## Prepare K8s

How to run Kubernetes with Ignite support:

`$ docker-compose -f vkignite.yaml up`

Wait until `kubeconfig.yaml` is written into the current dir.

`$ export KUBECONFIG=$PWD/kubeconfig.yaml`

Run get nodes and you'll see:

```

$ kubectl get nodes

NAME     STATUS   ROLES   AGE     VERSION

ignite   Ready    agent   5h12m   v1.14.3-ignite-f5516fe-dev

```

## Define a Virtual Machine

Apply the Custom Resource Definition to Kubernetes to allow VM creation via `kubectl`.

```

$ kubectl apply -f crd/vm_crd.yaml

```

Then open an editor to define a VM with the above CRD.

```

apiVersion: chanwit.github.com/v1alpha1

kind: VirtualMachine

metadata:

  name: my-vm

spec:

  kernel: weaveworks/ignite-kernel:4.19.47

  image: weaveworks/ignite-ubuntu:latest

  cpus: 1

  memory: 512M

  diskSize: 1GB

```

save it as `examples/my-vm.yaml`.

The `VirtualMachine` CRD is the simplified counter-part of Ignite's `v1alpha1` config.

## Provision the VM

We then could be able to create a VM by:

```

$ kubectl apply -f examples/my-vm.yaml

```

To see that the VM is already provisioned:

```

$ kubectl get vm,pod

NAME                                      CPUS   MEMORY   SIZE   STATE

virtualmachine.chanwit.github.com/my-vm   1      512M     1GB    Running

NAME        READY   STATUS    RESTARTS   AGE

pod/my-vm   1/1     Running   0          12m

```

Then you now will be able to use `sudo ignite ssh default__my-vm` to get into the VM.

The VM name is in the `{namespace}__{name}` pattern.

To delete the VM,

```

$ kubectl delete vm my-vm

```
