vcluster

Playing with vcluster

Requirements

• minikube
• kubectl
• vcluster cli (brew install vcluster)

Start a K8s cluster

minikube start

Install and run vclusters

Install two vclusters (cluster-1 and cluster-2) with helm:

helm upgrade --install cluster-1 vcluster \
  --values vcluster.yaml \
  --repo https://charts.loft.sh \
  --create-namespace \
  --namespace cluster-1 \
  --kube-context minikube

helm upgrade --install cluster-2 vcluster \
  --values vcluster.yaml \
  --repo https://charts.loft.sh \
  --create-namespace \
  --namespace cluster-2 \
  --kube-context minikube

List and interact with both clusters

List vclusters:

vcluster list

Connect to clusters (leave each terminal open):

vcluster connect cluster-1 --kube-config-context-name cluster-1 --context minikube
vcluster connect cluster-2 --kube-config-context-name cluster-2 --context minikube

And finally, list pods in both clusters, for example:

kubectl get pods --context cluster-1

kubectl get pods --context cluster-2

Cleanup

Delete vclusters:

vcluster delete --delete-namespace cluster-1 --context minikube
vcluster delete --delete-namespace cluster-2 --context minikube

Delete K8s cluster:

minikube delete -p minikube
