# Running Phoenix Integration Tests on GKE Cluster

This guide provides the exact commands to run the Phoenix integration tests on your GKE cluster.

## Current Status

✅ **Framework Complete**: All code implemented and tested locally
✅ **Documentation Complete**: Comprehensive testing guide created
✅ **Test Scripts Ready**: Automated test script available
⏸️  **Cluster Execution Pending**: Requires kubectl access with gke-gcloud-auth-plugin

## Prerequisites

Your GKE cluster configuration:
- **Cluster**: `gke_experio-staging_us-central1_c-hcylea0o7e9`
- **Region**: `us-central1`
- **Required**: `gke-gcloud-auth-plugin` installed

## Step 1: Install GKE Auth Plugin

If you don't have the auth plugin installed:

```bash
# Install gke-gcloud-auth-plugin
gcloud components install gke-gcloud-auth-plugin

# Or via brew (macOS)
brew install google-cloud-sdk
gcloud components install gke-gcloud-auth-plugin

# Verify installation
gke-gcloud-auth-plugin --version
```

## Step 2: Verify Cluster Access

```bash
# Check current context
kubectl config current-context
# Should show: gke_experio-staging_us-central1_c-hcylea0o7e9

# Verify connectivity
kubectl cluster-info

# Check namespaces
kubectl get namespaces | grep -E "observability|rem-app"
```

**Expected namespaces**:
- `observability` - For Phoenix and OTEL
- `rem-app` - For REM API

## Step 3: Check Phoenix Deployment

```bash
# Check Phoenix pods
kubectl get pods -n observability -l app=phoenix

# Check Phoenix service
kubectl get svc -n observability phoenix-svc

# Check Phoenix logs
kubectl logs -n observability deployment/phoenix --tail=50
```

**Expected output**:
```
NAME                       READY   STATUS    RESTARTS   AGE
phoenix-5d4f8b9c7d-abcde   1/1     Running   0          5d
```

If Phoenix is not deployed, you need to deploy it first. See Phoenix deployment docs.

## Step 4: Check REM API Deployment

```bash
# Check rem-api pods
kubectl get pods -n rem-app -l app=rem-api

# Check rem-api logs
kubectl logs -n rem-app deployment/rem-api --tail=50

# Verify API keys are configured
kubectl get secret -n rem-app rem-api-secrets
kubectl describe secret -n rem-app rem-api-secrets | grep -E "ANTHROPIC|OPENAI"
```

## Step 5: Set Up Local Environment

```bash
# Clone and enter REM repository
cd /path/to/rem

# Verify schemas exist
ls -la schemas/agents/examples/hello-world.yaml
ls -la schemas/evaluators/hello-world/default.yaml

# Set API keys (if not in cluster secrets)
export ANTHROPIC_API_KEY=<your-key>
# OR
export OPENAI_API_KEY=<your-key>
```

## Step 6: Run Automated Test (Port-Forward Mode)

This is the **recommended** approach for initial testing:

```bash
# Make test script executable
chmod +x .experiments/test-phoenix-integration.sh

# Run automated test with port-forward
./.experiments/test-phoenix-integration.sh port-forward
```

**What this does**:
1. ✅ Checks prerequisites (kubectl, schemas, API keys)
2. ✅ Sets up port-forward to cluster Phoenix (`kubectl port-forward -n observability svc/phoenix-svc 6006:6006`)
3. ✅ Creates test experiment (`hello-world-phoenix-test`)
4. ✅ Generates 5-example dataset
5. ✅ Runs dry-run validation
6. ✅ Executes full experiment with Phoenix
7. ✅ Verifies results (metrics.json, Phoenix UI)
8. ✅ Cleans up resources

**Expected output**:
```
================================================
Phoenix Integration Test - Mode: port-forward
================================================

==> Checking prerequisites
✓ In REM repository
✓ uv installed
✓ Agent schemas exist
✓ Evaluator schemas exist

==> Checking API keys
✓ ANTHROPIC_API_KEY set

==> Setting up port-forward to cluster Phoenix
✓ Phoenix service exists
✓ Port-forward running (PID: 12345)
✓ Phoenix URL: http://localhost:6006

==> Creating experiment: hello-world-phoenix-test
✓ Experiment created

==> Creating test dataset
✓ Dataset created (5 examples)

==> Verifying experiment configuration
Experiment: hello-world-phoenix-test
============================================================
...

==> Running dry-run test
✓ Loaded experiment: hello-world-phoenix-test
...
✓ Dry-run completed

==> Running experiment locally (with Phoenix)
✓ Loaded experiment: hello-world-phoenix-test

Phoenix Connection:
  URL: http://localhost:6006
  API Key: No

⏳ Running experiment: hello-world-phoenix-test-20250121-140000
   This may take several minutes...

✓ Experiment complete!
  View results: http://localhost:6006/experiments/<uuid>

✓ Saved metrics summary: .experiments/hello-world-phoenix-test/results/metrics.json

==> Verifying results
✓ Metrics file created

{
  "experiment_id": "<uuid>",
  "experiment_name": "hello-world-phoenix-test-20250121-140000",
  "agent": "hello-world",
  "evaluator": "default",
  "dataset_size": 5,
  "completed_at": "2025-01-21T14:00:00.000000",
  "phoenix_url": "http://localhost:6006/experiments/<uuid>",
  "task_runs": 5
}

✓ Open Phoenix UI: http://localhost:6006

==> Cleaning up
✓ Removed experiment directory
✓ Stopped port-forward (PID: 12345)

================================================
✓ All tests completed successfully!
================================================
```

## Step 7: Verify Phoenix UI

Open Phoenix UI to see results:

```bash
# Phoenix should be accessible at localhost:6006 (if port-forward is still running)
open http://localhost:6006

# Or restart port-forward if needed
kubectl port-forward -n observability svc/phoenix-svc 6006:6006
```

In Phoenix UI, verify:
1. Navigate to **Experiments** tab
2. Find experiment: `hello-world-phoenix-test-20250121-140000`
3. Check:
   - ✅ 5 task runs visible
   - ✅ Agent outputs captured
   - ✅ Evaluator scores present
   - ✅ LLM token usage tracked
   - ✅ Latency metrics recorded

## Step 8: Run On-Cluster Test (Production Mode)

After port-forward mode works, test cluster-native execution:

```bash
# Run test in cluster mode
./.experiments/test-phoenix-integration.sh cluster
```

**What this does**:
1. Creates ConfigMap with experiment config
2. Executes experiment from rem-api pod
3. Uses cluster DNS for Phoenix connection
4. Verifies results in Phoenix UI

**Expected output**:
```
================================================
Phoenix Integration Test - Mode: cluster
================================================

==> Setting up cluster execution
✓ rem-api deployment exists
✓ Phoenix URL: http://phoenix-svc.observability.svc.cluster.local:6006 (cluster DNS)

==> Creating experiment: hello-world-phoenix-test
✓ Experiment created

==> Creating test dataset
✓ Dataset created (5 examples)

==> Running experiment on cluster
✓ Experiment config copied to cluster
✓ Cluster execution completed

==> Verifying results
✓ Metrics file created
...

==> Cleaning up
✓ Removed experiment directory
✓ Removed cluster configmap

================================================
✓ All tests completed successfully!
================================================
```

## Step 9: Manual Verification (Optional)

For deeper inspection, run commands manually:

### Create Experiment

```bash
uv run rem experiments create hello-world-manual-test \
  --agent hello-world \
  --evaluator default \
  --description "Manual Phoenix integration test" \
  --tags "test,manual"
```

### Create Dataset

```bash
cat > .experiments/hello-world-manual-test/datasets/ground_truth.csv << 'EOF'
query,expected_greeting,difficulty
"Say hello","Hello!",easy
"Greet me","Hello!",easy
"Hi there","Hello!",easy
EOF
```

### Run Experiment with Port-Forward

```bash
# Terminal 1: Port-forward
kubectl port-forward -n observability svc/phoenix-svc 6006:6006

# Terminal 2: Run experiment
export PHOENIX_BASE_URL=http://localhost:6006
export ANTHROPIC_API_KEY=<your-key>

uv run rem experiments run hello-world-manual-test
```

### Run Experiment On-Cluster

```bash
# Copy experiment to cluster
kubectl create configmap hello-world-manual-test \
  --from-file=experiment.yaml=.experiments/hello-world-manual-test/experiment.yaml \
  --from-file=dataset.csv=.experiments/hello-world-manual-test/datasets/ground_truth.csv \
  -n rem-app

# Execute from rem-api pod
kubectl exec -it deployment/rem-api -n rem-app -- bash -c '
export PHOENIX_BASE_URL=http://phoenix-svc.observability.svc.cluster.local:6006
export PHOENIX_API_KEY=${PHOENIX_API_KEY}
export ANTHROPIC_API_KEY=${ANTHROPIC_API_KEY}

rem experiments run hello-world-manual-test
'
```

### View Results

```bash
# Check metrics
cat .experiments/hello-world-manual-test/results/metrics.json

# View Phoenix UI
open http://localhost:6006

# Check rem-api logs
kubectl logs -n rem-app deployment/rem-api --tail=100 | grep experiment
```

## Step 10: Test OTEL Integration

Verify OpenTelemetry traces are captured:

```bash
# Check OTEL collector
kubectl get pods -n observability -l app=otel-collector
kubectl logs -n observability deployment/otel-collector | grep rem

# Check if OTEL is enabled in rem-api
kubectl get deployment rem-api -n rem-app -o yaml | grep -A5 OTEL

# Run experiment (traces should be captured)
uv run rem experiments run hello-world-manual-test

# Verify traces in Phoenix UI
# Navigate to Traces tab, filter by project: rem-experiments
```

## Troubleshooting

### Issue: Cannot Connect to Cluster

```bash
# Verify gke-gcloud-auth-plugin is installed
which gke-gcloud-auth-plugin

# Reinstall if needed
gcloud components install gke-gcloud-auth-plugin

# Re-authenticate
gcloud auth login
gcloud container clusters get-credentials c-hcylea0o7e9 \
  --region us-central1 \
  --project experio-staging
```

### Issue: Phoenix Not Found

```bash
# Check if Phoenix is deployed
kubectl get all -n observability

# If not deployed, see Phoenix deployment documentation
# Or check if in different namespace:
kubectl get svc --all-namespaces | grep phoenix
```

### Issue: rem-api Not Found

```bash
# Check if rem-api is deployed
kubectl get all -n rem-app

# Check all namespaces
kubectl get deployment --all-namespaces | grep rem
```

### Issue: API Keys Not Set

```bash
# Check secrets
kubectl get secrets -n rem-app
kubectl describe secret rem-api-secrets -n rem-app

# If missing, create secret
kubectl create secret generic rem-api-secrets \
  --from-literal=ANTHROPIC_API_KEY=<your-key> \
  -n rem-app
```

### Issue: Port-Forward Fails

```bash
# Check if port 6006 is already in use
lsof -i :6006

# Kill existing process if needed
kill -9 $(lsof -t -i:6006)

# Try port-forward again
kubectl port-forward -n observability svc/phoenix-svc 6006:6006
```
