Overview
kind is a tool for running local Kubernetes clusters using Docker container as cluster nodes. kind was primarily designed for testing Kubernetes itself, but may be used for local development or CI.
Cluster
A Kubernetes cluster can be created with kind create cluster. The "nodes" are implemented as Docker containers. Upon creation of a default cluster, it will report two nodes, "kind-control-plane" and "kind-worker". The corresponding Docker containers are:
CONTAINER ID IMAGE [...] NAMES 3108457ff1b6 [...]/kind:v1.27.3-3966ac76 kind-worker c90cb24cc040 [...]kind:v1.27.3-3966ac76 kind-control-plane 2702defb0752 [...]/registry:2 kind-registry
What is a kind cluster? Where does it live?
"Node" Image
The “node” image is a Docker image for running nested containers, systemd, and Kubernetes components.
