Chapter 17. Deploying distributed units manually on single-node OpenShift The procedures in this topic tell you how to manually deploy clusters on a small number of single nodes as a distributed unit (DU) during installation. The procedures do not describe how to install single-node OpenShift. This can be accomplished through many mechanisms. Rather, they are intended to capture the elements that should be configured as part of the installation process: Networking is needed to enable connectivity to the single-node OpenShift DU when the installation is complete. Workload partitioning, which can only be configured during installation. Additional items that help minimize the potential reboots post installation. 17.1. Configuring the distributed units (DUs) This section describes a set of configurations for an OpenShift Container Platform cluster so that it meets the feature and performance requirements necessary for running a distributed unit (DU) application. Some of this content must be applied during installation and other configurations can be applied post-install. After you have installed the single-node OpenShift DU, further configuration is needed to enable the platform to carry a DU workload. The configurations in this section are applied to the cluster after installation in order to configure the cluster for DU workloads. 17.1.1. Enabling workload partitioning A key feature to enable as part of a single-node OpenShift installation is workload partitioning. This limits the cores allowed to run platform services, maximizing the CPU core for application payloads. You must configure workload partitioning at cluster installation time. Note You can enable workload partitioning during cluster installation only. You cannot disable workload partitioning post-installation. However, you can reconfigure workload partitioning by updating the cpu value that you define in the performance profile, and in the related cpuset value in the MachineConfig custom resource (CR). Procedure The base64-encoded content below contains the CPU set that the management workloads are constrained to. This content must be adjusted to match the set specified in the performanceprofile and must be accurate for the number of cores on the cluster. apiVersion: machineconfiguration.openshift.io/v1 kind: MachineConfig metadata: labels: machineconfiguration.openshift.io/role: master name: 02-master-workload-partitioning spec: config: ignition: version: 3.2.0 storage: files: - contents: source: data:text/plain;charset=utf-8;base64,W2NyaW8ucnVudGltZS53b3JrbG9hZHMubWFuYWdlbWVudF0KYWN0aXZhdGlvbl9hbm5vdGF0aW9uID0gInRhcmdldC53b3JrbG9hZC5vcGVuc2hpZnQuaW8vbWFuYWdlbWVudCIKYW5ub3RhdGlvbl9wcmVmaXggPSAicmVzb3VyY2VzLndvcmtsb2FkLm9wZW5zaGlmdC5pbyIKW2NyaW8ucnVudGltZS53b3JrbG9hZHMubWFuYWdlbWVudC5yZXNvdXJjZXNdCmNwdXNoYXJlcyA9IDAKQ1BVcyA9ICIwLTEsIDUyLTUzIgo= mode: 420 overwrite: true path: /etc/crio/crio.conf.d/01-workload-partitioning user: name: root - contents: source: data:text/plain;charset=utf-8;base64,ewogICJtYW5hZ2VtZW50IjogewogICAgImNwdXNldCI6ICIwLTEsNTItNTMiCiAgfQp9Cg== mode: 420 overwrite: true path: /etc/kubernetes/openshift-workload-pinning user: name: root The contents of /etc/crio/crio.conf.d/01-workload-partitioning should look like this: [crio.runtime.workloads.management] activation_annotation = "target.workload.openshift.io/management" annotation_prefix = "resources.workload.openshift.io" [crio.runtime.workloads.management.resources] cpushares = 0 cpuset = "0-1, 52-53" 1 1 The cpuset value varies based on the installation. If Hyper-Threading is enabled, specify both threads for each core. The cpuset value must match the reserved CPUs that you define in the spec.cpu.reserved field in the performance profile. If Hyper-Threading is enabled, specify both threads of each core. The CPUs value must match the reserved CPU set specified in the performance profile.

Ensure all of the Hyper-Threading pairs match. 3 Set the reserved CPUs. When workload partitioning is enabled, system processes, kernel threads, and system container threads are restricted to these CPUs. All CPUs that are not isolated should be reserved. 4 Set the number of huge pages. 5 Set the huge page size. 6 Set node to the NUMA node where the hugepages are allocated. 7 Set userLevelNetworking to true to isolate the CPUs from networking interrupts. 8 Set enabled to true to install the real-time Linux kernel. 17.1.8.

Applying the distributed unit (DU) configuration to a single-node OpenShift cluster Perform the following tasks to configure a single-node cluster for a DU: Apply the required extra installation manifests at installation time. Apply the post-install configuration custom resources (CRs). 17.2.1. Applying the extra installation manifests To apply the distributed unit (DU) configuration to the single-node cluster, the following extra installation manifests need to be included during installation: Enable workload partitioning. Other MachineConfig objects - There is a set of MachineConfig custom resources (CRs) included by default. You can choose to include these additional MachineConfig CRs that are unique to their environment. It is recommended, but not required, to apply these CRs during installation in order to minimize the number of reboots that can occur during post-install configuration. 17.2.2.
