Contexte kubectl vs cluster

Question

Dans le monde de la configuration kubectl et kubernetes, quelle est la différence entre le contexte et un cluster? Par exemple, je vois ces commandes:

Available Commands:
  current-context Displays the current-context
  delete-cluster  Delete the specified cluster from the kubeconfig
  delete-context  Delete the specified context from the kubeconfig
  get-clusters    Display clusters defined in the kubeconfig
  get-contexts    Describe one or many contexts
  rename-context  Renames a context from the kubeconfig file.
  set             Sets an individual value in a kubeconfig file
  set-cluster     Sets a cluster entry in kubeconfig
  set-context     Sets a context entry in kubeconfig

et dans .kube/config je vois:

- context:
    cluster: arn:aws:eks:us-west-2:91XXXXXXX71:cluster/ignitecluster
    namespace: ignite
    user: arn:aws:eks:us-west-2:91XXXXXXX71:cluster/ignitecluster
  name: arn:aws:eks:us-west-2: 91XXXXXXX71:cluster/ignitecluster

De https://cloud.google.com/kubernetes-engine/docs/how-to/cluster-access-for-kubectl#kubeconfig :

A context is a group of access parameters.
Each context contains a Kubernetes cluster, a user, and a namespace.
The current context is the cluster that is currently the default for kubectl:
all kubectl commands run against that cluster

Ainsi, contextX = {clusterX, userX, namespaceX}
