TL;DR

Fixes nvcf-cli cluster agent kill-all/kill-function reporting [deleted] and exiting 0 for ICMSRequests that are still stuck Terminating behind a finalizer, so operators no longer get a false success signal while the underlying function pod keeps running.

Additional Details (optional for docs, build, test, refactor, ci, chore, style, and revert PRs)

deleteICMSRequest in internal/clusteragent/k8s_maintainer.go called Kubernetes Delete() on an ICMSRequest and treated a nil error (including NotFound) as "deleted." But Delete() only guarantees the deletion was accepted — when the object carries the nvca.finalizers.nvidia.io finalizer (set by the NVCA reconciler), the API server just stamps deletionTimestamp and the object, and the pod it owns, stay alive until NVCA finishes evicting the workload and removes the finalizer itself. If NVCA is slow, stuck, or down, that never happens, but the CLI had already printed [deleted] and exited 0.

deleteICMSRequest now polls Get after Delete until the object actually disappears or a bounded --timeout (default 60s, new clusteragent.DefaultKillTimeout) elapses. KilledRequest gained a Terminating field and KillResult a TerminatingCount: a request still present at the deadline is reported as terminating, not deleted, is excluded from the success count, and makes the command return a non-zero-exit aggregate error instead of silently succeeding. The happy path (object disappears quickly) still reports deleted as before.

While investigating, I traced the NVCA reconciler's deletion-handling code and confirmed that deleting the CR does not itself trigger pod eviction — the reconciler's deletion branch only checks AllInstancesTerminatedAndReported and removes the finalizer if true, deferring to the normal ICMS-driven termination-message flow for actual teardown. That's a separate, deeper design question worth the team's attention (whether non---force kill-all reliably terminates a healthy-but-hung function at all) but out of scope here; this PR's fix is specifically about the CLI no longer lying about the outcome.

For the Reviewer

Core change is in internal/clusteragent/k8s_maintainer.go (deleteICMSRequest, new waitForICMSRequestGone, killMatching, aggregateKillError) and the type additions in internal/clusteragent/maintainer.go (KillOptions.Timeout, KilledRequest.Terminating, KillResult.TerminatingCount, DefaultKillTimeout). CLI wiring (--timeout flag, printKillResult status label) is in cmd/cluster_agent_maintenance.go.

For QA (optional for docs, build, test, refactor, ci, chore, style, and revert PRs)

  • New unit tests in internal/clusteragent/k8s_maintainer_test.go: TestKillReportsTerminatingWhenFinalizerBlocksDeletion (uses a delete reactor to simulate a finalizer-blocked object surviving Delete, since the fake dynamic client's tracker doesn't emulate real finalizer semantics) and TestKillWithinTimeoutReportsDeletedNotTerminating (confirms the fast/normal path still reports plain deleted). Both fail against the pre-fix code and pass against the fix.
  • go build ./... and go test ./internal/clusteragent/... ./cmd/... pass.
  • Verified live against a local self-managed k3d cluster: hand-created an ICMSRequest with the real finalizer (no backing pod, so NVCA never removes it, exactly reproducing a stuck-NVCA scenario); pre-fix binary printed [deleted]/exit 0 while the object remained Terminating; fixed binary correctly printed [terminating: ...], left it undeleted, and exited non-zero after waiting out --timeout.

Summary by CodeRabbit

  • New Features

    • Added configurable timeouts for function and cluster-wide termination commands.
    • Termination results now distinguish successfully deleted requests from requests still terminating.
    • Added aggregate reporting for requests that remain in a terminating state.
  • Bug Fixes

    • Deletion now waits for resources to disappear and applies a default timeout.
    • Forced deletion continues to handle blocking finalizers appropriately.

Review Change Stack

📝 Walkthrough

Walkthrough

Kill commands now accept a configurable deletion timeout. ICMSRequest deletion waits for resource removal and reports requests that remain terminating. CLI output separates completed, failed, and terminating requests.

Changes

Kill termination handling

Layer / File(s) Summary
Kill timeout and result contracts
src/clis/nvcf-cli/internal/clusteragent/maintainer.go
Defines the default timeout and adds timeout and terminating-status fields to kill options and results.
Deletion wait and aggregation
src/clis/nvcf-cli/internal/clusteragent/k8s_maintainer.go, src/clis/nvcf-cli/internal/clusteragent/k8s_maintainer_test.go
Waits for ICMSRequests to disappear after deletion, reports timeout-based terminating status, preserves deletion failures, and tests both blocked and completed deletion.
CLI timeout wiring and result output
src/clis/nvcf-cli/cmd/cluster_agent_maintenance.go
Passes the configured timeout for function and cluster-wide kills and renders terminating requests separately from completed deletions.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 373c3

The change improves kill command reporting, but the current implementation can exceed the configured timeout and can hide the underlying reason a deletion failed; negative timeout values are also accepted and silently replaced with the default. These bounded behavior issues should be fixed or explicitly accepted before merging.

Add command-level coverage for kill timeout and output.

The tests do not assert --timeout forwarding for either kill-function or kill-all. They only assert failed output and dry-run call behavior. Add assertions for deleted, failed, terminating, dry-run, and JSON output.

- Around line 454-471: The deletion polling loop should enforce the configured
deadline in the resource-check flow: bound each Get call and sleep interval by
the deletion deadline, while preserving true,nil on deletion timeout and
ctx.Err() on caller cancellation. Update the relevant maintainer method and add
a regression test covering a poll interval longer than Timeout.
- Around line 400-402: Update the kill-operation error handling around
aggregateKillError so original failures are retained outside the JSON result,

or join each underlying error when constructing the returned aggregate error so
callers can use errors.Is and errors.As, and add regression coverage for

- Around line 381-384: Update the timeout validation in killMatching so negative
opts.Timeout values return an error, while zero continues to select
DefaultKillTimeout. Add a regression test covering a negative --timeout value
and verify the existing default behavior for zero remains unchanged.

In `@src/clis/nvcf-cli/internal/clusteragent/maintainer.go`:
- Around line 117-121: Update the KilledRequest.Error documentation near the
deletion outcome comments to state that it may contain failures from delete,
stripFinalizers, or waitForICMSRequestGone, or otherwise describe it broadly as
a failed deletion operation; keep the comment concise and limited to this
non-obvious contract.

Reject negative --timeout values.

--timeout=-1s is accepted as a negative duration, but killMatching maps all values <= 0 to DefaultKillTimeout. Return an error for negative values and keep zero as the default. Add a regression test.

Enforce the configured deletion timeout.

When Timeout is shorter than killDeletionPollInterval, the loop can sleep for the full poll interval before reporting Terminating. A blocked Get can also exceed Timeout because it uses the parent context. Bound both polling and Get by the deletion deadline, while preserving (true, nil) for deletion timeout and ctx.Err() for caller cancellation. Add a regression test with a poll interval greater than Timeout.

Correct the Error contract.

KilledRequest.Error can contain errors from stripFinalizers and waitForICMSRequestGone, not only errors from Delete. Describe it as a failed deletion operation, or name every operation that can set it.

As per path instructions, keep comments self-documenting and limited to non-obvious logic.
