Description

Add audit log collection and policy support for Kubernetes Event deletion (oc delete event).

Only DELETE operations on the events resource are forwarded — all other verbs (CREATE, UPDATE, PATCH, GET, WATCH, LIST) are filtered out. This lets users write audit log policies that detect tampering with API server events without generating noise from normal event lifecycle operations.

Changes:

  • Proto: Added EVENTS = 11 to KubernetesEvent.Object.Resource enum.
  • Collection filter: Added events to resourceTypesAllowList with a new verbsDenyListDeleteOnly that only allows DELETE through.
  • Event mapping: Added eventsEVENTS in auditResourceToKubeResource.
  • UI: Added Events option to the Kubernetes Resource selector in audit log policy criteria.
  • Tests: Added a dedicated test verifying only DELETE is forwarded for events, updated existing resource filter test.

Ref: RFE-6055

User-facing documentation

Testing and quality

  • the change is production ready: the change is GA, or otherwise the functionality is gated by a feature flag
  • CI results are inspected

Automated testing

  • added unit tests
  • added e2e tests
  • added regression tests
  • added compatibility tests
  • modified existing tests

How I validated my change

All audit log unit tests pass (go test ./compliance/collection/auditlog/...), including:

  • TestReaderOnlyForwardsDeleteVerbForEventsResource — verifies GET, WATCH, LIST, CREATE, UPDATE, PATCH are filtered and only DELETE passes.
  • TestReaderOnlySendsEventsThatMatchResourceTypeFilter — verifies the events resource is included in the allow-list with the correct verb.

📝 Summary

Summary by CodeRabbit

  • New Features
    • Added Kubernetes Events as a supported resource for audit log policies.
    • Event policies can target supported event actions, including deletion records.
    • Added Events to the Kubernetes resource selector.
    • Resource and verb choices are now limited to supported combinations.
    • Added validation messages for unsupported audit log resource and verb combinations.
    • Audit log processing now consistently recognizes supported resources and actions across policy configuration and event collection.

Walkthrough

Adds Kubernetes Events as an audit resource. The audit reader forwards only DELETE events, maps them to the Kubernetes event type, and validates compatible policy resource and verb combinations in the backend and UI.

Changes

Kubernetes events audit support

Layer / File(s) Summary
Audit resource and verb contracts
proto/storage/kube_event.proto, pkg/auditlog/auditlog.go, pkg/booleanpolicy/value_regex.go
Defines the EVENTS resource, shared resource mappings, allowed verbs, and derived deny lists.
Audit reader filtering and event mapping
compliance/collection/auditlog/...
Uses shared audit rules, maps events to KubernetesEvent_Object_EVENTS, forwards only DELETE records, and tests the behavior.
Backend policy compatibility validation
pkg/booleanpolicy/validate.go, pkg/booleanpolicy/validate_test.go
Rejects unsupported audit-log resource and verb combinations and tests supported and unsupported cases.
Policy editor compatibility controls
ui/apps/platform/src/Containers/Policies/Wizard/Step3/*
Adds Events to the resource selector, filters incompatible resource and verb choices, and validates selected combinations.

In
`@ui/apps/platform/src/Containers/Policies/Wizard/Step3/PolicyCriteriaFieldInput.tsx`:
- Around line 157-162: Normalize the resource key and verb values to uppercase
before the lookup and comparison in the allowed-verbs filtering logic. Update
the selectedResource access to use its uppercase form and compare each opt.value
using its uppercase form with allowedVerbs, preserving the existing
filteredOptions behavior.
- Around line 154-155: Update the counterpart-group option calculation around
selectedResource to evaluate every value in resourceGroup.values rather than
only values[0]. Derive permitted options using the intersection across all
counterpart resources, matching backend validation for each resource and verb
combination, and apply the same behavior to the corresponding logic around lines
169–170.

In
`@ui/apps/platform/src/Containers/Policies/Wizard/Step3/policyCriteriaValidators.ts`:
- Around line 70-76: Normalize each resource and verb to uppercase before the
validation lookups and comparisons in the policy criteria validator, including
the loops in validatePolicyCriteria. Also normalize selected values and option
values before filtering in PolicyCriteriaFieldInput.tsx at lines 157-175; update
both affected files so UI behavior matches the backend’s case-insensitive
handling.
