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
