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

Kubernetes Security Context
