Control** + - Only `SSOCloudDevGpuReservation` role allowed + - Configurable via environment variable + +3. ✅ **Time-Limited Keys** + - All API keys expire after 2 hours + - Forces frequent re-authentication + - Minimizes impact of leaked keys + +4. ✅ **No AWS Credentials Stored** + - API never stores AWS credentials + - Only uses them for verification + - Credentials discarded after verification + +5. ✅ **User Creation/Update** + - Atomic transaction (user + API key) + - Username extracted from AWS ARN + - User automatically created on first login + +### What's Protected Now + +- ✅ `/v1/jobs/submit` - Requires valid API key +- ✅ `/v1/jobs/{job_id}` - Requires valid API key +- ✅ `/v1/jobs` - Requires valid API key +- ✅ `/v1/keys/rotate` - Requires valid API key +- ✅

`api_keys.expires_at` - Stores expiration timestamp +- `api_keys.description` - Stores login source (AWS ARN) +- All other fields unchanged + +## 🚀 User Experience + +### Before (SQS) +```bash +#

-### 4. **Automatic Key Expiration** - -All API keys now have an expiration date: -- Default: 2 hours (configurable via `API_KEY_TTL_HOURS` env var) -- CLI can detect expiration and auto-refresh -- Old keys remain valid until they expire -

-2. ✅ **Role-Based Access Control** - - Only `SSOCloudDevGpuReservation` role allowed - - Configurable via environment variable - -3. ✅ **Time-Limited Keys** - - All API keys expire after 2 hours - - Forces frequent re-authentication - - Minimizes impact of leaked keys - -4. ✅ **No AWS Credentials Stored** - - API never stores AWS credentials - - Only uses them for verification - - Credentials discarded after verification - -5. ✅ **User Creation/Update** - - Atomic transaction (user + API key) - - Username extracted from AWS ARN - - User automatically created on first login - -### What's Protected Now - -- ✅ `/v1/jobs/submit` - Requires valid API key -- ✅ `/v1/jobs/{job_id}` -

Add aioboto3 - -**requirements.txt:** -``` -aioboto3==12.3.0 -``` - -**Code:** -```python -import aioboto3 - -async def verify_aws_credentials(...): - session = aioboto3.Session() - async with session.client( - 'sts', - aws_access_key_id=aws_access_key_id, - aws_secret_access_key=aws_secret_access_key, - aws_session_token=aws_session_token, - region_name=AWS_REGION - ) as sts_client: - identity = await sts_client.get_caller_identity() - return { - 'account': identity['Account'], - 'user_id': identity['UserId'], - 'arn': identity['Arn'] - } -``` - -### 2. Fix Role Matching - -```python -def extract_role_from_arn(arn: str) -> str: - """ - Extract role name from AWS ARN - arn:aws:sts::123:assumed-role/RoleName/username -> RoleName - """ - if ':assumed-role/' in arn: - # Split by '/' and get role name - parts = arn.split('/') - if len(parts) >= 2: - return parts[1] # Role name is second part - elif ':role/' in arn: - parts = arn.split('/') - if len(parts) >= 1: - return parts[-1] - return "" - -# In aws_login(): -role = extract_role_from_arn(identity['arn']) -if role != ALLOWED_AWS_ROLE: - raise HTTPException(403, f"Required role: {ALLOWED_AWS_ROLE}, got: {role}") -``` - -### 3. Add Logging - -```python -import logging -import sys - -# Configure at module level -logging.basicConfig( - stream=sys.stdout, - level=logging.INFO, - format='%(asctime)s - %(name)s - %(levelname)s - %(message)s' -) -logger = logging.getLogger(__name__) - -# Use throughout: -logger.info(f"Creating API key for user {username}") -logger.error(f"AWS auth failed", exc_info=True) -``` - -## ✅ What's Good - -1. ✅ **Good use of Pydantic for validation** -2. ✅ **Proper async/await throughout** -3. ✅ **Connection pooling implemented** -4. ✅ **Parameterized SQL queries (mostly)** -5. ✅ **API key hashing (SHA-256)** -6. ✅ **Timezone-aware datetimes** -7. ✅ **Transaction usage for atomic operations** -8. ✅ **Health check endpoint** -9. ✅ **Good code organization** -10. ✅ **Comprehensive error responses** - -## 🧪 Testing Checklist - -After fixes: - -- [ ] Test with invalid environment variables -- [ ] Test AWS authentication with various ARN formats -- [ ] Test with expired API keys -- [ ] Load test with concurrent requests -- [ ] Test connection pool under stress -- [ ] Test database schema creation on fresh DB -- [ ] Test error cases (DB down, AWS unreachable) -- [ ] Verify no blocking calls in async context - -## 📈 Performance Considerations - -Current bottlenecks: -1. **Boto3 blocking calls** - Main issue (100-300ms per call) -2. **DB connection acquisition** - Minor (1-5ms) -3. **API key hashing** - Negligible (<1ms) - -After fixing boto3 issue, expected improvement: -- 200-300ms → 50-100ms per AWS login (3-5x faster) - ---- - -## 🎓 Python Gotchas Found - -1. ✅ **Blocking I/O in async** - boto3 blocks event loop -2. ✅ **String matching security** - substring matching for security check -3. ✅ **Exception context loss** - missing `from e` -4. ✅ **Global mutable state** - `db_pool` (acceptable in this case) -5. ✅ **UPSERT return behavior** - may not always return expected value - ---- - -## 🚀 Next Steps - -1. **Immediate:** Fix critical issues (boto3, role matching) -2. **Short-term:** Add logging, rate limiting -3. **Medium-term:** Add job tracking, metrics -4. **Long-term:** Add comprehensive testing, CI/CD -

-#### 3. `POST /v1/auth/aws-login` -**Purpose:** Exchange AWS credentials for API key -**Security:** ✅ Protected -- Validates credentials with AWS STS -- Checks for required role (`SSOCloudDevGpuReservation`) -- Rate limiting recommended (not yet implemented) - -**Risk:** Medium without rate limiting -- Could be used for credential stuffing -- AWS will throttle STS calls - -**Action:** ✅ Keep - This is the main authentication endpoint -**TODO:** Add rate limiting before production - ---- - -### 🔐 Authenticated Endpoints (Require Valid API Key) - -#### 4. `POST /v1/jobs/submit` -**Purpose:** Submit GPU job to queue -**Security:** ✅ Protected -- Requires valid API key (2-hour expiration) -- User info extracted from token -- Input validation via Pydantic - -**Risk:** Low -- Users can only submit jobs for themselves -- No privilege escalation possible - -**Action:** ✅ Keep as-is - -#### 5. `GET /v1/jobs/{job_id}` -**Purpose:** Get job status -**Security:** ⚠️ Needs improvement -- Requires valid API key ✅ -- **Missing:** No check if job belongs to requesting user -- Any authenticated user can query any job ID - -**Risk:** Medium - Information disclosure -- Users can see other users' job status -- Job IDs are UUIDs (hard to guess but not impossible) - -**Action:** ⚠️ TODO - Add user ownership check: -```python -# Verify job belongs to user -job = await get_job_from_db(job_id) -if job['user_id'] != user['user_id']: -

-\* Medium risk without rate limiting - -### Security Strengths ✅ - -1. **AWS-Based Authentication** - - No password management - - Role verification required - - Credentials validated by AWS - -2. **Time-Limited Keys** - - 2-hour expiration - - Automatic refresh by CLI - - Reduces leaked key impact - -3. **Input Validation** - - Pydantic models validate all inputs - - Type checking enforced - - SQL injection prevented (parameterized queries) - -4. **No Admin Backdoors** - - `/admin/users` removed - - All users must authenticate via AWS - - No way to bypass authentication - -5. **Connection Security** - - Database connection pooling - - Prepared statements (asyncpg) - - No raw SQL concatenation - -### Security Gaps ⚠️ - -1. **No Rate Limiting** - - `/v1/auth/aws-login` could be abused - - Job submission could be spammed - - **Recommendation:** Add slowapi or similar - -2. **Job Ownership Not Verified** - - `/v1/jobs/{job_id}` doesn't check ownership - - Users can query other users' jobs - - **Recommendation:** Add ownership check - -3. **No Request Logging** - - Hard to detect abuse - - No audit trail - - **Recommendation:** Add structured logging - -4. **No Key Limits** - - Users can create unlimited keys - - Could fill database - - **Recommendation:** Limit to 10 active keys per user - -5. **No CORS Configuration** - - Not an issue if CLI-only - - Needed if web UI added - - **Recommendation:** Configure if needed - ---- - -## 🎯 Recommended Actions - -### High Priority (Before Production) - -1. **Add Job Ownership Check** ⚠️ - ```python - @app.get("/v1/jobs/{job_id}") - async def get_job_status(job_id: str, user: dict = Depends(verify_api_key)): - # TODO: Implement job tracking table - # job = await conn.fetchrow("SELECT * FROM jobs WHERE job_id = $1", job_id) - # if job['user_id'] != user['user_id']: - # raise HTTPException(403, "Access denied") - pass - ``` - -2. **Add Rate Limiting** - ```python - from slowapi import Limiter, _rate_limit_exceeded_handler - from slowapi.util import get_remote_address - - limiter = Limiter(key_func=get_remote_address) - app.state.limiter = limiter - - @app.post("/v1/auth/aws-login") - @limiter.limit("5/minute") # 5 logins per minute per IP - async def aws_login(...): - ... - ``` - -3. **Add Request Logging** - ```python - import logging - - @app.middleware("http") - async def log_requests(request: Request, call_next): - logger.info(f"{request.method} {request.url.path}", extra={ - "ip": request.client.host, - "user_agent": request.headers.get("user-agent") - }) - response = await call_next(request) - return response - ``` - -### Medium Priority - -4. **Implement Job Tracking** - - Create `jobs` table to track submissions - - Store job_id, user_id, status, timestamps - - Enable proper job status queries - -5. **Limit Active Keys Per User** - ```python - # Before creating new key - active_keys = await conn.fetchval(""" - SELECT COUNT(*) FROM api_keys - WHERE user_id = $1 AND is_active = true - AND (expires_at IS NULL OR expires_at > NOW()) - """, user_id) - - if active_keys >= 10: - raise HTTPException(429, "Too many active keys") - ``` - -6. **Add Metrics/Monitoring** - - Track auth failures - - Track job submissions per user - - Alert on anomalies - -### Low Priority (Nice to Have) - -7. **Add API Key Revocation Endpoint** - ```python - @app.delete("/v1/keys/{key_prefix}") - async def revoke_key(key_prefix: str, user: dict = Depends(verify_api_key)): - """Revoke a specific API key""" - await conn.execute(""" - UPDATE api_keys SET is_active = false - WHERE user_id = $1 AND key_prefix = $2 - """, user['user_id'], key_prefix) - ``` - -8. **Add Key Listing Endpoint** - ```python - @app.get("/v1/keys") - async def list_keys(user: dict = Depends(verify_api_key)): - """List all active keys for user""" - keys = await conn.fetch(""" - SELECT key_prefix, created_at, expires_at, last_used_at, description - FROM api_keys - WHERE user_id = $1 AND is_active = true - ORDER BY created_at DESC - """, user['user_id']) - return {"keys": [dict(k) for k in keys]} - ``` - ---- - -## 🧪 Security Testing Checklist - -Before deploying to production: - -- [ ] Test AWS authentication with invalid credentials -- [ ] Test AWS authentication with wrong role -- [ ] Test API key expiration (wait 2 hours or mock time) -- [ ] Test job submission with expired key -- [ ] Test job submission with invalid key -- [ ] Attempt to access another user's job (should fail after fix) -- [ ] Test rate limiting (once implemented) -- [ ] Verify all SQL queries use parameterization -- [ ] Run security scanner (bandit, safety) -- [ ] Review all error messages (no sensitive data leaked) -- [ ] Test HTTPS enforcement at ALB level -- [ ] Verify database credentials are from secrets - ---- - -## 📊 Risk Assessment - -### Overall Risk Level: **LOW-MEDIUM** ✅ - -**Justification:** -- Strong authentication (AWS-based) -- Time-limited keys (2 hours) -- No admin backdoors -- Input validation present -- Main gap: job ownership check (medium impact) -

-## 🚀 Overview - -This guide walks through deploying the GPU Dev API Service to your EKS cluster with public access via AWS Network Load Balancer. - -## 📋 What Gets Deployed - -``` -AWS Resources: -├── ECR Repository (gpu-dev-api-service) -├── IAM Role (IRSA for AWS STS access) -├── Network Load Balancer (internet-facing) -└── Target Groups (automatic) - -Kubernetes Resources: -├── ServiceAccount (with IRSA annotation) -├── ConfigMap (api-service-config) -├── Deployment (2 replicas) -├── Service (ClusterIP - internal) -└── Service (LoadBalancer - public) -``` - -## 🔧 Prerequisites - -Before deploying: - -1. ✅ **Postgres with PGMQ** - Already deployed (from previous steps) -2. ✅ **EKS Cluster** - Already configured -3. ✅ **AWS Load Balancer Controller** - Check if installed -4. ✅ **Docker** - For building image -5. ✅ **AWS CLI** - Configured with proper credentials - -### Check AWS Load Balancer Controller - -```bash -# Check if AWS Load Balancer Controller is installed -kubectl get deployment -n kube-system aws-load-balancer-controller - -# If not installed, install it: -# https://docs.aws.amazon.com/eks/latest/userguide/aws-load-balancer-controller.html -``` - -## 📦 Step 1: Build and Push Docker Image - -The Terraform configuration will automatically build and push the image, but you can do it manually: - -```bash -cd terraform-gpu-devservers/api-service - -# Get ECR repository URL -ECR_REPO=$(terraform output -raw api_service_ecr_url 2>/dev/null || \ - aws ecr describe-repositories --repository-names gpu-dev-api-service \ - --query 'repositories[0].repositoryUri' --output text) - -# Login to ECR -aws ecr get-login-password --region us-east-1 | \ - docker login --username AWS --password-stdin $ECR_REPO - -# Build image -docker build --platform linux/amd64 -t $ECR_REPO:latest . - -# Push image -docker push $ECR_REPO:latest - -echo "✅ Image pushed to $ECR_REPO:latest" -``` - -## 🚀 Step 2: Deploy to Kubernetes - -```bash -cd terraform-gpu-devservers - -# Plan the deployment -terraform plan - -# Apply (this will build image and deploy to K8s) -terraform apply - -# The build might take 2-5 minutes for first deployment -``` - -### What Terraform Does - -1. Creates ECR repository -2. Builds Docker image from `api-service/` -3. Pushes image to ECR -4. Creates IAM role with STS permissions -5. Creates Kubernetes ServiceAccount with IRSA -6. Creates ConfigMap with configuration -7. Deploys API service (2 replicas) -8. Creates LoadBalancer service -9. Provisions AWS NLB automatically - -## 🌐 Step 3: Get Public URL - -```bash -# Wait for LoadBalancer to be provisioned (1-3 minutes) -kubectl get svc -n gpu-controlplane api-service-public -w - -# Get the public URL -terraform output api_service_url - -# Or manually: -kubectl get svc -n gpu-controlplane api-service-public \ - -o jsonpath='{.status.loadBalancer.ingress[0].hostname}' - -# Example output: -# a1b2c3d4e5f6g7h8-123456789.us-east-1.elb.amazonaws.com -``` - -## ✅ Step 4: Verify Deployment - -### Check Pods - -```bash -# Check if pods are running -kubectl get pods -n gpu-controlplane -l app=api-service - -# Should show: -# NAME READY STATUS RESTARTS AGE -# api-service-xxxxxxxxxx-xxxxx 1/1 Running 0 2m -# api-service-xxxxxxxxxx-xxxxx 1/1 Running 0 2m -``` - -### Check Logs - -```bash -# View logs -kubectl logs -n gpu-controlplane -l app=api-service --tail=50 - -# Should see: -# INFO:app.main:Starting up API service... -# INFO:app.main:Database connection pool created -# INFO:app.main:Database schema initialized -# INFO:app.main:PGMQ queue 'gpu_reservations' created -# INFO:app.main:API service started successfully -``` - -### Test Health Check - -```bash -# Get LoadBalancer URL -LB_URL=$(terraform output -raw api_service_url | sed 's|http://||') - -# Test health endpoint -curl http://$LB_URL/health | jq . - -# Should return: -# { -# "status": "healthy", -# "database": "healthy", -# "queue": "healthy", -# "timestamp": "2026-01-15T..." -# } -``` - -### Test API Info - -```bash -# Test root endpoint -curl http://$LB_URL/ | jq . - -# Should return: -# { -# "service": "GPU Dev API", -# "version": "1.0.0", -# "docs": "/docs", -# "health": "/health", -# "auth": { -# "aws_login": "/v1/auth/aws-login", -# "description": "Use AWS credentials to obtain an API key" -# } -# } -``` - -### Test AWS Authentication - -```bash -# Get your AWS credentials -export AWS_ACCESS_KEY_ID=$(aws configure get aws_access_key_id) -export AWS_SECRET_ACCESS_KEY=$(aws configure get aws_secret_access_key) -export AWS_SESSION_TOKEN=$(aws configure get aws_session_token) - -# Test authentication -curl -X POST http://$LB_URL/v1/auth/aws-login \ - -H "Content-Type: application/json" \ - -d "{ - \"aws_access_key_id\": \"$AWS_ACCESS_KEY_ID\", - \"aws_secret_access_key\": \"$AWS_SECRET_ACCESS_KEY\", - \"aws_session_token\": \"$AWS_SESSION_TOKEN\" - }" | jq . - -# Should return API key with 2-hour expiration -``` - -### Browse API Documentation - -```bash -# Open Swagger UI in browser -echo "http://$LB_URL/docs" - -# Or ReDoc -echo "http://$LB_URL/redoc" -``` - -## 🔒 Step 5: Add HTTPS (Optional but Recommended) - -### Option A: Use AWS Certificate Manager (ACM) - -1. **Request certificate in ACM:** -```bash -# Create or import certificate -aws acm request-certificate \ - --domain-name api.gpudev.example.com \ - --validation-method DNS -``` - -2. **Update `api-service.tf`:** - -Uncomment the SSL annotations: -```hcl -annotations = { - # ... existing annotations ... - "service.beta.kubernetes.io/aws-load-balancer-ssl-cert" = "arn:aws:acm:us-east-1:123456789:certificate/xxx" - "service.beta.kubernetes.io/aws-load-balancer-ssl-ports" = "443" -} -``` - -Uncomment the HTTPS port: -```hcl -port { - name = "https" - port = 443 - target_port = 8000 - protocol = "TCP" -} -``` - -3. **Apply changes:** -```bash -terraform apply -``` - -4. **Create Route53 record:** -```bash -# Get LoadBalancer DNS -LB_DNS=$(kubectl get svc -n gpu-controlplane api-service-public \ - -o jsonpath='{.status.loadBalancer.ingress[0].hostname}') - -# Create CNAME record -aws route53 change-resource-record-sets \ - --hosted-zone-id ZXXXXXXXXXXXXX \ - --change-batch "{ - \"Changes\": [{ - \"Action\": \"UPSERT\", - \"ResourceRecordSet\": { - \"Name\": \"api.gpudev.example.com\", - \"Type\": \"CNAME\", - \"TTL\": 300, - \"ResourceRecords\": [{\"Value\": \"$LB_DNS\"}] - } - }] - }" -``` - -### Option B: Use AWS-provided DNS - -Just use the LoadBalancer DNS name directly: -```bash -# Get URL -terraform output api_service_url - -# Use as-is (no custom domain needed) -https://a1b2c3d4e5f6g7h8-123456789.us-east-1.elb.amazonaws.com -``` - -## 🔄 Step 6: Update CLI Configuration - -Update CLI to use the new API: - -```bash -# Set in CLI configuration or environment -export GPU_DEV_API_URL="http://$LB_URL" - -# Or for HTTPS: -export GPU_DEV_API_URL="https://api.gpudev.example.com" -``` - -## 📊 Monitoring - -### Check API Service Status - -```bash -# Pods -kubectl get pods -n gpu-controlplane -l app=api-service - -# Service -kubectl get svc -n gpu-controlplane api-service-public - -# Events -kubectl get events -n gpu-controlplane --field-selector involvedObject.name=api-service - -# Logs from all pods -kubectl logs -n gpu-controlplane -l app=api-service --all-containers=true --tail=100 -``` - -### Monitor Health - -```bash -# Continuous health monitoring -watch -n 5 'curl -s http://$LB_URL/health | jq .' - -# Check from within cluster -kubectl run -it --rm debug -n gpu-controlplane --image=curlimages/curl --restart=Never -- \ - curl http://api-service.gpu-controlplane.svc.cluster.local/health -``` - -## 🐛 Troubleshooting - -### Pods Not Starting - -```bash -# Check pod status -kubectl describe pod -n gpu-controlplane -l app=api-service - -# Check logs -kubectl logs -n gpu-controlplane -l app=api-service - -# Common issues: -# - Image pull error: Check ECR permissions -# - Database connection: Check postgres service is running -# - Config error: Check ConfigMap values -``` - -### LoadBalancer Not Provisioning - -```bash -# Check service events -kubectl describe svc -n gpu-controlplane api-service-public - -# Check AWS Load Balancer Controller logs -kubectl logs -n kube-system deployment/aws-load-balancer-controller - -# Common issues: -# - Controller not installed: Install AWS LB Controller -# - Insufficient permissions: Check IAM role for controller -# - Subnet tags missing: Ensure subnets have proper tags -``` - -### Health Check Failing - -```bash -# Test health from pod -kubectl exec -it -n gpu-controlplane deployment/api-service -- \ - curl localhost:8000/health - -# Check if postgres is reachable -kubectl exec -it -n gpu-controlplane deployment/api-service -- \ - curl postgres-primary:5432 -v - -# Check ConfigMap -kubectl get cm -n gpu-controlplane api-service-config -o yaml -``` - -### Authentication Not Working - -```bash -# Check if IAM role is properly annotated -kubectl get sa -n gpu-controlplane api-service-sa -o yaml | grep role-arn - -# Check IAM role permissions -aws iam get-role-policy \ - --role-name gpu-dev-api-service-role \ - --policy-name sts-get-caller-identity - -# Test from pod -kubectl exec -it -n gpu-controlplane deployment/api-service -- \ - python -c "import boto3; print(boto3.client('sts').get_caller_identity())" -``` - -## 🔄 Updating the Service - -### Update Code - -```bash -# Make changes to api-service/app/main.py - -# Terraform will detect changes and rebuild -terraform apply - -# Or force rebuild -terraform taint null_resource.api_service_build -terraform apply -``` - -### Scale Replicas - -```bash -# Edit api-service.tf -# Change: replicas = 2 -# To: replicas = 5 - -terraform apply - -# Or use kubectl -kubectl scale deployment -n gpu-controlplane api-service --replicas=5 -``` - -### Update Configuration - -```bash -# Edit ConfigMap values in api-service.tf -# Then apply: -terraform apply - -# Restart pods to pick up new config -kubectl rollout restart deployment -n gpu-controlplane api-service -``` - -## 🗑️ Cleanup - -### Remove API Service - -```bash -# Remove Kubernetes resources -terraform destroy -target=kubernetes_deployment.api_service -terraform destroy -target=kubernetes_service.api_service_public -terraform destroy -target=kubernetes_service.api_service - -# Remove ECR repository (optional) -terraform destroy -target=aws_ecr_repository.api_service -``` - -### Or use kubectl - -```bash -kubectl delete deployment -n gpu-controlplane api-service -kubectl delete svc -n gpu-controlplane api-service api-service-public -``` - -## 📈 Performance Tuning - -### Adjust Resources - -```hcl -# In api-service.tf, modify resources: -resources { - requests = { - cpu = "500m" # Increase for more performance - memory = "1Gi" # Increase if seeing OOM - } - limits = { - cpu = "2000m" - memory = "2Gi" - } -} -``` - -### Adjust Replicas - -```hcl -# In api-service.tf: -replicas = 5 # Scale up for higher load -``` - -### Enable Horizontal Pod Autoscaling (HPA) - -```bash -kubectl autoscale deployment api-service \ - -n gpu-controlplane \ - --cpu-percent=70 \ - --min=2 \ - --max=10 -``` - -## 🔐 Production Checklist - -Before going to production: - -- [ ] HTTPS enabled with ACM certificate -- [ ] Custom domain configured (or using AWS DNS) -- [ ] Rate limiting added to API code -- [ ] Request logging enabled -- [ ] Metrics/monitoring configured -- [ ] Alerts set up for errors -- [ ] Tested with real AWS credentials -- [ ] Load tested (100+ concurrent requests) -- [ ] CLI updated to use API URL -- [ ] Documentation updated for users -- [ ] Backup/DR plan in place -

Existing tables are not modified. + +**Q: Do I need to manually migrate data?** +A: No. The new SQL files create the exact same schema as the old Python code. + +**Q: Can I still use populate_gpu_types.py?** +A: It will still work, but it's no longer needed. GPU types are now populated via the fixture file during `tofu apply`. + +**Q: What if the migration job fails?** +A: The API won't start (by design). Check the job logs: `kubectl logs -n gpu-controlplane -l app=database-migration` + +**Q: Can I preview what SQL will be applied?** +A: Yes, just look at the files in `database/schema/` and `database/fixtures/`. They're plain SQL. + +**Q: How do I know the migration ran?** +A: Check for the migration job: `kubectl get jobs -n gpu-controlplane | grep db-migration` + +## Next Steps + +1. **Review the changes**: Look at the SQL files in `database/` +2. **Test in development**: Run `tofu plan` and `tofu apply` +3. **Verify migration**: Check job logs and table existence +4. **Update documentation**: Add any project-specific notes to `database/README.md` + +## Files Reference + +- **Schema files**: `terraform-gpu-devservers/database/schema/*.sql` +- **Fixture files**: `terraform-gpu-devservers/database/fixtures/*.sql` +- **Documentation**: `terraform-gpu-devservers/database/README.md` +- **Terraform config**: `terraform-gpu-devservers/kubernetes.tf` (lines 328+) +- **API verification**: `terraform-gpu-devservers/api-service/app/main.py` (lines 155-199) + diff --git a/terraform-gpu-devservers/database/README.md b/terraform-gpu-devservers/database/README.md new file mode 100644 index 00000000..89a62d5a --- /dev/null +++ b/terraform-gpu-devservers/database/README.md @@ -0,0 +1,313 @@ +# Database Schema Management + +This directory contains the database schema and fixture files for the GPU Dev platform.

Database Recreation Guide + +## ⚠️ IMPORTANT: This Project Uses OpenTofu (tofu), NOT Terraform + +**All commands in this guide use `tofu`, NEVER `terraform`.** + +See the [main README](reservation-processor-service/README.md) for detailed explanation of why this matters. + +## Overview + +This guide explains how to fully recreate the PostgreSQL database to ensure all columns from the schema files are properly created. + +## When to Use This + +Use database recreation when: +- ✅ Schema migrations are missing columns (like `disk_size`) +- ✅ You want a clean database with all schema definitions +- ✅ Database structure is inconsistent or corrupted +- ✅ Testing with a fresh state + +**⚠️ WARNING:** This is a **destructive operation** that will delete all existing data! + +## Three-Step Process + +### Step 1: Check Current Status + +First, see what you currently have and what will be deleted: + +```bash +./check-database-status.sh +``` + +This shows: +- Current PostgreSQL resources (StatefulSets, PVCs, Pods, Services) +- Table counts (reservations, disks, users, etc.) +- Schema info (checks if disk_size column exists) +- Active reservations +- What will be deleted + +### Step 2: Recreate Database + +Run the recreation script: + +```bash +./recreate-database.sh +``` + +**What it does:** + +1. **Backup Phase** (automatic) + - Creates backup directory: `./database-backups/YYYYMMDD-HHMMSS/` + - Exports full database dump: `full_backup.sql` + - Exports individual table CSVs: `reservations.csv`, `disks.csv`, etc. + +2. **Deletion Phase** + - Deletes schema migration job + - Deletes PostgreSQL StatefulSets (primary & replica) + - Deletes PostgreSQL Services + - **Deletes PVCs** (⚠️ ALL DATA DELETED) + +3. **Recreation Phase** + - Runs `tofu apply` to recreate resources + - Creates fresh PVCs with new EBS volumes + - Deploys new PostgreSQL StatefulSets + - Waits for pods to be ready + +4. **Schema Phase** + - Runs schema migration job + - Applies all schema files in order: + - `001_users_and_keys.sql` + - `002_reservations.sql` + - `003_disks.sql` (includes `disk_size` column!) + - `004_gpu_types.sql` + - `005_domain_mappings.sql` + - `006_alb_target_groups.sql` + - Applies fixture data + +5. **Verification Phase** + - Lists all tables + - Confirms `disk_size` column exists + - Checks PGMQ extension + +**Duration:** ~5-10 minutes + +### Step 3: Restore Data (Optional) + +If you want to restore from the backup: + +```bash +# List available backups +./restore-database-backup.sh + +# Restore from specific backup +./restore-database-backup.sh database-backups/20260121-183000/ +``` + +**Note:** Only restore if you need the old data.

Updated**: 2026-01-21 + +--- + +## Overview + +The Reservation Expiry Service is a Kubernetes CronJob that manages the lifecycle of GPU reservations by: + +- **Warning users** about expiring reservations at 30, 15, and 5 minutes before expiry +- **Expiring reservations** that have exceeded their time limit +- **Cleaning up pods and resources** for expired, failed, or cancelled reservations +- **Managing snapshots** for persistent disks during pod cleanup +- **Detecting stuck reservations** in preparing, queued, or pending states +- **Tracking OOM events** in running pods + +This service replaced the original Lambda function `lambda/reservation_expiry` as part of the DynamoDB → PostgreSQL migration. + +--- + +## Architecture + +### Execution Model + +- **Type**: Kubernetes CronJob +- **Schedule**: Every 5 minutes (`*/5 * * * *`) +- **Concurrency**: Forbid (no overlapping runs) +- **Timeout**: 10 minutes (`activeDeadlineSeconds: 600`) +- **Namespace**: `gpu-controlplane` + +### Key Components + +1. **Expiry Detection**: Scans active reservations and checks if they've exceeded their time limit +2. **Warning System**: Sends multi-level warnings to users via pod exec (creates files in `/home/dev`) +3. **Pod Cleanup**: Deletes pods, services, DNS records, and ALB mappings +4. **Snapshot Management**: Creates shutdown snapshots, syncs completed snapshots, cleans up old snapshots +5. **Stuck Reservation Handling**: Detects and fails/cancels reservations stuck in transient states +6. **OOM Detection**: Monitors pods for Out-of-Memory events and records them + +--- + +## Database Integration + +The service uses PostgreSQL instead of DynamoDB: + +- **Reservations**: `shared/reservation_db.py` for CRUD operations +- **Disks**: `shared/disk_db.py` for disk management +- **Connection Pooling**: `shared/db_pool.py` for efficient connections + +### Key Queries + +- `list_reservations_by_status(status, limit)` - Get reservations by status +- `update_reservation(reservation_id, updates)` - Update reservation fields +- `get_disk(user_id, disk_name)` - Get disk information +- `mark_disk_not_in_use(user_id, disk_name)` - Free up disk after pod deletion + +--- + +## Environment Variables + +### Required + +- `POSTGRES_HOST` - PostgreSQL host (injected by Terraform) +- `POSTGRES_PORT` - PostgreSQL port (default: 5432) +- `POSTGRES_USER` - PostgreSQL username +- `POSTGRES_PASSWORD` - PostgreSQL password (from secret) +- `POSTGRES_DB` - PostgreSQL database name +- `AWS_REGION` - AWS region +- `EKS_CLUSTER_NAME` - EKS cluster name for Kubernetes client + +### Optional + +- `WARNING_MINUTES` - Minutes before expiry to start warnings (default: 30) +- `GRACE_PERIOD_SECONDS` - Grace period after expiry before cleanup (default: 120) +- `AVAILABILITY_UPDATER_FUNCTION_NAME` - Lambda function to trigger after cleanup (optional) + +--- + +## IAM Permissions + +The service requires the following AWS permissions via IRSA: + +- **STS**: `GetCallerIdentity` (for Kubernetes client setup) +- **EKS**: `DescribeCluster` (for cluster access) +- **EC2**: Volume and snapshot management (create, delete, describe, tag) +- **Lambda**: `InvokeFunction` (for availability updater) +- **S3**: Read/write to disk contents bucket + +### Kubernetes RBAC + +The service has cluster-wide permissions for: + +- **Pods**: get, list, watch, delete (for cleanup) +- **Services**: get, list, watch, delete (for NodePort cleanup) +- **Events**: get, list, watch (for monitoring) +- **Nodes**: get, list, watch (for status checks) + +---

service account and RBAC: `kubectl get sa,clusterrole,clusterrolebinding -n gpu-controlplane | grep expiry` + +--- + +## Migration Notes + +### Changes from Lambda + +1. **Execution Model**: Lambda invocation → Kubernetes Job (batch execution) +2. **State Management**: DynamoDB → PostgreSQL +3. **Scheduling**: CloudWatch Events → Kubernetes CronJob +4. **Connection Management**: Lambda reused global clients → CronJob uses connection pooling + +### Key Code Changes + +1.

Kubernetes API** for actual GPU allocation and node status +- **Calculating availability metrics** including total GPUs, available GPUs, and max reservable +- **Supporting multinode reservations** for high-end GPUs (H100, H200, A100, B200) +- **Handling CPU-only nodes** with special user slot tracking +- **Updating PostgreSQL** with current availability data every 5 minutes + +This service replaced the original Lambda function `lambda/availability_updater` as part of the DynamoDB → PostgreSQL migration. + +--- + +## Architecture + +### Execution Model + +- **Type**: Kubernetes CronJob +- **Schedule**: Every 5 minutes (`*/5 * * * *`) +- **Concurrency**: Allow (updates are idempotent) +- **Timeout**: 5 minutes (`activeDeadlineSeconds: 300`) +- **Namespace**: `gpu-controlplane` + +### Key Components + +1. **ASG Query**: Scans all Auto Scaling Groups matching pattern `pytorch-gpu-dev-gpu-nodes-{gpu_type}*` +2. **Kubernetes Integration**: Queries node status and pod GPU requests via K8s API +3. **Multinode Support**: Calculates max reservable GPUs considering 4-node configurations +4. **CPU Node Handling**: Tracks user slots on CPU-only nodes (3 users per node) +5. **Database Updates**: Uses UPSERT to maintain current availability in PostgreSQL + +--- + +## Database Integration + +The service uses PostgreSQL instead of DynamoDB: + +- **GPU Types Table**: Updates

permissions missing +- **Fix**: Verify service account has correct IAM role annotation + +#### Database Connection Errors +- **Symptom**: "Failed to initialize connection pool" +- **Cause**: PostgreSQL not accessible or credentials incorrect +- **Fix**: + - Verify PostgreSQL is running: `kubectl get pods -n gpu-controlplane -l app=postgres` + - Check credentials secret: `kubectl get secret -n gpu-controlplane postgres-credentials` + - Test connectivity from within cluster + +#### Job Running Too Long +- **Symptom**: Job exceeds 5 minute timeout +- **Cause**: Large number of nodes or slow Kubernetes API +- **Fix**: Consider increasing `activeDeadlineSeconds` or optimizing queries + +### No Jobs Running + +- Check if CronJob is suspended: `kubectl get cronjob -n gpu-controlplane availability-updater -o yaml | grep suspend` +- Check schedule syntax: `kubectl describe cronjob -n gpu-controlplane availability-updater` +- Verify service account and RBAC: `kubectl get sa,clusterrole,clusterrolebinding -n gpu-controlplane | grep availability` + +--- + +## Migration Notes + +### Architectural Decision + +**Note**: The original migration plan proposed creating a separate `gpu_availability` table. However, the implementation adds availability columns directly to the existing `gpu_types` table. This approach: +- ✅ Reduces complexity (single table instead of two) +- ✅ Maintains data consistency (no JOIN required) +- ✅ Simplifies queries for the API service +- ✅ Groups static config with dynamic availability in one place + +### Changes from Lambda + +1. **Execution Model**: EventBridge trigger → Kubernetes CronJob (scheduled) +2. **State Management**: DynamoDB → PostgreSQL (availability data stored in `gpu_types` table) +3. **Scheduling**: CloudWatch Events → Kubernetes CronJob (every 5 minutes) +4. **Trigger Logic**: Event-driven (single GPU type) → Schedule-driven (all GPU types) +5. **Connection Management**: Lambda globals → CronJob connection pooling + +### Key Code Changes + +1. Replaced all `datetime.utcnow()` with `datetime.now(UTC)` +2. Replaced all `time.time()` with `datetime.now(UTC).timestamp()` +3. Replaced all DynamoDB calls with PostgreSQL queries via `availability_db.py` +4. Transformed Lambda `handler(event, context)` into `main()` function +5. Added connection pool init/cleanup in main() +6. Used shared utilities from `terraform-gpu-devservers/shared/` +7. Removed Lambda context dependencies (no `context.aws_request_id`) +8. Changed from event-driven to scheduled execution (scans all GPU types) + +### Bug Fixes + +- **Timezone Handling**: Fixed naive datetime usage (now uses `datetime.now(UTC)`) +- **Connection Pooling**: Added proper pool initialization and cleanup +- **Error Handling**: Improved error handling and logging +- **Kubernetes Client**: Added singleton pattern for K8s client reuse + +--- + +## Development + +### Local Testing + +```bash +# Build Docker image locally +cd terraform-gpu-devservers +docker build -f availability-updater-service/Dockerfile -t availability-updater:test . + +# Run with test environment variables (requires AWS credentials and K8s access) +docker run --rm \ + -e POSTGRES_HOST=localhost \ + -e POSTGRES_PASSWORD=test \ + -e AWS_REGION=us-east-2 \ + -e EKS_CLUSTER_NAME=pytorch-gpu-dev-cluster \ + -e AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID \ + -e AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY \ + -e AWS_SESSION_TOKEN=$AWS_SESSION_TOKEN \ + availability-updater:test +``` + +### Code Structure + +``` +availability-updater-service/ +├── Dockerfile # Container image definition +├── requirements.txt # Python dependencies +├── README.md # This file +└── updater/ + ├── __init__.py + └── main.py # Main updater logic +``` + +### Key Functions + +- `run_availability_update()` -

Implement SSO role authentication and provide setup instructions -- **Rename G6 to L4** - Update G6 references to L4 (similar to T4 GPU type naming) -- **Add network drive (EFS)** - Implement 20TB EFS shared storage mounted at /shared with user folders -- **GPU Profiling Support** - Added NVIDIA profiling capabilities for all pods: - - Node-level: Added `options nvidia NVreg_RestrictProfilingToAdminUsers=0` to `/etc/modprobe.d/nvprof.conf` in node bootstrap script - automatically configured on ALL new GPU nodes - - Bootstrap: Configuration added at `terraform-gpu-devservers/templates/al2023-user-data.sh:17-19` (applied BEFORE NVIDIA driver installation to avoid auto-load issue) - - Pod-level: Added Linux capability `SYS_ADMIN` to all GPU pods (required for NVIDIA profiling tools like ncu/nsys) -

- Fix: Changed to `CAP_SYS_ADMIN` which is required for NVIDIA GPU profiling (ncu, nsys) -- **Root Cause**: NVIDIA profiling tools need full SYS_ADMIN capability to access driver resources -- **Final Config**: `SYS_ADMIN` capability + node-level `NVreg_RestrictProfilingToAdminUsers=0` -- **Location**: Job Processor Pod configuration - -**No Persistent Disk Flag (Oct 8, 2025):** -- **Problem**: When user created 2nd reservation and confirmed "continue without persistent disk", job processor waited for disk detachment, timed out, set status to "failed", but then CONTINUED execution and restored from snapshot anyway -- **Root Cause 1**: The timeout logic raised exceptions caught by outer try-except blocks, but `persistent_volume_id` variable remained set from earlier operations -- **Root Cause 2**: Exception handler only set `use_persistent_disk = False` but didn't clear `persistent_volume_id` -- **Fix Part 1 - Explicit Flag**: Added `no_persistent_disk` flag that flows from CLI through API/PGMQ to Job Processor - - CLI: When user confirms to continue without persistent disk, sets `no_persistent_disk=True` in API request -

Create `/shared-personal//startup.sh` -2. On your next reservation, the script will run automatically -3. Check `/home/dev/startup-output.log` for execution output - -**Example startup.sh:** -```bash -#!/bin/bash -# Install additional packages -pip install my-favorite-package - -# Clone a repo -git clone https://github.com/myuser/myrepo /workspace/myrepo -
