The plugin is co-located with the Activity service it supports, making it easier to keep plugin updates in sync with service changes.

(status, scale) -- What fields change that users care about? - -### Step 2: Examine Existing Audit Logs - -``` -Use query_audit_logs to see actual audit events: -- filter: objectRef.resource == 'myresources' -- Look at verb, objectRef, user, responseObject -``` - -### Step 3: Design Rules - -Create rules for each meaningful operation: - -**CRUD Operations** -```yaml -auditRules: - - match: "audit.verb == 'create'" - summary: "{{ actor }} created {{ link(kind + ' ' + audit.objectRef.name, audit.responseObject) }}" - - - match: "audit.verb == 'delete'" - summary: "{{ actor }} deleted {{ kind }} {{ audit.objectRef.name }}" - - - match: "audit.verb in ['update', 'patch'] && audit.objectRef.subresource == ''" - summary: "{{ actor }} updated {{ link(kind + ' ' + audit.objectRef.name, audit.objectRef) }}" -``` - -**Status Updates (system-only)** -```yaml - - match: "audit.verb in ['update', 'patch'] && audit.objectRef.subresource == 'status'" - summary: "System updated status of {{ kind }} {{ audit.objectRef.name }}" -``` - -**Scale Operations** -```yaml - - match: "audit.objectRef.subresource == 'scale'" - summary: "{{ actor }} scaled {{ kind }} {{ audit.objectRef.name }}" -``` - -### Step 4: Design Event Rules - -For controller-generated events: - -```yaml -eventRules: - - match: "event.reason == 'Ready'" - summary: "{{ link(kind + ' ' + event.regarding.name, event.regarding) }} is now ready" - - - match: "event.reason == 'Failed'" - summary: "{{ kind }} {{ event.regarding.name }} failed: {{ event.note }}" - - - match: "event.type == 'Warning'" - summary: "Warning: {{ event.note }}" -``` - -### Step 5: Test with PolicyPreview - -```yaml -# Create test inputs -inputs: - - type: audit - audit: - verb: create - user: - username: alice@example.com - objectRef: - apiGroup: myservice.miloapis.com - resource: myresources - name: my-resource - namespace: default - responseStatus: - code: 201 - -# Preview will show: -# INPUT: audit create myresources/my-resource -# MATCHED: yes, rule 0 -# SUMMARY: alice@example.com created MyResource my-resource -``` - -## CEL Expression Reference - -### Match Expression Variables - -**Audit context:** -``` -audit.verb # create, update, delete, patch, get, list, watch -audit.objectRef.resource # plural resource name -audit.objectRef.name # resource name -audit.objectRef.namespace # namespace -audit.objectRef.apiGroup # API group -audit.objectRef.subresource # status, scale, or empty -audit.user.username # actor username -audit.responseStatus.code # HTTP status code -``` - -**Event context:** -``` -event.reason # Ready, Failed, Scheduled, etc. -event.type # Normal, Warning -event.note # Event message -event.regarding.name # Resource name -event.regarding.kind # Resource kind -event.regarding.namespace # Resource namespace -``` - -### Summary Template Variables - -``` -{{ actor }} # Human-readable actor name -{{ kind }} # Resource kind from spec -{{ audit.objectRef.name }} # Resource name -{{ audit.objectRef.namespace }} # Namespace -{{ event.note }} # Event message -``` - -### Helper Functions - -``` -{{ link(displayText, resourceRef) }} -# Creates a clickable link in UIs -# Example: {{ link(kind + ' ' + audit.objectRef.name, audit.responseObject) }} -# Renders as: "Domain example.com" (clickable) -``` - -## Best Practices - -### 1. Actor Detection - -The system automatically detects human vs system actors: -- Users: `alice@example.com` → human -- Service accounts: `system:serviceaccount:*` → system -- Controllers: `*-controller` → system - -Use `{{ actor }}` and the system handles this. - -### 2. Subresource Handling - -Always check for subresources to avoid duplicate summaries: -```yaml -# Spec updates (user-initiated) -- match: "audit.verb in ['update', 'patch'] && audit.objectRef.subresource == ''" - -# Status updates (controller-initiated) -- match: "audit.objectRef.subresource == 'status'" -``` - -### 3. Meaningful Summaries - -Good summaries are: -- **Action-oriented**: "created", "updated", "deleted", "scaled" -- **Resource-specific**: Include the resource name -- **Context-rich**: Include namespace when relevant -- **Linkable**: Use `link()` for clickable references - -### 4. Rule Ordering - -Rules are evaluated in order. Put specific rules first: -```yaml -# Specific first -- match: "audit.verb == 'delete' && audit.responseStatus.code == 404" - summary: "{{ actor }} attempted to delete non-existent {{ kind }}" - -# General fallback -- match: "audit.verb == 'delete'" - summary: "{{ actor }} deleted {{ kind }} {{ audit.objectRef.name }}" -``` - -## Example Policies - -### Simple CRUD Resource - -```yaml -apiVersion: activity.miloapis.com/v1alpha1 -kind: ActivityPolicy -metadata: - name: networking-domain -spec: - resource: - apiGroup: networking.datumapis.com - kind: Domain - auditRules: - - match: "audit.verb == 'create'" - summary: "{{ actor }} created {{ link(kind + ' ' + audit.objectRef.name, audit.responseObject) }}" - - match: "audit.verb == 'delete'" - summary: "{{ actor }} deleted {{ kind }} {{ audit.objectRef.name }}" - - match: "audit.verb in ['update', 'patch'] && audit.objectRef.subresource == ''" - summary: "{{ actor }} updated {{ link(kind + ' ' + audit.objectRef.name, audit.objectRef) }}" - - match: "audit.objectRef.subresource == 'status'" - summary: "System updated status of {{ kind }} {{ audit.objectRef.name }}" -``` - -### Workload with Scale - -```yaml -apiVersion: activity.miloapis.com/v1alpha1 -kind: ActivityPolicy -metadata: - name: compute-workload -spec: - resource: - apiGroup: compute.datumapis.com - kind: Workload - auditRules: - - match: "audit.objectRef.subresource == 'scale'" - summary: "{{ actor }} scaled {{ link(kind + ' ' + audit.objectRef.name, audit.objectRef) }}" - - match: "audit.verb == 'create'" - summary: "{{ actor }} created {{ link(kind + ' ' + audit.objectRef.name, audit.responseObject) }}" - - match: "audit.verb == 'delete'" - summary: "{{ actor }} deleted {{ kind }} {{ audit.objectRef.name }}" - - match: "audit.verb in ['update', 'patch'] && audit.objectRef.subresource == ''" - summary: "{{ actor }} updated {{ link(kind + ' ' + audit.objectRef.name, audit.objectRef) }}" - eventRules: - - match: "event.reason == 'Scaled'" - summary: "{{ kind }} {{ event.regarding.name }} scaled to {{ event.annotations['replicas'] }} replicas" - - match: "event.reason == 'Ready'" - summary: "{{ link(kind + ' ' + event.regarding.name, event.regarding) }} is now ready" - - match: "event.reason == 'Failed'" - summary: "{{ kind }} {{ event.regarding.name }} failed: {{ event.note }}" -``` - -## Workflow - -1. **Gather requirements**: What resource?

Order Rules Carefully - -Specific rules first, general fallbacks last: -```yaml -# Specific first -- match: "audit.verb == 'delete' && audit.responseStatus.code == 404" - summary: "{{ actor }} attempted to delete non-existent {{ kind }}" - -# General second -- match: "audit.verb == 'delete'" - summary: "{{ actor }} deleted {{ kind }} {{ audit.objectRef.name }}" -``` - -## Complete Example - -```yaml -apiVersion: activity.miloapis.com/v1alpha1 -kind: ActivityPolicy -metadata: - name: compute-workload -spec: - resource: - apiGroup: compute.datumapis.com - kind: Workload - auditRules: - - match: "audit.objectRef.subresource == 'scale'" - summary: "{{ actor }} scaled {{ link(kind + ' ' + audit.objectRef.name, audit.objectRef) }}" - - match: "audit.verb == 'create'" - summary: "{{ actor }} created {{ link(kind + ' ' + audit.objectRef.name, audit.responseObject) }}" - - match: "audit.verb == 'delete'" - summary: "{{ actor }} deleted {{ kind }} {{ audit.objectRef.name }}" - - match: "audit.verb in ['update', 'patch'] && audit.objectRef.subresource == ''" - summary: "{{ actor }} updated {{ link(kind + ' ' + audit.objectRef.name, audit.objectRef) }}" - - match: "audit.objectRef.subresource == 'status'" - summary: "System updated status of {{ kind }} {{ audit.objectRef.name }}" - eventRules: - - match: "event.reason == 'Ready'" - summary: "{{ link(kind + ' ' + event.regarding.name, event.regarding) }} is now ready" - - match: "event.reason == 'Scaled'" - summary: "{{ kind }} {{ event.regarding.name }} scaled to {{ event.annotations['replicas'] }} replicas" - - match: "event.type == 'Warning'" - summary: "Warning on {{ kind }} {{ event.regarding.name }}: {{ event.note }}" -```
