Step 3: Provide Inputs to the Files in the ``project_default`` Directory
===========================================================================

Omnia is now deployed using a project-based approach. Once the ``omnia_core`` container is deployed, all the input files needed for the cluster will be available in the ``/opt/omnia/input/project_default`` directory on the NFS share.
Before moving on to the next step, which is running the ``prepare_oim.yml`` playbook, you must provide inputs for all the files in this directory.

Here's an example of the input files present in the ``project_default`` directory:

Input Templates for Deployment
===============================

You can use the provided input templates to simplify deployment. Choose the template that matches your cluster architecture and telemetry requirements:

* **x86_64 Slurm cluster with telemetry**: Use the templates available at: :file:`omnia/examples/input_template/bare_metal_slurm/x86_64/with_service_k8s`

* **x86_64 Slurm controller node with ARM-based Slurm nodes and telemetry**:  Use the templates available at: :file:`omnia/examples/input_template/bare_metal_slurm/aarch64/with_service_k8s`

* **x86_64 Slurm cluster without telemetry**: Use the templates available at: :file:`omnia/examples/input_template/bare_metal_slurm/x86_64/without_service_k8s`

* **x86_64 Slurm controller node with ARM-based Slurm nodes without telemetry**: Use the templates available at: :file:`omnia/examples/input_template/bare_metal_slurm/aarch64/without_service_k8s`

Default Values Assumed in these Templates (change if needed):
---------------------------------------------------------------

* Virtual address for Kubernetes cluster: ``172.16.0.1``
* OIM PXE NIC IP address: ``172.16.0.254``
* Mapping file path (provided in the same folder): ``pxe_mapping_file.csv``
* External NFS share for all Omnia workflows:  
  IP address: ``172.16.0.253``, Path: ``/mnt/share/omnia``
* NFS share for HA on service Kubernetes cluster:  
  IP addresses: ``172.16.0.252``, Path: ``/mnt/share/omnia_k8s``

Additional values you must provide:
------------------------------------

* **Local repository configuration:**  
   * ``rhel_os_url_x86_64`` – BaseOS, AppStream, and CRB repository details for x86_64 node provisioning  
   * ``rhel_os_url_aarch64`` – BaseOS, AppStream, and CRB repository details for aarch64 node provisioning

.. note:: If the RHEL subscription on the OIM is not enabled, the ``rhel_os_url_x86_64`` and ``rhel_os_url_aarch64`` parameters are mandatory. 

* **Telemetry configuration (if enabled):**  
   * ``csi_powerscale_driver_secret_file_path`` – Powerscale driver secret file  
   * ``csi_powerscale_driver_values_file_path`` – Powerscale driver values file
