RHEL 10.0 x86_64 - Slurm + Kubernetes (full deployment)

This example demonstrates a single-architecture full deployment of Slurm(slurm_custom) and Kubernetes(service_k8s) supporting only x86_64 nodes.

RHEL 10.0 Multi-Arch cluster

This example demonstrates a multi-architecture deployment supporting both x86_64 and aarch64 nodes.

Slurm-only cluster

Deploys a traditional HPC cluster with Slurm scheduling, LDAP, openmpi and ucx. No Kubernetes.

Sample software_config.json: Slurm-only cluster
{
    "cluster_os_type": "rhel",
    "cluster_os_version": "10.0",
    "repo_config": "partial",
    "softwares": [

        {"name": "slurm_node"},
        {"name": "login_node"},
        {"name": "login_compiler_node"}
    ]
}

Kubernetes + telemetry only (no Slurm)

Deploys a Kubernetes cluster with the full telemetry pipeline for infrastructure monitoring without a job scheduler.

Sample software_config.json: Kubernetes + telemetry only
{
    "cluster_os_type": "rhel",
    "cluster_os_version": "10.0",
    "repo_config": "partial",
    "softwares": [
        {"name": "default_packages", "arch": ["x86_64"]},
        {"name": "admin_debug_packages", "arch": ["x86_64"]},
        {"name": "service_k8s", "version": "1.35.1", "arch": ["x86_64"]},
        {"name": "csi_driver_powerscale", "version":"v2.16.0", "arch": ["x86_64"]},
        {"name": "ldms", "arch": ["x86_64"]},
        {"name": "additional_packages", "arch": ["x86_64"]}
    ],
    "service_k8s": [
        {"name": "service_kube_control_plane_first"},
        {"name": "service_kube_control_plane"},
        {"name": "service_kube_node"}
    ],
     "additional_packages":[
        {"name": "service_kube_control_plane_first"},
        {"name": "service_kube_control_plane"},
        {"name": "service_kube_node"},
        {"name": "os"}
    ]
}

Note

  • The version field is optional. When omitted, Omnia installs the default version bundled with the release.
  • Every functional_group_name must match an entry in the PXE mapping CSV (see Pxe Mapping File).
  • Kubernetes(service_k8s) cluster only supports x86_64 architecture.
  • Groups not listed in the JSON receive only base OS packages.
