Containerization & Orchestration Glossary

From Docker to Kubernetes to Terraform, your passport to the containerized world of modern deployment.

Vertical Pod Autoscaler

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

Vertical Pod Autoscaler Metrics

Resource utilization data used by VPA to make decisions on adjusting pod resource allocations.

Vertical Pod Autoscaler with Custom Metrics

Extended VPA functionality allowing scaling decisions based on application-specific metrics.

VerticalPodAutoscaler

Kubernetes resource defining the behavior for automatically adjusting pod resource requests and limits.

Virtual Clusters

Isolated environments within a physical Kubernetes cluster, providing multi-tenancy and resource isolation.

Virtual IP (VIP)

Single IP address representing a service, used for load balancing in container networking.

Virtual Kubelet

Kubernetes kubelet implementation that masquerades as a node and schedules pods on non-Kubernetes platforms.

Volume Access Modes (ReadWriteOnce, ReadOnlyMany, ReadWriteMany)

Kubernetes volume properties (ReadWriteOnce, ReadOnlyMany, ReadWriteMany) defining how a volume can be mounted.

Volume Cloning

Process of creating a new volume populated with the contents of an existing volume in Kubernetes.

Volume Expansion

Feature allowing the size of a persistent volume to be increased without recreating the volume.

Volume Health Monitoring

Kubernetes feature for detecting and reporting issues with persistent volumes to ensure data integrity.

Volume Modes (Block, Filesystem)

Kubernetes volume properties (Block, Filesystem) defining how the storage is presented to the container.

Volume Mounting

Process of making a storage volume accessible within a container's filesystem, enabling data persistence.

Volume Mounts

Specifications in Kubernetes pod definitions declaring how volumes should be mounted into containers.

Volume Plugins

Kubernetes components enabling integration with various storage systems for persistent storage.

Volume Snapshots

Point-in-time copies of volumes in Kubernetes, used for backup, restoration, or cloning of persistent data.

Vulnerability Scanning Integration

Incorporation of security scanning tools into the container build and deployment pipeline.

Weave GitOps

Set of tools for implementing GitOps workflows in Kubernetes environments, automating deployment and management.

Weave Net

Software-defined networking solution for containerized applications, providing a virtual network across hosts.

Weave Net for Multi-host Docker Networking

Use of Weave Net to create a virtual network connecting Docker containers across multiple hosts.

WebAssembly (Wasm) in Containers

Use of WebAssembly runtimes in containers for portable, secure, and high-performance applications.

WebAssembly in Service Mesh

Integration of WebAssembly modules in service mesh proxies for customizable traffic management.

Webhook Admission Controllers

External services invoked during the Kubernetes admission process to validate or mutate API requests.

Webhook Authorization

Kubernetes authorization mode delegating access decisions to an external REST service, enabling custom auth logic.

Webhook Token Authentication

Kubernetes authentication method verifying bearer tokens against an external webhook service.
