Smoke test the cluster

If all has gone well, a cluster will now be running on your local system comprising of 3 nodes and a workstation.

We can check status by now switching directory to the vagrant dev folder and running a vagrant status command :

cd vagrant/dev/ubuntu/
vagrant status
Current machine states:

vm1                       running (virtualbox)
vm2                       running (virtualbox)
vm3                       running (virtualbox)
workstation               running (virtualbox)

This environment represents multiple VMs. The VMs are all listed
above with their current state. For more information about a specific
VM, run `vagrant status NAME`.

To work on our cluster we must first connect to the workstation and then use kubectl commands to interact with k3s :

vagrant ssh workstation

From the workstation, use kubectl to access our cluster

kubectl get nodes
NAME   STATUS   ROLES                       AGE     VERSION
vm1    Ready    control-plane,etcd,master   4h11m   v1.33.3+k3s1
vm2    Ready    control-plane,etcd,master   4h11m   v1.33.3+k3s1
vm3    Ready    control-plane,etcd,master   4h10m   v1.33.3+k3s1

If you have got this far, congratulation you have a locally hosted k3s cluster running in 3 virtual machines and a workstation that can be used to manage it using kubectl and ansible.
