Creating the OpenShift Container Platform Discovery ISO Image

Use these instructions to create a minimal ISO for installing OpenShift Container Platform on OCI.

The "openshift-install" program, available from Red Hat, creates a minimal ISO image file on your local machine which you use to create OpenShift cluster nodes in OCI. You can download the installer from the OpenShift Installer and CLI Downloads download page.

For instructions on creating the ISO image, see Creating configuration files for installing a cluster on OCI (Red Hat documentation).

After creating the ISO image, complete the following steps to create an OCI Compute service custom image for node provisioning.

  1. Upload the minimal ISO image to an Object Storage bucket. See Creating an Object Storage Bucket and Uploading an Object Storage Object to a Bucket for instructions.
  2. Create a custom image with image type QCOW2 in the Compute service using the uploaded ISO image from the previous step. See Managing Custom Images for instructions.
  3. Important: After the custom image is created, go to Edit image capabilities on the details page for the image and ensure that the Firmware options are as follows:
    • UEFI_64: enabled
    • BIOS: disabled
