Walkthrough

The termination watcher now defaults to a 240-second graceful termination period. Timeout checks, delayed lock-file cleanup, and timeout event reporting use the corrected duration variable.

Changes

Graceful termination timeout

Layer / File(s) Summary
Timeout duration and cleanup handling
cmd/watch-termination/main.go
The default graceful termination period changes from 105 to 240 seconds. Timeout thresholds, delayed lock-file cleanup, and timeout event messages use the corrected gracefulTerminationPeriod variable.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: 🟡 Moderate · up to e7ff1

The default graceful-termination timeout increases to 240 seconds, while the CLI help still shows a stale 105s example. The behavior change has no supplied correctness or availability concern, but this PR is still marked work in progress and is not merge-ready until that status is cleared and the help text is corrected.

Single Node Openshift (Sno) Test Compatibility ✅ Passed The PR changes only cmd/watch-termination/main.go and adds no Ginkgo e2e tests, so the SNO compatibility check is not applicable.

No-Weak-Crypto ✅ Passed The only changed file updates a termination timeout from 105s to 240s and renames its variable; no weak-crypto APIs, algorithms, or secret comparisons were added.
Container-Privileges ✅ Passed The commit changes only Go timeout logic in cmd/watch-termination/main.go; it adds no container or Kubernetes manifest privilege settings.
No-Sensitive-Data-In-Logs ✅ Passed The diff only changes the timeout value and variable references; it adds no logging calls or sensitive data such as credentials, PII, hostnames, or customer data.

Update the stale duration example.

The flag now defaults to 240*time.Second, but its help text still says e.g. 105s. Update the example to 240s or use a neutral example such as 4m.
