# MongoDB Health Check Fix

## Problem
The MongoDB container was failing health checks with the original configuration:

```yaml
healthcheck:
  test: ['CMD', 'mongosh', '--eval', 'db.adminCommand.ping()']
  start_period: 10s  # Too short!
```

## Root Causes
1. **start_period too short**: 10s isn't enough for MongoDB to initialize, especially on first start
2. **Command format**: The healthcheck needs proper output handling

## Solution
Updated healthcheck in docker-compose.dev.yml:

```yaml
healthcheck:
  test: |
    mongosh --eval "db.adminCommand('ping').ok" --quiet
  interval: 10s
  timeout: 5s
  retries: 5
  start_period: 40s  # Increased from 10s to 40s
```

## Changes Made
- ✅ Increased `start_period` from 10s to 40s (gives MongoDB time to initialize)
- ✅ Simplified the healthcheck command to use shell format
- ✅ Added `--quiet` flag to suppress verbose output

## How to Apply
On your server:

```bash
# Pull the latest changes
git pull origin main

# Stop and remove existing containers
docker compose -f docker-compose.dev.yml down -v

# Start fresh
docker compose -f docker-compose.dev.yml up -d

# Watch the logs
docker compose -f docker-compose.dev.yml logs -f mongodb
```

## Verify Health Check
```bash
# Check container health
docker ps --format "table {{.Names}}	{{.Status}}"

# Check health status specifically
docker inspect normogen-mongodb-dev --format='{{.State.Health.Status}}'
```

Expected output: `healthy`
