* ``VGPU_HOST_DRIVER_VERSION`` - The NVIDIA vGPU Manager version downloaded from the NVIDIA Software Portal.
* ``OS_TAG`` - This must match the Guest OS version.
For RedHat OpenShift, specify ``rhcos4.x`` where _x_ is the supported minor OCP version.

.. note::
The driver container image tag for OpenShift has changed after the OCP 4.19 release.
Refer to `OpenShift Container Platform 4.19 Release Notes section 1.4.5 <https://docs.redhat.com/en/documentation/openshift_container_platform/4.19/html/release_notes/ocp-4-19-release-notes#ocp-4-19-rhcos-split-layers_release-notes>`_,
`RHEL Versions Utilized by RHEL CoreOS and OCP <https://access.redhat.com/articles/6907891>`_,
and `Split RHCOS into layers: /etc/os-release <https://github.com/openshift/enhancements/blob/master/enhancements/rhcos/split-rhcos-into-layers.md#etcos-release>`_
for more information.


For RedHat OpenShift 4.18 or earlier, specify ``rhcos4.x`` where _x_ is the supported minor OCP version.

.. code-block:: console

$ export PRIVATE_REGISTRY=my/private/registry VGPU_HOST_DRIVER_VERSION=580.82.07 OS_TAG=rhcos4.18
$ export PRIVATE_REGISTRY=my/private/registry VGPU_HOST_DRIVER_VERSION=580.82.07 OS_TAG=rhcos4.18

For OpenShift 4.19 and later, specify ``rhel9.6`` instead.

.. code-block:: console

$ export PRIVATE_REGISTRY=my/private/registry VGPU_HOST_DRIVER_VERSION=580.82.07 OS_TAG=rhel9.6
.. note::

The recommended registry to use is the Integrated OpenShift Container Platform registry.
