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

Recommended security context for Kubernetes deployments

securityContext:
  runAsNonRoot: true
  runAsUser: 1000
  runAsGroup: 1000
  readOnlyRootFilesystem: true
  allowPrivilegeEscalation: false
  capabilities:
    drop: ['ALL']
