Quick Start

Get your first virtual cluster running in under 5 minutes

1

Install the vCluster CLI

Install the vCluster CLI on your local machine using your preferred package manager.
brew install loft-sh/tap/vcluster
Verify the installation:
vcluster --version
2

Create your virtual cluster

Create your first virtual cluster with a single command. Make sure you have a Kubernetes cluster and kubectl configured.
vcluster create my-vcluster --namespace team-x
This command creates a namespace team-x, deploys a virtual cluster named my-vcluster, and automatically connects your kubectl context to it.
3

Use kubectl as normal

You’re now connected to your virtual cluster! Use kubectl just like you would with any Kubernetes cluster.
# Create a namespace inside the virtual cluster
kubectl create namespace demo

# Deploy a workload
kubectl create deployment nginx --image=nginx -n demo

# View resources
kubectl get pods -n demo

NAME                     READY   STATUS    RESTARTS   AGE
nginx-7854ff8877-k2qvw   1/1     Running   0          10s
4

Manage your virtual clusters

List all your virtual clusters and manage them with the CLI.
# List all virtual clusters
vcluster list

# Disconnect from the virtual cluster
vcluster disconnect

# Reconnect anytime
vcluster connect my-vcluster --namespace team-x

# Delete when done
vcluster delete my-vcluster --namespace team-x
