Add stale TO for repository update check job. read parameters from ConfigMap-backed config. - #291
Move the tunnable to configMap. provide a generic way to support it across Controllers
add a staleness timeout for repository dry run job during completed state to avoid too many jobs on BMC
Summary by CodeRabbit
New Features
Firmware-update settings can be supplied through a ConfigMap and updated while the service is running. Supported settings include retry limits, timing intervals, repository-pass limits, repository-check behavior, and scheduled-job timeouts.
Repository-pass limits and scheduled-job timeouts are configured through the ConfigMap rather than command-line options.
Bug Fixes
Periodic repository checks now wait for the configured interval before running again, while generation changes can trigger an immediate check.
Check progress and completion status are reported more consistently, and in-progress checks continue to respect their deadline.
The pull request adds a generic ConfigMap-backed loader and firmware-update configuration parsing and validation. Startup can register a firmware-update ConfigMap, and the reconciler reads settings through loader-backed accessors. Repository-check timing and status-condition handling also change.
Changes: ConfigMap configuration
Layer / File(s)
Summary
Generic loader and telemetry migration internal/configloader/loader.go, internal/telemetry/runtime/*
The generic loader watches ConfigMap additions and updates, parses configuration, and retains the last successfully loaded value after reload failures. The telemetry runtime now uses this loader.
Firmware-update configuration defines defaults and optional fields. Strict YAML parsing and validation check the API version and configured value bounds.
Startup and cache wiring cmd/main.go
Startup accepts a firmware-update ConfigMap name and namespace, resolves an omitted namespace from POD_NAMESPACE, and registers the loader when both values are set. Cache setup uses named ConfigMap references and name selectors where possible. The max-repository-passes and scheduled-job timeout flags are removed.
Reconciler configuration and repository-check handling internal/controller/system/firmwareupdate_controller.go, internal/controller/system/firmware_dell.go, internal/controller/system/firmwareupdate_controller_test.go, internal/controller/system/suite_test.go
The reconciler reads configurable values through loader-backed accessors. Repository checks use the configured interval, update in-progress and completion conditions, and preserve existing conditions when already completed. Tests set firmware-update settings through the loader.
ironcore-dev/metal-maintenance-operator#282: Adds progress-deadline processing for Pending and Completed FirmwareUpdates; this pull request changes deadline checks in those states.
The new periodic repository check for Completed firmware updates may never run, because nothing schedules a reconcile after a check is deferred. Return a requeue from the deferral branch before merging. Deployments that set the old FirmwareUpdate CLI flags will also silently fall back to defaults, so the ConfigMap migration should be documented.

Full details: Title check
Explanation
The title names two changes: a staleness timeout for the repository update check job, and reading parameters from ConfigMap-backed config. The changeset covers both. The raw summary shows a new generic configloader, a ConfigMap-backed FirmwareUpdate config, and Dell repository-check changes that add a completion-state staleness handling. The title is specific and lists the main changes, though it is long at 91 characters and uses the abbreviation 'TO' for timeout, which a reader may not parse at once.
Full details: Description check
Explanation
The description has two bullet points. They cover moving the tunable to a ConfigMap with a generic mechanism for controllers, and adding a staleness timeout for the repository dry-run job in the Completed state. The template's 'Fixes #' line is empty, and no issue number is given. The bullets do not explain the design, the new config keys, or the behavior change for existing deployments. The description is mostly complete for a PR of this size, but it is brief.
Resolution
Consider adding the issue number on the 'Fixes #' line if one exists. Consider also listing the new ConfigMap keys, their defaults, and the removed flags (max-repository-passes and the scheduled-job power-on timeout flag), because operators must update their deployments.

- Around line 565-572: Update the FirmwareUpdate configuration flow so the
values of --resync-interval, --default-failed-auto-retry-count, and
--min-bmc-reset-interval remain fallback defaults when the ConfigMap leaves
those fields unset; alternatively, document that these flags no longer configure
FirmwareUpdate and specify the ConfigMap migration path. Locate the wiring
around FirmwareUpdateReconciler and ConfigLoader.
Review comments at @internal/controller/system/firmware_dell.go:
- Around line 131-135: Update the repositoryCheckInterval age gate so it is
bypassed when ObservedGeneration differs from Generation, allowing specification
changes to proceed immediately; when a Completed update is intentionally
deferred by this gate, refresh its LastProgressTime. Keep the existing deadline
protection for periodic checks and do not exempt Completed updates from the
deadline.

Review comments at @internal/controller/system/firmware_dell.go:
- Line 140: Avoid calling r.Status().Patch on every firmware deferral when it
only updates the heartbeat timestamp; skip that patch unless meaningful status
changes. Preserve the configured resync interval and ensure actual firmware
status changes are still persisted.
- Line 139: In the Dell deferral path that updates LastProgressTime, preserve
the progress refresh but record completion in a separate timestamp set when the
update first enters Completed. Update FirmwareUpdateSet.handleTTL to use that
stable completion timestamp so periodic repository-check deferrals cannot reset
the TTL clock.

- Line 135: In the Completed-update handler, change the deferred
repository-check path so it requests a reconcile when repositoryCheckInterval
has not expired, either through the handler’s requeue signal or an explicit
delay for the remaining interval; preserve the existing behavior once the
interval has elapsed.

should we add at least a Kubernetes event and a metric for config_load_failures_total or similar? otherwise it is should a log and more difficult to understand for users
