Platform glossary

This page contains definitions for common terms used throughout the platform documentation.

Access Key

A secure credential in the platform that allows programmatic access to platform resources and API endpoints.

Related terms: The Platform, User

Admission Control

A Kubernetes feature that intercepts requests to the API server prior to persistence of the object, allowing for validation, mutation, or rejection of requests based on configured policies.

Related terms: API Server, Control Plane

API Server

The core component of Kubernetes that exposes the Kubernetes API. It is the front-end for the Kubernetes control plane and handles all REST operations, validating and configuring data for API objects.

Related terms: Control Plane, rate-limiting

Control Plane

The container orchestration layer that exposes the API and interfaces to define, deploy, and manage the lifecycle of containers. In vCluster, each virtual cluster has its own control plane components.

Related terms: API Server, vCluster

K0s

A lightweight, certified Kubernetes distribution that can be used in virtual clusters as an alternative to K3s or standard Kubernetes.

Related terms: K3s, K8s

K3s

A lightweight, certified Kubernetes distribution often used as the default distribution for virtual clusters due to its minimal resource requirements and fast startup time.

Related terms: K8s, K0s

K8s

The standard Kubernetes distribution that can be used in virtual clusters, offering full compatibility with upstream Kubernetes features.

Related terms: K3s, K0s

Namespace

A Kubernetes namespace that can be managed by the platform, providing isolation for resources within a cluster.

Related terms: Project

Project

A logical grouping of resources in the platform that provides team isolation and resource quotas. Projects help organize virtual clusters and namespace resources.

Related terms: The Platform, Team

Sleep Mode

A platform feature that allows virtual clusters or namespaces to be paused when inactive, conserving resources and reducing costs.

Related terms: The Platform

Team

A group of users in the platform with shared access to specific projects and resources.

Related terms: Project, User

Template

A reusable configuration pattern in the platform that defines the settings and resources for creating new virtual clusters or namespaces.

Related terms: The Platform, Virtual Cluster Template

The Platform

The vCluster Platform that provides management, access control, and operational features for virtual clusters across multiple physical host clusters.

Related terms: Project

User

An individual account in the platform with specific access permissions to projects and resources.

Related terms: Team

Virtual Cluster Template

A predefined configuration in the platform for creating virtual clusters with consistent settings, policies, and resources.
