  1. You need to grab the latest ignition on your Intel bastion:
curl -k -H "Accept: application/vnd.coreos.ignition+json;version=3.4.0" -o /var/www/html/ignition/worker.ign https://localhost:22623/config/worker
restorecon -R /var/www/html/ignition/
  1. Clone git clone https://github.com/ocp-power-automation/ocp4-upi-multiarch-compute
  2. Change directory to ocp4-upi-multiarch-compute/tf/add-powervm-workers
  3. Create a tfvars file
auth_url    = "https://<vl>:5000/v3"
user_name   = ""
password    = ""
insecure    = true
tenant_name = "ocp-qe"
domain_name = "Default"

network_name                = "vlan"
ignition_ip                 = "10.10.19.16"
resolver_ip                 = "10.10.19.16"
resolve_domain              = "pavan-421ec3.ocpqe"
power_worker_prefix         = "rhcos9-worker"
flavor_id                   = "8ee61c00-b803-49c5-b243-62da02220ed6"
image_id                    = "f48b00dc-d672-4f9a-bac8-a3383bea4a3f"
openstack_availability_zone = "e980"

# the number of workers to create
worker_count = 1
  1. Run Terraform terraform apply -var-file=data/var.tfvars
  2. On a Power bastion node, you will need to add dhcpd entry to /etc/dhcp/dhcpd.conf and named forwarder pointing to your Intel bastion forwarders { 8.8.4.4; }; in /etc/named.conf. Then restart each using systemctl restart dhcpd and systemctl restart named.
  3. Start the VM is created in the ‘Stopped’ state, you can manually ‘Start’ it.
  4. Approve the CSRs that are generated.
