion: vsphere.cluster.k8s.io/v1alpha1
         kind: VsphereMachineProviderSpec
         rhelLicense: <rhel-license-name>
         network:
           devices:
           - dhcp4: true
             dhcp6: false
         template: <SET_VSPHERE_TEMPLATE_PATH>
   

   Note

   The <rhel-license-name> value is the RHEL license name defined in rhellicenses.yaml.tempalte, defaults to kaas-mgmt-rhel-license. Remove or comment out this parameter for CentOS deployments.
