OCPBUGS-69681: limit ContainerRuntimeConfig status condition to 3

[aksjadha]

Fixes: https://redhat.atlassian.net/browse/OCPBUGS-69681

- What I did

The ContainerRuntimeConfig controller preserves all status conditions indefinitely instead of bounding the list. Over time this causes the conditions slice to grow unbounded (observed with 3313 Failure/Success conditions on a
single object), eventually triggering a gRPC ResourceExhausted error when updating status:

W1216 08:55:50.750828 1 container_runtime_config_controller.go:557] error updating container runtime config status: rpc error: code = ResourceExhausted desc = trying to send message larger than max (2526542 vs. 2097152)

This change trims newcfg.Status.Conditions in syncStatusOnly to keep only the most recent 3 entries whenever the list grows beyond that limit, preventing unbounded growth.

- How to verify it

1. Trigger repeated ContainerRuntimeConfig status updates (e.g. by causing the config to alternate between success and failure) so multiple conditions accumulate.
2. Check oc get containerruntimeconfig <name> -o json | jq '.status.conditions | length' and confirm it never exceeds 3, even after many sync cycles.

- Description for the changelog

Limit ContainerRuntimeConfig status conditions to the 3 most recent entries to prevent unbounded growth and ResourceExhausted errors.

Walkthrough

The controller now retains only the three newest ContainerRuntimeConfig status conditions and stores them in a new slice before persistence.

Layer / File(s)	Summary
Bound retained status conditions pkg/controller/container-runtime-config/container_runtime_config_controller.go	syncStatusOnly limits status conditions to the three newest entries and copies them into newly allocated storage.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to cea94

This change limits ContainerRuntimeConfig status conditions to the three most recent entries, preventing unbounded growth and oversized status updates; no actionable merge-blocking risk remains after normal checks and review.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 1 files.

Full details: Stable And Deterministic Test Names

Explanation

PASS: The pull request changes only pkg/controller/container-runtime-config/container_runtime_config_controller.go. The diff adds condition-list trimming in syncStatusOnly and adds no Ginkgo test files or test titles. Therefore, it introduces no unstable or dynamic test name.

Full details: Test Structure And Quality

Explanation

PASS. The commit changes only pkg/controller/container-runtime-config/container_runtime_config_controller.go (+10/-0) and changes no test files. The affected package contains standard testing tests, not Ginkgo It blocks, and no new cluster waits or test resource operations were introduced. Therefore this Ginkgo test-structure check is not applicable, and it introduces no explicit test-quality failure.

Full details: Microshift Test Compatibility

Explanation

PASS: The pull request changes only pkg/controller/container-runtime-config/container_runtime_config_controller.go. The diff adds condition-list trimming in syncStatusOnly and adds no Ginkgo e2e tests or other test declarations. Therefore, MicroShift test compatibility is not applicable.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

PASS: The pull request changes only pkg/controller/container-runtime-config/container_runtime_config_controller.go. The exact commit diff adds status-condition trimming logic and adds no It, Describe, Context, or When Ginkgo test. Therefore, the SNO multi-node test compatibility check is not applicable.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS — The pull request changes only syncStatusOnly in container_runtime_config_controller.go. The added code trims Status.Conditions and does not add or modify deployments, replicas, affinity, topology spread, node selectors, tolerations, or other scheduling constraints. The topology-aware scheduling check is therefore not triggered.

Full details: Ote Binary Stdout Contract

Explanation

PASS: The commit changes only syncStatusOnly in the controller. The 10 added lines allocate and copy a condition slice. They add no stdout writes, logging calls, or OTE suite setup changes. The OTE binary and its process-level code are unchanged. Existing klog calls in the controller are pre-existing and are not introduced by this pull request.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS: The pull request changes only pkg/controller/container-runtime-config/container_runtime_config_controller.go and adds no Ginkgo e2e tests. The IPv6 and disconnected-network test check is therefore not applicable.

Full details: No-Weak-Crypto

Explanation

The pull request adds only bounded ContainerRuntimeConfig condition-slice handling in syncStatusOnly. The added code contains no MD5, SHA1, DES, 3DES, RC4, Blowfish, or ECB usage, custom cryptography, or secret/token comparisons. The changed file also has no crypto imports or prohibited algorithm references.

Full details: Container-Privileges

Explanation

PASS: The pull request changes only pkg/controller/container-runtime-config/container_runtime_config_controller.go. The added code trims status conditions with a Go slice allocation and copy. The commit adds no container or Kubernetes manifest, and no added line contains privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, or allowPrivilegeEscalation.

Full details: No-Sensitive-Data-In-Logs

Explanation

PASS: The parent-to-HEAD diff adds only condition trimming in syncStatusOnly. It adds no logging statements and does not modify existing log arguments. The changed code copies the three newest conditions before UpdateStatus; it does not log passwords, tokens, API keys, PII, session IDs, internal hostnames, or customer data.

Add regression coverage for the retention limit.

Test four distinct status updates. Verify that exactly the newest three conditions remain. Also test a repeated status message to confirm that updating the latest condition does not increase the list length.
