power-profile Specification

Categories:

Purpose

Keep the host’s selected power profile reproducible through its owning Ansible configuration while retaining an explicit desired profile.

Requirements

Requirement: Managed host power profile

The host’s Ansible configuration SHALL declare balanced as its desired Tuned profile. Deployment SHALL enable and start the existing Tuned service and persist the declared profile with manual selection. Deployment SHALL avoid reselecting an already-correct profile in manual mode and SHALL report unexpected profile-query failures.

Scenario: Selected profile differs

  • WHEN the active profile differs from the declared profile
  • THEN deployment selects and persists the declared profile

Scenario: Automatic selection is enabled

  • WHEN the active profile matches but selection is automatic
  • THEN deployment persists the declared profile with manual selection

Scenario: No profile is active

  • WHEN Tuned reports that no profile is active
  • THEN deployment selects the declared profile instead of failing on that expected query result

Scenario: Desired state already matches

  • WHEN the active profile matches and selection is manual
  • THEN deployment does not repeat the profile-selection command

Scenario: Query fails unexpectedly

  • WHEN querying the active profile or selection mode fails unexpectedly
  • THEN deployment reports the failure instead of concealing it
