# BR-ORCH-043: Kubernetes Conditions for Orchestration Visibility

**Category**: Orchestration
**Priority**: P1 (High Value)
**Service**: RemediationOrchestrator
**Status**: ✅ **APPROVED** - V1.2 Implementation
**Created**: 2025-12-11
**Version**: 1.0

---

## 📋 **Business Requirement**

**Description**:
The RemediationOrchestrator service MUST implement Kubernetes Conditions to provide operators with comprehensive visibility into child CRD orchestration state through standard Kubernetes tooling.

**Rationale**:
As the **orchestration controller** for 4 child CRDs (SignalProcessing, AIAnalysis, RemediationApprovalRequest, WorkflowExecution), RemediationOrchestrator is the single point of truth for remediation lifecycle state. Without Conditions, operators must manually query 4 separate CRDs to understand remediation progress, significantly increasing Mean Time To Resolution (MTTR) and operational overhead.

**Business Value**:
- **80% Reduction in Diagnosis Time (MTTD)**: Operators see complete orchestration state from single `kubectl describe` command instead of querying 4 child CRDs
- **70% Reduction in Support Tickets**: Self-service troubleshooting via standard Kubernetes observability
- **Production Readiness**: Compliance with Kubernetes API conventions for professional operator experience
- **Automation Enablement**: Scripts can use `kubectl wait --for=condition=` for event-driven workflows

---

## 🎯 **Acceptance Criteria**

### **AC-043-1: Conditions Field in CRD Schema**

**Requirement**: RemediationRequest CRD MUST have `Conditions []metav1.Condition` field in status.

**Validation**:
```bash
kubectl explain remediationrequest.status.conditions
```

**Expected Output**: Field documentation for `conditions` with type `[]Condition`

---

### **AC-043-2: SignalProcessing Lifecycle Tracking**

**Requirement**: RO MUST set conditions tracking SignalProcessing CRD lifecycle.

**Conditions**:
1. **SignalProcessingReady**
   - **Status**: `True` when SP CRD created successfully
   - **Status**: `False` if SP CRD creation fails
   - **Reason Success**: `SignalProcessingCreated`
   - **Reason Failure**: `SignalProcessingCreationFailed`
   - **When**: Pending → Processing phase transition

2. **SignalProcessingComplete**
   - **Status**: `True` when SP transitions to `Completed` phase
   - **Status**: `False` if SP fails or times out
   - **Reason Success**: `SignalProcessingSucceeded`

---

### **AC-043-5: Overall Recovery Status** [Deprecated - Issue #180]

**Requirement**: RO MUST set condition tracking overall remediation outcome.

**Condition**: **RecoveryComplete** [Deprecated - Issue #180]
- **Status**: `True` when remediation reaches terminal phase (Completed/Failed)
- **Status**: `False` during active processing
- **Reason Success**: `RecoverySucceeded`
- **Reason Failure**: `RecoveryFailed`, `MaxAttemptsReached`, `BlockedByConsecutiveFailures`
- **When**: Terminal phase reached (including timeout and blocked-terminal paths; Issue #79 gap fix)

**Condition**: **Ready**
- **Status**: `True` when phase is Completed or Skipped
- **Status**: `False` when phase is Failed, TimedOut, or Cancelled

**Integration Point**: `pkg/remediationorchestrator/controller/reconciler.go` (phase transitions)

**Validation**:
```bash
# [Deprecated - Issue #180: RecoveryComplete removed]
kubectl wait --for=condition=RecoveryComplete remediationrequest <name> --timeout=10m
```

**Expected Output**: Command succeeds when remediation completes, providing automation support

---

### **AC-043-6: Kubernetes API Conventions Compliance**

**Requirement**: All conditions MUST follow Kubernetes API conventions.

**Standards**:
1. **Type**: CamelCase string (e.g., `SignalProcessingReady`)
2. **Status**: `True`, `False`, or `Unknown` (metav1.ConditionStatus)
3. **Reason**: CamelCase string explaining status (e.g., `AIAnalysisSucceeded`)
4. **Message**: Human-readable description with context
5. **LastTransitionTime**: Updated only when status changes
6. **ObservedGeneration**: Tracks which spec generation the condition reflects

**Reference**: [Kubernetes API Conventions - Typical Status Properties](https://github.com/kubernetes/community/blob/master/contributors/devel/sig-architecture/api-conventions.md#typical-status-properties)

**Validation**:
```bash
kubectl get remediationrequest <name> -o jsonpath='{.status.conditions[*].type}'
```

**Expected Output**: All 7 condition types present and correctly formatted

---

### **AC-043-7: Operator Automation Support**

**Requirement**: Conditions MUST support `kubectl wait` for automation.

**Test Cases**:
1. **Wait for Recovery** [Deprecated - Issue #180]:
   ```bash
   # [Deprecated - Issue #180: RecoveryComplete removed]
   kubectl wait --for=condition=RecoveryComplete rr/<name> --timeout=10m
   ```

2. **Wait for AI Analysis**:
   ```bash
   kubectl wait --for=condition=AIAnalysisComplete rr/<name> --timeout=5m
   ```

3. **Check Blocking State** [Deprecated - Issue #180]:
   ```bash
   # [Deprecated - Issue #180: RecoveryComplete removed]
   kubectl get rr/<name> -o jsonpath='{.status.conditions[?(@.type=="RecoveryComplete")].reason}'
   ```

**Expected Behavior**: Commands succeed when condition becomes `True`, timeout if exceeded

---

### **AC-043-8: Prometheus Metrics Integration**

**Requirement**: Conditions SHOULD be exposed as Prometheus metrics for alerting.

**Metrics** [Deprecated - Issue #180 for RecoveryComplete examples]:
```prometheus
# Condition state gauge [Deprecated - Issue #180: RecoveryComplete removed]
kube_customresource_condition{
  customresource="remediationrequest",
  condition="RecoveryComplete",
  status="true|false|unknown"
} 1

# Example alert rule [Deprecated - Issue #180]
- alert: RemediationBlockedForCooldown
  expr: |
    kube_customresource_condition{
      customresource="remediationrequest",
      condition="RecoveryComplete",
      status="false",
      reason="BlockedByConsecutiveFailures"
    } > 0
  annotations:
    summary: "RemediationRequest {{ $labels.name }} blocked by consecutive failures"
```

**Validation**: Query Prometheus for condition metrics after deployment

---

## 📊 **Business Impact Analysis**

### **Problem Statement**

**Current State** (No Conditions):
- Operators must query 4 separate CRDs to understand remediation state
- Average **diagnosis time**: **10-15 minutes** per incident (understanding what's happening)
- **40% of support tickets** are "how do I check remediation status?"
- No standard automation support for scripts/CI-CD

**Example Operator Workflow** (Current):
```bash
# Step 1: Check RemediationRequest phase
kubectl get remediationrequest rr-alert-123

# Step 2: Find SignalProcessing CRD (Issue #91: field selector replaces label)
kubectl get signalprocessing --field-selector spec.remediationRequestRef.name=rr-alert-123

# Step 3: Check SP status
kubectl describe signalprocessing sp-rr-alert-123

# Step 4: Find AIAnalysis CRD
kubectl get aianalysis --field-selector spec.remediationRequestRef.name=rr-alert-123

# Step 5: Check AI status
kubectl describe aianalysis ai-rr-alert-123

# Step 6: Find WorkflowExecution CRD
kubectl get workflowexecution --field-selector spec.remediationRequestRef.name=rr-alert-123

# Step 7: Check WE status
kubectl describe workflowexecution we-rr-alert-123

# Total time: 10-15 minutes per incident
```

### **Proposed Solution**

**With Conditions** (AC-043-1 through AC-043-7):
- **Single command** shows complete orchestration state
- Average **diagnosis time**: **2-3 minutes** per incident (80% reduction in MTTD)
- Self-service diagnosis reduces support tickets by 70%
- Standard automation via `kubectl wait`

**Example Operator Workflow** (With Conditions):
```bash
# Single command shows complete state
kubectl describe remediationrequest rr-alert-123

# Output shows all orchestration state:
Status:
  Overall Phase: Analyzing
  Conditions:
    Type:     SignalProcessingComplete
    Status:   True
    Reason:   SignalProcessingSucceeded
    Message:  SignalProcessing completed (env: production, priority: critical)

    Type:     AIAnalysisReady
    Status:   True
    Reason:   AIAnalysisCreated
    Message:  AIAnalysis CRD ai-rr-alert-123 created successfully

    Type:     AIAnalysisComplete
    Status:   False
    Reason:   InProgress
    Message:  Waiting for HolmesGPT investigation to complete

# Total time: 2-3 minutes per incident
```

### **Quantified Benefits**

| Metric | Current | With Conditions | Improvement |
|--------|---------|-----------------|-------------|
| **MTTD** (Diagnosis Time) | 10-15 min | 2-3 min | 80% reduction |
| **Commands for Diagnosis** | 4-7 commands | 1 command | 85% fewer |
| **Support Tickets** | 40% status-related | 12% status-related | 70% reduction |
| **Automation Support** | Manual scripting | `kubectl wait` | Standard tooling |
| **API Compliance** | Non-standard | Kubernetes conventions | Production-ready |

**Important Distinction**:
- **MTTD (Mean Time To Diagnose)**: ✅ Conditions reduce by 80% - faster understanding of "what's happening"
- **MTTR (Mean Time To Resolve)**: ⚠️ Conditions do NOT reduce - actual fix time unchanged

**What Conditions Help With**:
- ✅ **Diagnosis**: "Is AI analysis stuck?" → Check `AIAnalysisComplete` condition (instant answer)
- ✅ **Visibility**: "Which child CRD failed?" → See conditions in one place
- ✅ **Troubleshooting**: "Why is remediation blocked?" → `RecoveryComplete` reason explains [Deprecated - Issue #180]

**What Conditions DON'T Help With**:
- ❌ **Resolution Speed**: If workflow fails, Conditions won't make it succeed faster
- ❌ **Root Cause Fix**: Conditions show state, not how to fix underlying issues
- ❌ **Performance**: Conditions don't make remediation execute faster

## 🏗️ **Technical Implementation**

### **Phase 1: Infrastructure** (1.5 hours)

**Create**: `pkg/remediationorchestrator/conditions.go` (~150 lines)

**Contents**:
1. **7 Condition Type Constants**
2. **20+ Reason Constants** (success/failure/timeout for each condition)
3. **Helper Functions**:
   - `SetCondition(rr, conditionType, status, reason, message)`
   - `GetCondition(rr, conditionType)`
   - 7 type-specific setters (e.g., `SetSignalProcessingReady()`)

**Reference**: `pkg/aianalysis/conditions.go` (proven pattern)

---

### **Phase 2: CRD Schema** (15 minutes)

**Update**: `api/remediation/v1alpha1/remediationrequest_types.go`

**Add to RemediationRequestStatus**:
```go
// Conditions represent the latest available observations of orchestration state
// Per BR-ORCH-043: Track child CRD lifecycle for operator visibility
// +optional
// +patchMergeKey=type
// +patchStrategy=merge
// +listType=map
// +listMapKey=type
Conditions []metav1.Condition `json:"conditions,omitempty" patchStrategy:"merge" patchMergeKey:"type"`
```

**Regenerate**: `make manifests`

---

### **Phase 3: Controller Integration** (2-3 hours)

**Integration at 7 Orchestration Points**:

1. **SignalProcessing Creation** (Pending → Processing)
2. **SignalProcessing Completion** (Processing → Analyzing)
3. **AIAnalysis Creation** (Analyzing phase)
4. **AIAnalysis Completion** (Analyzing → AwaitingApproval/Executing)
5. **WorkflowExecution Creation** (Executing phase)
6. **WorkflowExecution Completion** (Executing → Verifying/Failed)
7. **Terminal Phase Transitions** (RecoveryComplete) [Deprecated - Issue #180]

**Pattern**:
```go
// After child CRD creation
sp, err := r.spCreator.Create(ctx, rr)
if err != nil {
    conditions.SetSignalProcessingReady(rr, false,
        conditions.ReasonSignalProcessingCreationFailed, err.Error())
    r.client.Status().Update(ctx, rr)
    return ctrl.Result{RequeueAfter: 5 * time.Second}, nil
}

conditions.SetSignalProcessingReady(rr, true,
    conditions.ReasonSignalProcessingCreated,
    fmt.Sprintf("SignalProcessing CRD %s created successfully", sp.Name))
```

---
