+# MongoDB Health Check Troubleshooting
+
+## Problem
+MongoDB container failing health checks despite running properly.
+
+## Root Cause Analysis
+
+### Issue 1: Complex Healthcheck Command
+The original healthcheck used shell script format which can be problematic:
+```yaml
+test: |
+  mongosh --eval "db.adminCommand('ping').ok" --quiet
+```
+
+### Issue 2: Insufficient Startup Time
+Even with 40s start_period, MongoDB may need more time on:
+- First run (data initialization)
+- Slower systems
+- Systems with high I/O wait
+
+### Issue 3: Log Format Issues
+The logs show extreme verbosity and duplication, suggesting the container is outputting logs in an unusual format.
+
+## Solution: Simplified Healthcheck
+
+### Updated Configuration
+```yaml
+healthcheck:
+  test: echo 'db.runCommand("ping").ok' | mongosh localhost:27017/test --quiet
+  interval: 10s
+  timeout: 5s
+  retries: 5
+  start_period: 60s  # Increased from 40s to 60s
+```
+
+### Key Changes
+1. **Piped command instead of --eval**: More reliable with mongosh
+2. **Explicit localhost**: Avoids DNS resolution issues
+3. **Simple test database**: Uses /test instead of admin
+4. **Longer start_period**: 60s gives MongoDB plenty of time
+
+## Alternative: Disable Healthcheck for Development
+
+If healthchecks continue to cause issues, you can disable them for development:
+
+```yaml
+healthcheck:
+  disable: true
+```
+
+Or remove the healthcheck entirely and use a simple dependency:
+
+```yaml
+depends_on:
+  - mongodb
+  # Remove: condition: service_healthy
+```
+
+## How to Apply
+
+### Option 1: Pull and Restart (Recommended)
+```bash
+git pull origin main
+docker compose -f docker-compose.dev.yml down -v
+docker compose -f docker-compose.dev.yml up -d
+docker compose -f docker-compose.dev.yml logs -f mongodb
+```
+
+### Option 2: Disable Healthcheck (Quick Fix)
+Edit `docker-compose.dev.yml` and replace the healthcheck section with:
+```yaml
+healthcheck:
+  disable: true
+```
+
+Then restart:
+```bash
+docker compose -f docker-compose.dev.yml down -v
+docker compose -f docker-compose.dev.yml up -d
+```
+
+## Verification
+
+### Check Container Status
+```bash
+docker ps --format "table {{.Names}}	{{.Status}}"
+```
+
+### Check MongoDB Connection
+```bash
+docker exec normogen-mongodb-dev mongosh --eval "db.adminCommand('ping')"
+```
+
+### Check Health Status
+```bash
+docker inspect normogen-mongodb-dev --format='{{json .State.Health}}' | jq
+```
+
+## Common Issues and Fixes
+
+### Issue: Port Already in Use
+```bash
+# Check what's using port 27017
+sudo lsof -i :27017
+
+# Kill the process if needed
+sudo kill -9 <PID>
+```
+
+### Issue: Corrupted Volume
+```bash
+# Remove the volume and start fresh
+docker compose -f docker-compose.dev.yml down -v
+docker compose -f docker-compose.dev.yml up -d
+```
+
+### Issue: mongosh Not Found
+This shouldn't happen with mongo:6.0, but if it does:
+```bash
+# Verify mongosh exists
+docker exec normogen-mongodb-dev which mongosh
+
+# If not found, try using mongo (legacy)
+docker exec normogen-mongodb-dev which mongo
+```
+
+## Development vs Production
+
+### Development (Current)
+- Healthcheck enabled but with generous timeouts
+- Focus on getting up and running quickly
+- Can disable healthcheck if causing issues
+
+### Production
+- Healthcheck is critical
+- Must use proper healthcheck with monitoring
+- Consider using orchestration tools (Kubernetes, etc.)
