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.
