Security Best Practices

Recommended security configurations and practices

• Use specific image tags for production (avoid latest)
• Configure resource limits: memory and CPU constraints
• Enable read-only root filesystem when possible
• Run containers with non-root user (--user 1000:1000)
• Use --security-opt=no-new-privileges flag
• Regularly update container images for security patches
• Implement proper network segmentation
• Monitor container metrics for anomalies
