# StellaOps MongoDB & MinIO Cleanup Summary
|
||||
|
||||
**Date:** 2025-12-22
|
||||
**Executed By:** Development Agent
|
||||
**Status:** ✅ Immediate Actions Completed, Sprint Created for Remaining Work
|
||||
|
||||
---
|
||||
|
||||
## What Was Done Immediately
|
||||
|
||||
### 1. ✅ MongoDB Storage Shims Removed
|
||||
|
||||
**Deleted Directories:**
|
||||
- `src/Authority/StellaOps.Authority/StellaOps.Authority.Storage.Mongo`
|
||||
- `src/Notify/__Libraries/StellaOps.Notify.Storage.Mongo`
|
||||
- `src/Scheduler/__Libraries/StellaOps.Scheduler.Storage.Mongo`
|
||||
|
||||
**Reason:** These were empty build artifact directories with no source code. All services now use PostgreSQL storage exclusively.
|
||||
|
||||
### 2. ✅ Docker Compose Updated (dev.yaml)
|
||||
|
||||
**File:** `deploy/compose/docker-compose.dev.yaml`
|
||||
|
||||
**Changes:**
|
||||
- ❌ **Removed:** MongoDB service entirely
|
||||
- ❌ **Removed:** MinIO service entirely (RustFS is the primary storage)
|
||||
- ✅ **Added:** Valkey service (Redis-compatible, required for caching and DPoP security)
|
||||
- ✅ **Updated:** All services now use PostgreSQL connection strings
|
||||
- ✅ **Updated:** Cache references changed from Redis to Valkey
|
||||
- ✅ **Kept:** NATS (required for task queuing, not optional)
|
||||
- ✅ **Kept:** RustFS (primary object storage with web API)
|
||||
|
||||
**Infrastructure Stack (New):**
|
||||
```
|
||||
PostgreSQL 16 - Primary database (ALL services)
|
||||
Valkey 8.0 - Cache & DPoP nonce storage (REQUIRED)
|
||||
RustFS - Object storage with HTTP API (REQUIRED)
|
||||
NATS JetStream - Task queuing (REQUIRED)
|
||||
```
|
||||
|
||||
### 3. ✅ Environment Configuration Updated
|
||||
|
||||
**File:** `deploy/compose/env/dev.env.example`
|
||||
|
||||
**Removed Variables:**
|
||||
- `MONGO_INITDB_ROOT_USERNAME`
|
||||
- `MONGO_INITDB_ROOT_PASSWORD`
|
||||
- `MINIO_ROOT_USER`
|
||||
- `MINIO_ROOT_PASSWORD`
|
||||
- `MINIO_CONSOLE_PORT`
|
||||
|
||||
**Added Variables:**
|
||||
- `POSTGRES_USER`
|
||||
- `POSTGRES_PASSWORD`
|
||||
- `POSTGRES_DB`
|
||||
- `POSTGRES_PORT`
|
||||
- `VALKEY_PORT`
|
||||
|
||||
**Changed:**
|
||||
- `SCANNER_EVENTS_DRIVER` default changed from `redis` to `valkey`
|
||||
- All service configurations now point to PostgreSQL
|
||||
|
||||

|
||||
|
||||
## Investigation Findings
|
||||
|
||||
### MongoDB Usage (DEPRECATED - Removed)
|
||||
|
||||
**Discovery:**
|
||||
- MongoDB storage projects contained ONLY build artifacts (bin/obj directories)
|
||||
- NO actual source code (.cs files) existed
|
||||
- All services have PostgreSQL storage implementations
|
||||
- Docker compose had MongoDB configured but services were using PostgreSQL
|
||||
- Only legacy reference: Aoc.Cli had deprecated MongoDB verify option
|
||||
|
||||
**Conclusion:** MongoDB was already replaced by PostgreSQL, just needed config cleanup.
|
||||
|
||||
### MinIO vs RustFS (MinIO REMOVED)
|
||||
|
||||
**Discovery:**
|
||||
- MinIO was in docker-compose.dev.yaml with console on port 9001
|
||||
- NO .NET code references MinIO or AWS S3 SDK in any service
|
||||
- RustFS is the ACTUAL storage backend used in production
|
||||
- RustFS has HTTP API (S3-compatible protocol with custom headers)
|
||||
- MinIO was only for CI/testing, never used in real deployments
|
||||
|
||||
**Conclusion:** MinIO was cosmetic/legacy. RustFS is mandatory and primary.
|
||||
|
||||
### NATS vs Redis vs Valkey (ALL REQUIRED)
|
||||
|
||||
**Discovery:**
|
||||
- **NATS:** Production-required for task queuing (Scanner, Scheduler, Notify)
|
||||
- **Valkey:** Production-required for:
|
||||
- DPoP nonce storage (OAuth2 security - CRITICAL)
|
||||
- Distributed caching across 15+ services
|
||||
- Messaging transport option
|
||||
- **Redis:** StackExchange.Redis used everywhere, but Valkey is Redis-compatible drop-in
|
||||
|
||||
**Conclusion:** Both NATS and Valkey are REQUIRED, not optional. Valkey replaces Redis.
|
||||
|
||||
### CLI Situation (Needs Consolidation)
|
||||
|
||||
**Current State:**
|
||||
- **StellaOps.Cli** - Main CLI (complex, 40+ project dependencies)
|
||||
- **Aoc.Cli** - Single command (verify AOC compliance)
|
||||
- **Symbols.Ingestor.Cli** - Symbol extraction tool
|
||||
- **CryptoRu.Cli** - Regional crypto (GOST/SM) - KEEP SEPARATE
|
||||
|
||||
**Recommendation:**
|
||||
- Consolidate Aoc.Cli and Symbols.Ingestor.Cli into main stella CLI as plugins
|
||||
- Keep CryptoRu.Cli separate (regulatory isolation)
|
||||
|
||||

|
||||
|
||||
## Architecture Changes
|
||||
|
||||
### Before (Incorrect Documentation)
|
||||
```
|
||||
Infrastructure:
|
||||
- PostgreSQL ✅
|
||||
- MongoDB (optional) ❌ WRONG
|
||||
- MinIO (S3 storage) ❌ WRONG
|
||||
- NATS (optional) ❌ WRONG
|
||||
- Redis (optional) ❌ WRONG
|
||||
```
|
||||
|
||||
### After (Actual Reality)
|
||||
```
|
||||
Infrastructure:
|
||||
- PostgreSQL 16 ✅ REQUIRED (only database)
|
||||
- Valkey 8.0 ✅ REQUIRED (cache, DPoP security)
|
||||
- RustFS ✅ REQUIRED (object storage)
|
||||
- NATS JetStream ✅ REQUIRED (task queuing)
|
||||
```
|
||||

|
||||
|
||||
---
|
||||
|
||||
## Documentation Updates Needed
|
||||
|
||||
### Files Requiring Updates
|
||||
|
||||
1. **CLAUDE.md** - Remove MongoDB mentions, update infrastructure list
|
||||
2. **docs/07_HIGH_LEVEL_ARCHITECTURE.md** - Correct infrastructure section
|
||||
3. **docs/DEVELOPER_ONBOARDING.md** - Fix dependency info and architecture diagram
|
||||
4. **docs/QUICKSTART_HYBRID_DEBUG.md** - Remove MongoDB, update connection examples

||||
5. **deploy/README.md** - Update infrastructure description
|
||||
6. **deploy/compose/README.md** - Update compose profile documentation
|
||||
|
||||
### Key Corrections Needed
|
||||
|
||||
**Wrong Statement:**
|
||||
> "MongoDB (optional) - Advisory storage fallback"
|
||||
|
||||
**Correct Statement:**
|
||||
> "PostgreSQL 16+ is the ONLY supported database. All services use schema-isolated PostgreSQL storage."
|
||||
|
||||
**Wrong Statement:**
|
||||
> "NATS/Redis are optional transports"
|
||||
|
||||
**Correct Statement:**
|
||||
> "NATS JetStream is REQUIRED for task queuing. Valkey is REQUIRED for caching and OAuth2 DPoP security."
|
||||
|
||||
**Wrong Statement:**
|
||||
> "MinIO for object storage"
|
||||
|
||||
**Correct Statement:**
|
||||
> "RustFS is the primary object storage backend with HTTP S3-compatible API."
|
||||
|

|
||||
|
||||
## Breaking Changes
|
||||
|
||||
### For Developers
|
||||
|
||||
**If you had MongoDB in your .env:**
|
||||
```bash
|
||||
# Before (REMOVE THESE)
|
||||
MONGO_INITDB_ROOT_USERNAME=...
|
||||
MONGO_INITDB_ROOT_PASSWORD=...
|
||||
|
||||
# After (USE THESE)
|
||||
POSTGRES_USER=stellaops
|
||||
POSTGRES_PASSWORD=...
|
||||
POSTGRES_DB=stellaops_platform
|
||||
```
|
||||
|
||||
**If you used MinIO console:**
|
||||
- MinIO console is removed
|
||||
- Use RustFS HTTP API directly: `http://localhost:8080`
|
||||
- No web console needed (use API/CLI)
|
||||
|
||||
**If you used Aoc CLI with MongoDB:**
|
||||
```bash
|
||||
# Before (DEPRECATED)
|
||||
stella-aoc verify --mongo "mongodb://..."
|
||||
|
||||
# After (USE THIS)
|
||||
stella-aoc verify --postgres "Host=localhost;..."
|
||||
```
|
||||
|
||||
### For Operations
|
||||
|
||||
**Docker Volume Changes:**
|
||||
```bash
|
||||
# Old volumes (can be deleted)
|
||||
docker volume rm compose_mongo-data
|
||||
docker volume rm compose_minio-data
|
||||
|
||||
# New volumes (will be created)
|
||||
compose_postgres-data
|
||||
compose_valkey-data
|
||||
compose_rustfs-data
|
||||
```
|
||||
|
||||
**Port Changes:**
|
||||
```bash
|
||||
# Removed
|
||||
- 27017 (MongoDB)
|
||||
- 9001 (MinIO Console)
|
||||
|
||||
# Kept
|
||||
- 5432 (PostgreSQL)
|
||||
- 6379 (Valkey)
|
||||
- 8080 (RustFS)
|
||||
- 4222 (NATS)
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Migration Path
|
||||
|
||||
### For Existing Deployments
|
||||
|
||||
**Step 1: Backup MongoDB data (if any)**
|
||||
```bash
|
||||
docker compose exec mongo mongodump --out /backup
|
||||
docker cp compose_mongo_1:/backup ./mongodb-backup
|
||||
```
|
||||
|
||||
**Step 2: Update docker-compose and .env**
|
||||
```bash
|
||||
# Pull latest docker-compose.dev.yaml
|
||||
git pull origin main
|
||||
|
||||
# Update .env file (remove MongoDB, add PostgreSQL)
|
||||
cp deploy/compose/env/dev.env.example .env
|
||||
# Edit .env with your values
|
||||
```
|
||||
|
||||
**Step 3: Stop and remove old infrastructure**
|
||||
```bash
|
||||
docker compose down
|
||||
docker volume rm compose_mongo-data compose_minio-data
|
||||
```
|
||||
|
||||
**Step 4: Start new infrastructure**
|
||||
```bash
|
||||
docker compose up -d
|
||||
```
|
||||
|
||||
**Step 5: Verify services**
|
||||
```bash
|
||||
# Check all services connected to PostgreSQL
|
||||
docker compose logs | grep -i "postgres.*connected"
|
||||
|
||||
# Check no MongoDB connection attempts
|
||||
docker compose logs | grep -i "mongo" | grep -i "error"
|
||||
```
|
||||

|
||||
|
||||
## Testing Recommendations
|
||||
|
||||
### 1. Fresh Start Test
|
||||
```bash
|
||||
# Clean slate
|
||||
cd deploy/compose
|
||||
docker compose down -v
|
||||
|
||||
# Start with new config
|
||||
docker compose -f docker-compose.dev.yaml up -d
|
||||
|
||||
# Wait for services to be ready (2-3 minutes)
|
||||
docker compose ps
|
||||
|
||||
# Check logs for errors
|
||||
docker compose logs --tail=100 | grep -i error
|
||||
```
|
||||
|
||||
### 2. PostgreSQL Connection Test
|
||||
```bash
|
||||
# Connect to PostgreSQL
|
||||
docker compose exec postgres psql -U stellaops -d stellaops_platform
|
||||
|
||||
# List schemas (should see multiple per module)
|
||||
\dn
|
||||
|
||||
# List tables in a schema
|
||||
\dt scanner.*
|
||||
|
||||
# Exit
|
||||
\q
|
||||
```
|
||||
|
||||
### 3. Service Health Test
|
||||
```bash
|
||||
# Check each service
|
||||
for service in authority scanner-web concelier excititor; do
|
||||
echo "Testing $service..."
|
||||
docker compose logs $service | grep -i "started\|listening\|ready" | tail -5
|
||||
done
|
||||
```
|
||||
|
||||

||||
|
||||
📋 **Sprint created for remaining work:**
|
||||
- Update other docker-compose files
|
||||
- Clean up Aoc.Cli MongoDB references
|
||||
- Consolidate CLIs into single `stella` binary
|
||||
- Update all documentation
|
||||
