vsphereupi-openshift

Pre-Requisites:

  • Clone repo to the infra/helper host (running DNS/DHCP/PXE) and run scripts locally there.
  • Installation supports configuring static IPs and will inject them via ignition configuration.
  • Installation also supports disconnected mode. Be sure to run the optional scripts which will build the locally mirrorred registry.
  • Any optional scripts such as DNS and local registry configuration can be omitted especially if you plan to configure these manually.

Before executing:

  • Copy 0_ocp4_vsphere_upi_init_vars.template as 0_ocp4_vsphere_upi_init_vars and adapt the configuration to your environment.

To install:

  • Run each shell script in order.
  • Normally, steps 1 - 8 would be the only steps needed to fully install a cluster.
    • Scripts identified with xxx_bm_xxx are meant for a bare-metal installation on Vsphere via PXE using the RHCOS raw image.
    • Scripts identified with xxx_tf_xxx are meant for a terraform installation on Vsphere using the RHCOS OVA.
  • Step 8 will allow you to perform a kubeadmin password reset, if needed.
  • Step 9 will destroy a provisioned cluster.
