VXLAN Overlay Networks

Virtual networks using VXLAN encapsulation to enable container communication across hosts.

Valet Key Pattern for Secure Resource Access

Design pattern for providing clients with restricted direct access to a specific resource or service.

Validating Webhooks

Admission controller webhooks in Kubernetes that validate resource requests without modifying them.

Validation Webhooks

Kubernetes admission control mechanism for validating API requests against custom logic before persistence.

Velero for Backup and Restore

Open-source tool for backing up and restoring Kubernetes cluster resources and persistent volumes.

Version Skew Policy

Guidelines defining supported version differences between Kubernetes components to ensure compatibility.

Vertical Pod Autoscaler

Kubernetes component that automatically adjusts the CPU and memory reservations for pods to optimize resource utilization.
