Prepare for the 'Bare Metal' environment on vSphere

  1. Copy the rhcos-X.X.X-x86_64-installer.x86_64.iso & Red Hat Enterprise Linux 8 iso to an ESXi datastore
  2. Create a new Port Group called 'OCP' under Networking
  3. Create 3 Control Plane virtual machines with minimum settings:
    • Name: ocp-cp-# (Example ocp-cp-1)
    • 8vcpu
    • 32GB RAM
    • 120GB HDD
    • NIC connected to the OCP network
    • Load the rhcos-X.X.X-x86_64-installer.x86_64.iso image into the CD/DVD drive
  4. Create 3 Worker virtual machines (or more if you want) with minimum settings:
    • Name: ocp-w-# (Example ocp-w-1)
    • 8vcpu
    • 32GB RAM
    • 120GB HDD
    • NIC connected to the OCP network
    • Load the rhcos-X.X.X-x86_64-installer.x86_64.iso image into the CD/DVD drive
  5. Create 3 Infra virtual machines (or more if you want) with minimum settings:
    • Name: ocp-w-# (Example ocp-w-1)
    • 16vcpu
    • 64GB RAM
    • 120GB HDD
    • NIC connected to the OCP network
    • Load the rhcos-X.X.X-x86_64-installer.x86_64.iso image into the CD/DVD drive
  6. Create a Bootstrap virtual machine (this vm will be deleted once installation completes) with minimum settings:
    • Name: ocp-boostrap
    • 4vcpu
    • 8GB RAM
    • 120GB HDD
    • NIC connected to the OCP network
    • Load the rhcos-X.X.X-x86_64-installer.x86_64.iso image into the CD/DVD drive
  7. Create a helper virtual machine (bastionn) with minimum settings:
    • Name: ocp-helper
    • 4vcpu
    • 4GB RAM
    • 120GB HDD
    • NIC1 connected to the VM Network (LAN)
    • NIC2 connected to the OCP network
    • Load the CentOS_8.iso image into the CD/DVD drive
  8. Boot all virtual machines so they each are assigned a MAC address
  9. Shut down all virtual machines except for 'ocp-helper'
  10. Use the VMware ESXi dashboard to record the MAC address of each vm, these will be used later to set static IPs

No openshift installer ISO image needs to be loaded into the CD/DVD drive. Instead of booting from the CD/DVD, virtual machines should boot from the network using PXE.
