Concepts

Overview

Get a high-level outline of Kubernetes and the components it is built from.

Cluster Architecture

The architectural concepts behind Kubernetes.

Containers

Technology for packaging an application along with its runtime dependencies.

Workloads

Understand Pods, the smallest deployable compute object in Kubernetes, and the higher-level abstractions that help you to run them.

Services, Load Balancing, and Networking

Concepts and resources behind networking in Kubernetes.

Storage

Ways to provide both long-term and temporary storage to Pods in your cluster.

Configuration

Resources that Kubernetes provides for configuring Pods.

Security

Concepts for keeping your cloud-native workload secure.

Policies

Policies you can configure that apply to groups of resources.

Scheduling and Eviction

In Kubernetes, scheduling refers to making sure that Pods are matched to Nodes so that the kubelet can run them. Eviction is the process of proactively failing one or more Pods on resource-starved Nodes.

Cluster Administration

Lower-level detail relevant to creating or administering a Kubernetes cluster.

Extending Kubernetes

Different ways to change the behavior of your Kubernetes cluster.
