generate-tuned-profile

Name

node-tuning:generate-tuned-profile

Synopsis

/node-tuning:generate-tuned-profile [profile-name] [--summary TEXT] [--include VALUE ...] [--sysctl KEY=VALUE ...] [--match-label KEY[=VALUE] ...] [options]

Description

The node-tuning:generate-tuned-profile command streamlines creation of tuned.openshift.io/v1 manifests for the OpenShift Node Tuning Operator. It captures the desired Tuned profile metadata, tuned daemon configuration blocks (e.g. [sysctl], [variables], [bootloader]), and recommendation rules, then invokes the helper script at plugins/node-tuning/skills/scripts/generate_tuned_profile.py to render a ready-to-apply YAML file.

Use this command whenever you need to:

• Bootstrap a new Tuned custom profile targeting selected nodes or machine config pools
• Generate manifests that can be version-controlled alongside other automation
• Iterate on sysctl, bootloader, or service parameters without hand-editing multi-line YAML

The generated manifest follows the structure expected by the cluster Node Tuning Operator:

apiVersion: tuned.openshift.io/v1
kind: Tuned
metadata:
  name: <profile-name>
  namespace: openshift-cluster-node-tuning-operator
spec:
  profile:
  - data: |
      [main]
      summary=...
      include=...
      ...
    name: <profile-name>
  recommend:
  - machineConfigLabels: {...}
    match:
    - label: ...
      value: ...
    priority: <priority>
    profile: <profile-name>

Implementation

1. Collect inputs
   • Confirm Python 3.8+ is available (python3 --version).
   • Gather the Tuned profile name, summary, optional include chain, sysctl values, variables, and any additional section lines (e.g. [bootloader], [service]).
   • Determine targeting rules: either --match-label entries (node labels) or --machine-config-label entries (MachineConfigPool selectors).
   • Decide whether an accompanying MachineConfigPool (MCP) workflow is required for kernel boot arguments (see Advanced Workflow below).
   • Use the helper's --list-nodes and --label-node flags when you need to inspect or label nodes prior to manifest generation.
