This is the solution video for DKA of greed Labbe.
So let's wait for the first question to load up.
And the first question, this lab test your skills on a breeding ground in this cluster, we have a
production cluster with applications running on it.
Let us explore the set up first.
What is the current of the cluster?
All right.
So let's go to the Domna and type in cube.
You'll get notes.
And here, at least, the cumulate version of Boudinot master, another one, and you can see that the
vision is one dot one seven zero.
And to see the cluster version, we can also run Cube CTCA version.
And makers of Dashty Short Flag.
And here you can see that the silver version is one out, one seven.
How many nodes are part of this cluster?
We already saw that there is a massive node and not zero one, which is the focus.
So the answer is to.
How many nodes can host Workload's in the cluster?
To find this latest round Kubek deal, get Pott's.
And we'll use the natural option.
And here we can see that we have two pots and they are running on Masser and not the other one, so
the exact option is to.
How many applications are hosted on the cluster, so let's check the deployments for that.
And there is one deployment by the name of Fred.
What roads are the potholes around?
So we already saw that it's running on Muser as well as Nunziata one, so let's select that.
You are tasked to upgrade the cluster users, accessing the application must not be impacted and you
cannot provision new VMS.
What strategy would you use to upgrade the cluster?
So if you have gone to the lecture, we have already seen that in such circumstances, we have to upgrade
the node one by one and move close to the other, nor of the cluster so that the application is not
affected.
So that secret option.
What is the latest cable version available for upgrade, so let's use Kube EDM tool and find out the
latest available version.
So clear the screen.
And let's right cube Kubica.
Sorry, that should be.
Cube, Adam.
Plan.
And here you can see that the latest version that is available as vision one dot one seven, dot 11.
We'll be upgrading the muscle, not first green, the muscle note of workload's and market on schedule
will.
Fathers will make use of the U.S. children, come on.
So they can see it is already affecting parts from M. So it should not be hosting any more pods once
this command is complete and it should also market on schedule, Will.
So new parts will not be scheduled on the master.
So let's wait for this command to complete.
And then miraculously still get notes, you'll see that scheduling is disabled for master.
Upgrade the muscle components to the exact vision one, not one aid, upgrade the cube Alium tool first,
then the muscle components and finally the Kubelik.
All right, so let's first upgrade the cube idiom to we already saw that it's on Vision one one seven,
but let's validate that anyway.
So you can see that it is on within one two one seven, so first thing would be to upgrade it.
So for those will use out and stall and sort of upgrade.
Out and stole KUB, LDM and the exact execution so you give is equal to one dot, one eight zero zero
zero.
So they should install the latest Ubaidi motion or the exact the motion one dot, one aide or the current
version, which is one out, one seven.
So it's when you're ready.
And let's wait for the installation to complete.
All right, so let's check the region again.
And now it's running version one not wanted.
So the next step is to upgrade the cluster, so we'll use Kube EDM upgrade appli version one dot one
eight zero.
That's the exact version that we want to agree to.
Currently it's on one dot, one seven.
So when you execute this command, it will run a bunch of pre-flight checks and if there are any errors,
it will not let you proceed.
So in this case, everything looks to be in order.
So hit.
Yes.
Or y when you're ready to proceed.
And right now, let's wait for the upgrade to complete for the cluster.
As you can see, it is currently upgrading the control plane components.
So this can take a couple of minutes.
All right, so the cluster is now agreed to one that wanted.
To validate this, we can again on Kubek Delusion.
And here you can see that isover vision is one part, one eight cubicle client vision as one one seven.
So if we can agree that if needed.
But let's move on to the next step.
If you're on Cube CTA, get notes, you'll see that division is still one dot, one seven.
That's because the cube led vision has not been updated yet.
So let's use the same command as before.
And instead of medium, let's type in cumulate.
So wait for the Kuebler process to come up, that can take a couple of minutes as well.
So if you see this mess, they just give it a minute or two.
And now you can see that the evolution of M.S. one dot, one eight, which is what we desire.
So let's move on to the next question.
All right, next, we have to mark the must note as scheduled, well, again, and to do this, we will
use the cubicle uncowed on command.
And now from the U.S., they'll get NATO to concede that it is in already relisted.
Next, as the volcano drained, the volcano of will close and market on schedule.
So let's use the same commanders before it just keeps cold rain
and in this case will select another one.
Secured still get those shoes that no one is the one right now, which is disabled for scheduling.
So now let's agree, cannot do the exact version 1.0 on it, so let's get into another one.
So I'm going to switch from the masseur to another one.
It has password less SSX enabled so you don't have to enter a password.
So, as before, let's update the committee to before, so I run the exact same command as before.
Being is equal to here.
So we'll essentially follow the same process as before what we carried out in the Senate.
We will upgrade the EDM tools first and then upgrade the node configuration using cube medium.
And then finally, we'll upgrade the cube, let.
So next, let's upgrade the node configuration.
So the correct come on is cube a.T.M, great node.
And this is a very small process, adopted the Kuebler configuration, as you can see, it, is using
the wooden one, not one end of the conflict map.
And that said, let's now agree, the cube cube let.
So exactly the same commanders before I accept that we will select cumulate to be upgraded right now.
And that said, let's now head back to the muscle, not using control to log out and now I'm back in
the muscle not.
And if Iran keeps it, you'll get Newsweek division as one that won it for both Muser another one.
And finally, let us remove the restriction and Mike Deaver can always schedule a well again, so let's
try and keep clear, unquote, on that one and verify it once.
And here we have now both nodes of the cluster which are in already state and which are running within
one dot, one eight.
So that was the last question.
Thank you for joining me in this situation video.
I'll see in the next one.
