From YouTube: KubeVirt Operator Demo

Description

https://kubevirt.io/

A

Hello, everybody today I want to give you a short demonstration of the new cube root operator. The operator has a limited feature set at the moment, especially it does not support updates. Yet it will just install cube root from the same image repository and with the same image tag as you use for the operator itself. Let's start I have a single node kubernetes cluster running here there is no ports yet in our cube root namespace.

A

So the first thing I need to do is install the cube root operator. Let's have a look at its manifest.

A

So the manifest contains the namespace if it doesn't exist, yet the custom resource definition for the queue for application and then some Auto indication authorization configuration and finally, the deployment of the cube root operator itself also nothing special here. Let's install.

A

So the container is creating last: let's wait until it's ready.

A

A

And it's ready, so let's just do a quick check. Yes, we have a new custom resource definition for the Cupid application available, so for installing Keifer. Now we need to deploy a Cupid custom resource. Let's save a look at it.

A

So at the moment this is very simple, not much to config yet because, as I mentioned earlier, it will just install the same version as we use for the operator.

A

So, let's deploy and wait until it's ready in this window. We can monitor the progress, so it deployed the API and the controller and Verte and they are all running now. Our wait command is still waiting for the ready condition.

A

First, one is ready.

A

And the last one will be ready soon, I hope.

A

Here we go also the wait command finished. Let's have a look at the custom resource for secured application.

A

So here, especially in the status you see that we have two conditions on it, so one it's a created condition that will be set when all resources are created and then we have the ready condition, which means that all Cupit components are ready. Also, you see the version of the operator and also the version of cube. Would it serve so now cubed is running I skip showing starting our VM, so to make it a bit quicker.

A

The last thing I want to show is how you can uninstall cube root for that you just need to delete the custom resource, and since we use a finalizer on it,.

A

It will be, it will be ready as soon as everything is marked for religion.
