|
|
- ⚠️ Consider running as non-root user
|
|
|
|
## 📊 Resource Requirements
|

No resource limits configured
|
|
|
|
### Recommended Resources
|
|
- **Minimum RAM**: 512MB
|
|
- **Recommended RAM**: 1GB+
|
|
- **CPU**: 1 core minimum
|
|
- **Storage**: Varies by usage
|
|
|
|
### Resource Monitoring
|
|

|
|
|
|
## 🔍 Health Monitoring
|
|
|
|
⚠️ No health check configured
|
|
Consider adding a health check:
|
|
```yaml
|
|
healthcheck:
|
|
test: ["CMD", "curl", "-f", "http://localhost:PORT/health"]
|
|
interval: 30s
|
|
timeout: 10s
|
|
retries: 3
|
|
```
|
|
|
|
### Manual Health Checks
|
|
```bash
|
|
# Check container health
|
|
docker inspect --format='{{.State.Health.Status}}' CONTAINER_NAME
|
|
|
|
# View health check logs
|
|
docker inspect --format='{{range .State.Health.Log}}{{.Output}}{{end}}' CONTAINER_NAME
|
|
```
|
|
|
|
## 🚨 Troubleshooting
|
|
|
|
### Common Issues
|
|
**Service won't start**
|
|
- Check Docker logs: `docker-compose logs service-name`
|
|
- Verify port availability: `netstat -tulpn | grep PORT`
|
|
- Check file permissions on mounted volumes
|
|
|
|
**Can't access web interface**
|
|
- Verify service is running: `docker-compose ps`
|
|
- Check firewall settings
|
|
- Confirm correct port mapping
|
|
|
|
**Performance issues**
|
|
- Monitor resource usage: `docker stats`
|
|
- Check available disk space: `df -h`
|
|
- Review service logs for errors
|
|
|
|
### Useful Commands
|
|
```bash
|
|
# Check service status
|
|
docker-compose ps
