kubectl-cluster

kubectl-cluster is a tool to display/switch between Kubernetes clusters (and configure them for kubectl) easily.

Examples

list clusters from your KUBECOMFIG

Usages

# list clusters
kubectl cluster

# swith context with cluster name
kubectl cluster <cluster>

Installation

with go install

go install github.com/sp-yduck/kubectl-cluster@latest

How it works

The relationship between cluster and context is "one to many". kubectl-cluster uses the newest context which using specified cluster.

for example, if your kubeconfig looks like following and you chose cluster==docker-desktop , kubectl-cluster will switch your current-context to kubernetes-admin@docker-desktop as this is the newest context in this kubeconfig.

clusters:
- cluster:
  name: docker-desktop
- cluster:
  name: kubernetes
- cluster:
  name: rancher-desktop
contexts:
- context:                      # here is first context using cluster:docker-desktop
    cluster: docker-desktop
  name: docker-desktop
- context:
    cluster: kubernetes
  name: kubernetes-admin@kubernetes
- context:
    cluster: rancher-desktop
  name: rancher-desktop
- context:                      # here is newest context using cluster:docker-desktop
    cluster: docker-desktop
    user: admin
  name: kubernetes-admin@docker-desktop
current-context: docker-desktop
