Kubernetes Cluster

Go to Terms and Definitions

A Kubernetes Cluster is a coordinated computing platform comprising Kubernetes control-plane components and one or more worker nodes that schedule, execute, connect, and manage containerized workloads.

A Kubernetes Cluster may include:

• Kubernetes control-plane components
• Worker nodes
• Cluster networking
• Service discovery
• Storage integration
• Identity and access configuration
• Admission controls
• Security controls
• Monitoring integration
• Logging integration

The control plane manages the desired and observed state of Kubernetes resources.

Worker nodes execute the containers and supporting runtime components associated with deployed Containerized Workloads.

A Kubernetes Cluster differs from a container runtime:

• A container runtime creates and operates containers
• A Kubernetes Cluster coordinates containers, workloads, resources, scheduling, networking, and related platform behavior across one or more nodes

A Kubernetes Cluster may operate:

• Within a single Infrastructure Environment
• Across multiple availability zones
• On physical machines
• On Virtual Machines
• Through a provider-managed service
• In a Connected, Disconnected, or Air-Gapped Environment

A Kubernetes Cluster does not by itself establish that the cluster is:

• Securely configured
• Highly available
• Compliant
• Connected to an external network
• Suitable for production use
• Authorized to execute a particular Workload

Separate requirements govern those determinations.

The term does not prescribe a Kubernetes distribution, version, installation method, node topology, container runtime, network implementation, storage implementation, or provider.
